The Columbine High School massacre was a school shooting that occurred on April 20, 1999, at Columbine High School in Columbine, an unincorporated area of Jefferson County, Colorado, U.S. In addition to the shootings, the complex and highly planned attack involved a fire bomb to divert firefighters, propane tanks converted to bombs placed in the cafeteria, 99 explosive devices, and car bombs. The perpetrators, senior students Eric Harris and Dylan Klebold, murdered 12 students and one teacher. They injured 21 additional people, and three more were injured while attempting to escape the school. The pair subsequently committed suicide.
Although their precise motives remain unclear, the personal journals of the perpetrators document that they wished their actions to rival the Oklahoma City bombing and other deadly incidents in the United States in the 1990s. The attack has been referred to by USA Today as a "suicidal attack [that was] planned as a grand—if badly implemented—terrorist bombing." The massacre has been reported as "the deadliest high school shooting in U.S. history."
The massacre sparked debate over gun control laws, high school cliques, subcultures, and bullying. It resulted in an increased emphasis on school security with zero tolerance policies, and a moral panic over goth culture, gun culture, social outcasts, the use of pharmaceutical anti-depressants by teenagers, teenage Internet use, and violence in video games.

In 1996, Eric Harris created a private website on America Online. Harris initially created the site to host gaming levels he and his friend, Dylan Klebold, created for use in the video game Doom, primarily for friends. On this site, Harris began a blog, which included jokes and short journal entries with thoughts on parents, school, and friends. By the end of the year, the site contained instructions on how to cause mischief, as well as instructions on how to make explosives, and blogs in which he described the trouble he and Klebold were causing. Beginning in early 1997, the blog postings began to show the first signs of Harris's ever-growing anger against society.
Harris's site attracted few visitors, and caused no concern until March 1998. Klebold gave the web address to Brooks Brown, a former friend of Harris. Brown's mother had filed numerous complaints with the Jefferson County Sheriff's office concerning Harris, as she thought he was dangerous. The website contained numerous death threats directed against Brown: Klebold knew that if Brooks accessed the address, he would discover the content and inform his parents, and likely the authorities would be notified. After Brown's parents viewed the site, they contacted the Jefferson County Sheriff's Office. The investigator Michael Guerra was told about the website. When he accessed it, Guerra discovered numerous violent threats directed against the students and teachers of Columbine High School. Other material included blurbs that Harris had written about his general hatred of society, and his desire to kill those who annoyed him.
Harris had noted on his site that he had made pipe bombs, in addition to a hit list of individuals (he did not post any plan on how he intended to attack targets). As Harris had posted on his website that he possessed explosives, Guerra wrote a draft affidavit, requesting a search warrant of the Harris household. The affidavit also mentioned a suspicion of Harris being involved in an unsolved pipe bomb case in February 1998. The affidavit was never filed. It was concealed by the Jefferson County Sheriff's Office and not revealed until September 2001, resulting from an investigation by the TV show 60 Minutes.
After the revelation about the affidavit, a series of grand jury investigations were begun into the cover-up activities of Jefferson County officials. The investigation revealed that high-ranking county officials had met a few days after the massacre to discuss the release of the affidavit to the public. It was decided that because the affidavit's contents lacked the necessary probable cause to have supported the issuance of a search warrant for the Harris household by a judge, it would be best not to disclose the affidavit's existence at an upcoming press conference, although the actual conversations and points of discussion were never revealed to anyone other than the grand jury members. Following the press conference, the original Guerra documents disappeared. In September 1999, a Jefferson County investigator failed to find the documents during a secret search of the county's computer system. A second attempt in late 2000 found copies of the document within the Jefferson County archives. The documents were reconstructed and released to the public in September 2001, but the original documents are still missing. The final grand jury investigation was released in September 2004.
On January 30, 1998, Harris and Klebold stole tools and other equipment from a van parked near the city of Littleton. Both youths were arrested and subsequently attended a joint court hearing, where they pleaded guilty to the felony theft. The judge sentenced the duo to attend a juvenile diversion program. There, both boys attended mandated classes and talked with diversion officers. One of their classes taught anger management. Harris also began attending therapy classes with a psychologist. Klebold had a history of drinking and had failed a dilute urine test, but neither he nor Harris attended any substance abuse classes.
Harris and Klebold were eventually released from diversion several weeks early because of positive actions in the program; they were both on probation. Shortly after Harris' and Klebold's court hearing, Harris's online blog disappeared. His website was reverted to its original purpose of posting user-created levels of Doom. Harris began to write in a journal, in which he recorded his thoughts and plans. In April 1998, as part of his diversion program, Harris wrote a letter of apology to the owner of the van. However, around the same time, he furiously derided him in his journal, stating that he believed himself to have the right to steal something if he wanted to. Harris continued his scheduled meetings with his psychologist until a few months before he and Klebold committed the Columbine High School massacre.
Harris dedicated a section of his website to posting content regarding his and Klebold's progress in their collection of guns and building of bombs (they subsequently used both in attacking students at their school). After the website was made public, AOL permanently deleted it from its servers.
In one scheduled meeting with his appointed psychiatrist, Harris had complained of depression, anger, and suicidal thoughts. As a result, he was prescribed the anti-depressant Zoloft. He complained of feeling restless and having trouble concentrating; in April, his doctor switched him to Luvox, a similar anti-depressant drug.
Their journals documented their plan for a major bombing to rival that of the Oklahoma City bombing. Their entries contained blurbs about ways to escape to Mexico, hijacking an aircraft at Denver International Airport and crashing it into a building in New York City (foreshadowing the September 11 attacks by two years), and details about the planned attack. The pair hoped that, after detonating their home-made explosives in the cafeteria at the busiest time of day, killing hundreds of students, they would shoot survivors fleeing from the school. Then, as police vehicles, ambulances, fire trucks, and reporters came to the school, bombs set in the boys' cars would detonate, killing these emergency and other personnel. That did not happen, since these explosives did not detonate.
The pair kept videos that documented the explosives, ammunition, and weapons they had obtained illegally. They revealed the ways they hid their arsenals in their homes, as well as how they deceived their parents about their activities. The pair shot videos of doing target practice in nearby foothills, as well as areas of the high school they planned to attack. On April 20, approximately thirty minutes before the attack, they made a final video saying goodbye and apologizing to their friends and families.
In the months prior to the attacks, Harris and Klebold acquired two 9 mm firearms and two 12-gauge shotguns. Their friend, Robyn Anderson, had inadvertently bought a rifle and the two shotguns used in the massacre at the Tanner Gun Show in December 1998. Through Philip Duran, another friend, Harris and Klebold later bought a handgun from Mark Manes for $500.
Using instructions obtained via the Internet, Harris and Klebold constructed a total of 99 improvised explosive devices of various designs and sizes. They sawed the barrels and butts off their shotguns to make them easier to conceal.
On the day of the massacre, Harris was equipped with a 12-gauge Savage-Springfield 67H pump-action shotgun (which he discharged a total of 25 times) and a Hi-Point 995 Carbine 9 mm carbine with thirteen 10-round magazines (which he fired a total of 96 times).
Klebold was equipped with a 9×19mm Intratec TEC-9 semi-automatic handgun with one 52-, one 32-, and one 28-round magazine and a 12-gauge Stevens 311D double-barreled sawed-off shotgun. Klebold primarily fired the TEC-9 handgun for a total of 55 times, while he discharged a total of 12 rounds from his double-barreled shotgun.
On the morning of Tuesday, April 20, 1999, Harris and Klebold placed a small fire bomb in a field about three miles south of Columbine High School, and two miles south of the fire station. Set to explode at 11:14 a.m., the bomb was intended as a diversion to draw firefighters and emergency personnel away from the school (it partially detonated and caused a small fire, which was quickly extinguished by the fire department).
At 11:10 a.m., Harris and Klebold arrived separately at Columbine High School. Harris parked his vehicle in the junior student parking lot, by the south entrance, and Klebold parked in the adjoining senior student parking lot, by the west entrance. The school cafeteria, their primary bomb target, with its long outside window-wall and ground-level doors, was between their parking spots.
After parking their cars, each containing concealed car bombs timed to detonate at 12:00,  the duo met near Harris' car and armed a further two 20 pounds (9.1 kg) propane bombs before entering the cafeteria a few minutes prior to the beginning of the "A" lunch shift. The youths placed the duffel bags containing the bombs, set to explode at approximately 11:17a.m., inside the cafeteria before returning to their separate vehicles to await the explosion and shoot survivors fleeing the building. Had these bombs exploded with full power, they would have killed or severely wounded all 488 students in the cafeteria and possibly collapsed the ceiling, dropping part of the library into the cafeteria.
A Jefferson County Sheriff's Deputy, Neil Gardner, was assigned to the high school as a full-time uniformed and armed school resource officer. Gardner usually ate lunch with students in the cafeteria, but on April 20 he was eating lunch in his patrol car at the northwest corner of the campus, watching students in the Smokers' Pit in Clement Park. The security staff at Columbine did not observe the bombs being placed in the cafeteria, since a custodian was replacing the school security video tape as it happened. The bags holding the bombs were first visible on the fresh security tape, but they were not identified as suspicious items. No witness recalled seeing the duffel bags being added to the 400 or so backpacks already in the cafeteria.
As the two youths returned to their vehicles, Harris encountered Brooks Brown, a friend and classmate with whom he had recently patched up a longstanding series of disagreements. Brown, who was in the parking lot smoking a cigarette, was surprised to see Harris, whom he had earlier noted had been absent from an important class test. Harris seemed unconcerned when reminded of this fact by Brown, commenting, "It doesn't matter anymore." Harris then elaborated: "Brooks, I like you now. Get out of here. Go home." Brown, feeling uneasy, walked away. Several minutes later, students departing Columbine for their lunch break observed Brown heading down South Pierce Street away from the school. Meanwhile, Harris and Klebold armed themselves by their vehicles and waited for the bombs to explode.
When the cafeteria bombs failed to explode, Harris and Klebold convened and walked toward the school. Both armed, they climbed to the top of the outdoor west entrance steps, placing them on a level with the athletic fields west of the building and the library inside the west entrance, directly above the cafeteria. From this vantage point, the cafeteria's west entrance was located at the bottom of the staircase, next to the senior parking lot.
At 11:19 a.m., 17-year-old Rachel Scott was having lunch with friend Richard Castaldo while sitting on the grass next to the west entrance of the school. Castaldo said he saw one of the boys throw a pipe bomb, which only partially detonated. Thinking the bomb was no more than a crude senior prank, Castaldo did not take it seriously. At that moment, a witness heard Eric Harris yell, "Go! Go!" The two gunmen pulled their guns from beneath their trench coats and began shooting at Castaldo and Scott. Scott was hit four times and killed instantly. Castaldo was shot eight times in the chest, arm, and abdomen and paralyzed below the chest, falling into unconsciousness. It is unknown who fired first; however, Harris was the one who shot and killed Scott, and Castaldo reported that Scott was hit before he was.
After the first two shootings, Harris removed his trench coat and aimed his 9 mm carbine down the west staircase toward three youths: 15-year-olds Daniel Rohrbough and Sean Graves and 16-year-old Lance Kirklin. The three friends had been ascending the staircase directly below the shooters. Kirklin later reported seeing Klebold and Harris standing at the top of the staircase before the pair opened fire. All three youths were shot and wounded. Inside the school, some of the students had believed that they were bearing witness to a senior prank by the two seniors. But in the cafeteria, Dave Sanders, a computer and business teacher as well as a varsity coach, quickly realized it was not a prank but a deliberate attack on the school.
Harris and Klebold turned and began shooting west in the direction of five students sitting on the grassy hillside adjacent to the steps and opposite the west entrance of the school. 15-year-old Michael Johnson was hit in the face, leg, and arm, but ran and escaped; 16-year-old Mark Taylor was shot in the chest, arms, and leg and fell to the ground, where he feigned death. The other three escaped uninjured.
Klebold walked down the steps toward the cafeteria. He came up to Kirklin, who was already wounded and lying on the ground, weakly calling for help. Klebold said, "Sure. I'll help you," then shot Kirklin in the face, critically wounding him. Daniel Rohrbough and Sean Graves had descended the staircase when Klebold and Harris' attention was diverted by the students on the grass; Graves—paralyzed beneath the waist—had crawled into the doorway of the cafeteria's west entrance and collapsed. Klebold shot Rohrbough, who was already fatally wounded by the shots previously fired by Harris, at close range through the upper left chest and then stepped over the injured Sean Graves to enter the cafeteria. Officials speculated that Klebold went to the cafeteria to check on the propane bombs. Harris shot down the steps at several students sitting near the cafeteria's entrance, severely wounding and partially paralyzing 17-year-old Anne-Marie Hochhalter as she tried to flee. Klebold came out of the cafeteria and went back up the stairs to join Harris.
They shot toward students standing close to a soccer field but did not hit anyone. They walked toward the west entrance, throwing pipe bombs, very few of which detonated. Meanwhile, inside the school, Patti Nielson, an art teacher, had noticed the commotion and walked toward the west entrance with a 17-year-old student, Brian Anderson. She had intended to walk outside to tell the two students to "Knock it off," thinking Klebold and Harris were either filming a video or pulling a student prank. As Anderson opened the first set of double doors, Harris and Klebold shot out the windows, injuring him with flying glass and hitting Nielson in the shoulder with shrapnel. Nielson stood and ran back down the hall into the library, alerting the students inside to the danger and telling them to get under desks and keep silent. Nielson dialed 9-1-1 and hid under the library's administrative counter. Anderson remained behind, caught between the exterior and interior doors.
At 11:22, the custodian called Deputy Neil Gardner, the assigned Student Resource Officer to Columbine, on the school radio, requesting assistance in the senior parking lot. The only paved route took him around the school to the east and south on Pierce Street, where, at 11:23 he heard on his police radio that a female was down, and assumed she had been struck by a car. While exiting his patrol car in the Senior lot at 11:24, he heard another call on the school radio, "Neil, there's a shooter in the school". Harris, at the west entrance, immediately turned and fired ten shots from his carbine at Gardner, who was sixty yards away. As Harris reloaded his carbine, Gardner leaned over the top of his car and fired four rounds at Harris from his service pistol. Harris ducked back behind the building, and Gardner momentarily believed that he had hit him. Harris then reemerged and fired at least four more rounds at Gardner (which missed and struck two parked cars), before retreating into the building. No one was hit during the exchange of gunfire. Gardner was not wearing his prescription eyeglasses and was unable to hit the shooters.
Thus, five minutes after the shooting started, and two minutes after the first radio call, Gardner had engaged in a gunfight with one of the student shooters. There were already two students dead and ten wounded. Gardner reported on his police radio, "Shots in the building. I need someone in the south lot with me."
The gunfight distracted Harris and Klebold from the injured Brian Anderson. Anderson escaped to the library and hid inside an open staff break room. Back in the school, the duo moved along the main North Hallway, throwing pipe bombs and shooting at anyone they encountered. Klebold shot Stephanie Munson in the ankle, although she was able to walk out of the school. The pair then shot out the windows to the East Entrance of the school. After proceeding through the hall several times and shooting toward—and missing—any students they saw, Harris and Klebold went toward the west entrance and turned into the Library Hallway.
Deputy Paul Smoker, a motorcycle patrolman for the Jefferson County Sheriff's Office, was writing a traffic ticket north of the school when the "female down" call came in at 11:23, most likely referring to the already dead Rachel Scott. Taking the shortest route, he drove his motorcycle over grass between the athletic fields and headed toward the west entrance. When he saw Deputy Scott Taborsky following him in a patrol car, he abandoned his motorcycle for the safety of the car. The two deputies had begun to rescue two wounded students near the ball fields when another gunfight broke out at 11:26, as Harris returned to the double doors and again began shooting at Deputy Gardner, who returned fire. From the hilltop, Deputy Smoker fired three rounds from his pistol at Harris, who again retreated into the building. As before, no one was hit.
Inside the school, teacher Dave Sanders had successfully evacuated students from the cafeteria, where some of them went up a staircase leading to the second floor of the school. The stairs were located around the corner from the Library Hallway in the main South Hallway. By now, Harris and Klebold were inside the main hallway. Sanders and another student were down at the end of the hallway still trying to secure as much of the school as they could. As they ran, they encountered Harris and Klebold, who were approaching from the corner of the North Hallway. Sanders and the student turned and ran in the opposite direction. Harris and Klebold shot at them both, with Harris hitting Sanders twice in the chest but missing the student. The latter ran into a science classroom and warned everyone to hide. Klebold walked over towards Sanders, who had collapsed, to look for the student but returned to Harris up the North Hallway.
Sanders struggled toward the science area, and a teacher took him into a classroom where 30 students were located. They placed a sign in the window: "1 bleeding to death," in order to alert police and medical personnel of Sanders' location. Due to his knowledge of first aid, student Aaron Hancey was brought to the classroom from another by teachers despite the unfolding commotion. With the assistance of a fellow student named Kevin Starkey, and teacher Teresa Miller, Hancey administered first aid to Sanders for three hours; attempting to stem the blood loss using shirts from students in the room. Using a phone in the room, Miller and several students maintained contact with police outside the school. All the students in this room were evacuated safely.
As the shooting unfolded, Patti Nielson talked on the phone with emergency services, telling her story and urging students to take cover beneath desks. According to transcripts, her call was received by a 9-1-1 operator at 11:25:05 a.m. The time between the call being answered and the shooters entering the library was four minutes and ten seconds. Before entering, the shooters threw two bombs into the cafeteria, both of which exploded. They then threw another bomb into the Library Hallway; it exploded and damaged several lockers. At 11:29 a.m., Harris and Klebold entered the library, where a total of 52 students, two teachers and two librarians had concealed themselves.
Harris yelled, "Get up!" so loudly that he can be heard on Patti Nielson's 9-1-1 recording at 11:29:18. Staff and students hiding in the library exterior rooms later said they also heard the gunmen say: "All jocks stand up! We'll get the guys in white hats!" (Wearing a white baseball cap at Columbine was a tradition among sports team members, typically jocks.) When no one stood up in response, Harris said, "Fine, I'll start shooting anyway!" He fired his shotgun twice at a desk, not knowing that a student named Evan Todd was hiding beneath it. Todd was hit by wood splinters but was not seriously injured.
The shooters walked to the opposite side of the library, to two rows of computers. Todd hid behind the administrative counter. Kyle Velasquez, 16, was sitting at the north row of computers; police later said he had not hidden underneath the desk when Klebold and Harris had first entered the library, but had curled up under the computer table. Klebold shot and killed Velasquez, hitting him in the head and back. Klebold and Harris put down their ammunition-filled duffel bags at the south—or lower—row of computers and reloaded their weapons. They walked back toward the windows facing the outside staircase. Noticing police evacuating students outside the school, Harris said: "Let's go kill some cops." He and Klebold began to shoot out the windows in the direction of the police. Officers returned fire, and Harris and Klebold retreated from the windows; no one was injured.
After firing through the windows at evacuating students and the police, Klebold fired his shotgun at a nearby table, injuring three students: Patrick Ireland, Daniel Steepleton, and Makai Hall. He removed his trench coat. As Klebold fired at the three, Harris grabbed his shotgun and walked toward the lower row of computer desks, firing a single shot under the first desk without looking. He hit 14-year-old Steven Curnow with a mortal wound to the neck. Harris then shot under the adjacent computer desk, injuring 17-year-old Kacey Ruegsegger with a shot which passed completely through her right shoulder and hand, also grazing her neck and severing a major artery. When she started gasping in pain, Harris tersely stated, "Quit your bitching."
Harris walked over to the table across from the lower computer row, slapped the surface twice and knelt, saying "Peek-a-boo" to 17-year-old Cassie Bernall before shooting her once in the head, killing her instantly. Harris had been holding the shotgun with one hand at this point and the weapon hit his face in recoil, breaking his nose. Initial reports suggest that Harris asked Bernall "Do you believe in God?", to which she replied yes, before getting killed. However, three students who witnessed Bernall's death, including Emily Wyant, who had been hiding beneath the table with her, have testified that Bernall did not exchange words with Harris after his initial taunt, although Wyant stated Bernall had been praying prior to her murder.
After fatally shooting Bernall, Harris turned toward the next table, where Bree Pasquale sat next to the table rather than under it. Harris asked Pasquale if she wanted to die, and she responded with a plea for her life. Witnesses later reported that Harris seemed disoriented—possibly from the heavily bleeding wound to his nose. As Harris taunted Pasquale, Klebold noted Ireland trying to provide aid to Hall, who had suffered a wound to his knee. As Ireland tried to help Hall, his head rose above the table; Klebold shot him a second time, hitting him twice in the head and once in the foot. Ireland was knocked unconscious, but survived.
Klebold walked toward another set of tables, where he discovered 18-year-old Isaiah Shoels, 16-year-old Matthew Kechter and 16-year-old Craig Scott (the younger brother of Rachel Scott), hiding under one table. All three were popular athletes. Klebold tried to pull Shoels out from under the table. He called to Harris, referring to him by his online identity and shouting, "REB! There's a nigger over here!" Harris left Pasquale and joined him. According to witnesses, Klebold and Harris taunted Shoels for a few seconds, making derogatory racial comments. Harris knelt down and shot Shoels once in the chest at close range, killing him instantly. Klebold also knelt down and opened fire, hitting and killing Kechter. Harris then yelled; "Who's ready to die next?". Meanwhile, Scott was uninjured; he lay in the blood of his friends, feigning death. Harris turned and threw a CO2 bomb at the table where Hall, Steepleton, and Ireland were located. It landed on Steepleton's thigh, and Hall quickly threw it away.
Harris walked toward the bookcases between the west and center section of tables in the library. He jumped on one and shook it, then shot in an unknown direction within that general area. Klebold walked through the main area, past the first set of bookcases, the central desk area and a second set of bookcases into the east area. Harris walked from the bookcase he had shot from, past the central area to meet Klebold. The latter shot at a display case located next to the door, then turned and shot toward the closest table, hitting and injuring 17-year-old Mark Kintgen in the head and shoulder. He then turned toward the table to his left and fired, injuring 18-year-olds Lisa Kreutz and Valeen Schnurr with the same shotgun blast. Klebold then moved toward the same table and fired with the TEC-9, killing 18-year-old Lauren Townsend. At this point, the seriously injured Valeen Schnurr began screaming, "Oh my God, oh my God!" In response, Klebold asked Schnurr if she believed in the existence of God; when Schnurr replied she did, Klebold simply asked "Why?" before walking from the table.
Harris approached another table where two girls were hiding. He bent down to look at them and dismissed them as "pathetic". Harris then moved to another table where he fired twice, injuring 16-year-olds Nicole Nowlen and John Tomlin. When Tomlin attempted to move away from the table, Klebold kicked him. Harris then taunted Tomlin's attempt at escape before Klebold shot the youth repeatedly, killing him. Harris then walked back over to the other side of the table where Lauren Townsend lay dead. Behind the table, a 16-year-old girl named Kelly Fleming had, like Bree Pasquale, sat next to the table rather than beneath it due to a lack of space. Harris shot Fleming with his shotgun, hitting her in the back and killing her instantly. He shot at the table behind Fleming, hitting Townsend and Kreutz again, and wounding 18-year-old Jeanna Park. An autopsy later revealed that Townsend died from the earlier gunshots inflicted by Klebold.
The shooters moved to the center of the library, where they continued to reload their weapons at a table there. Harris noticed a student hiding nearby and asked him to identify himself. It was John Savage, an acquaintance of Klebold's, who had come to the library to study for a history test. Savage said his name, believing they were targeting only jocks (which he himself was not), in an attempt to save his life; he then asked Klebold what they were doing, to which he answered, "Oh, just killing people." Savage asked if they were going to kill him. Possibly because of a fire alarm, Klebold said, "What?" Savage asked again whether they were going to kill him. Klebold hesitated, then told him to leave. Savage fled immediately, and escaped through the library's main entrance.
After Savage had left, Harris turned and fired his carbine at the table directly north of where they had been, grazing the ear of 15-year-old Daniel Mauser. When Mauser fought back, shoving a chair at Harris, Harris fired again and hit Mauser in the face at close range, killing him. Both shooters moved south and fired randomly under another table, critically injuring two 17-year-olds, Jennifer Doyle and Austin Eubanks, and fatally wounding 17-year-old Corey DePooter. DePooter, the last to die in the massacre, at 11:35, was later credited with having kept his friends calm during the ordeal.
There were no further injuries after 11:35 a.m. They had killed 10 people in the library and wounded 12. Of the 56 library hostages, 34 remained unharmed. Investigators would later find that the shooters had enough ammunition to have killed them all.
At this point, several witnesses later said they heard Harris and Klebold comment that they no longer found a thrill in shooting their victims. Klebold was quoted as saying, "Maybe we should start knifing people, that might be more fun." (Both youths were equipped with knives.) They moved away from the table and went toward the library's main counter. Harris threw a Molotov cocktail toward the southwestern end of the library, but it failed to explode. Harris went around the east side of the counter and Klebold joined him from the west; they converged close to where Todd had moved after having been wounded. Harris and Klebold mocked Todd, who was wearing a white hat. When the shooters demanded to see his face, Todd partly lifted his hat so his face would remain obscured. When Klebold asked Todd to give him one reason why he should not kill him, Todd said: "I don't want trouble." Klebold said, "You [Todd] used to call me a fag. Who's a fag now?!" The shooters continued to taunt Todd and debated killing him, but they eventually walked away.
Harris's nose was bleeding heavily, which may have caused him to decide to leave the library. Klebold turned and fired a single shot into an open library staff break room, hitting a small television. Before they left, Klebold slammed a chair down on top of the computer terminal and several books on the library counter, directly above the bureau where Patti Nielson had hidden.
The two walked out of the library at 11:36 a.m., ending the hostage situation there. Cautiously, fearing the shooters' return, 34 uninjured and 10 injured survivors began to evacuate the library through the north door, which led to the sidewalk adjacent to the west entrance. Kacey Ruegsegger was evacuated from the library by Craig Scott. Had she not been evacuated at this point, Ruegsegger would likely have bled to death from her injuries. Patrick Ireland, unconscious, and Lisa Kreutz, unable to move, remained in the building. Patti Nielson joined Brian Anderson and the three library staff in the exterior break room, into which Klebold had earlier fired shots. They locked themselves in and remained there until they were freed, at approximately 3:30 p.m.
After leaving the library, Harris and Klebold entered the science area, where they threw a small fire bomb into an empty storage closet. It caused a fire, which was put out by a teacher hidden in an adjacent room. The duo proceeded toward the south hallway, where they shot into an empty science room. At approximately 11:44 a.m., Harris and Klebold were captured on the school security cameras as they re-entered the cafeteria. The recording shows Harris kneeling on the landing and firing a single shot toward one of the propane bombs he and Klebold had earlier left in the cafeteria, in an unsuccessful attempt to detonate it. He took a sip from one of the drinks left behind as Klebold approached the propane bomb and examined it. Klebold lit a Molotov cocktail and threw it at the propane bomb. As the two left the cafeteria, the Molotov cocktail exploded, partially detonating one of the propane bombs at 11:46 a.m. Two minutes later, approximately one gallon of fuel ignited in the same vicinity, causing a fire that was extinguished by the fire sprinklers.
After leaving the cafeteria, the duo returned to the main north and south hallways of the school, shooting aimlessly. Harris and Klebold walked through the south hallway into the main office before returning to the north hallway. On several occasions, the pair looked through the windows of classroom doors, making eye contact with students hidden inside, but neither Harris nor Klebold tried to enter any of the rooms. They even reloaded their firearms close by the room that Dave Sanders was in. After leaving the main office, Harris and Klebold walked toward a bathroom, where they taunted students hidden inside, making such comments as: "We know you're in there" and "Let's kill anyone we find in here." Neither attempted to enter the bathroom. At 11:55 a.m., the two returned to the cafeteria, where they briefly entered the school kitchen. They returned up the staircase and into the south hallway at 11:58 a.m.
At 12:02 p.m., Harris and Klebold reentered the library, which was empty of surviving students except for the unconscious Patrick Ireland and the injured Lisa Kreutz. Once inside, they shot through the west windows at police, who returned fire. No individual was injured in this exchange.
At approximately 12:08 p.m., 32 minutes after they left the library, Dylan and Eric died next to each other. Both had committed suicide: Harris by firing his shotgun through the roof of his mouth; Klebold by shooting himself in the left temple with his TEC-9 semi-automatic handgun. It is widely believed that Patti Nielson overheard Harris and Klebold suddenly shout "One! Two! Three!" in unison, just before a loud boom, due to an article by The Rocky Mountain News. However, Patti Nielson has stated that she at no time has ever spoken with either of the writers of the article.
Patrick Ireland had regained and lost consciousness several times after being shot by Klebold. He crawled to the library windows where, at 2:38 p.m., he stretched out the window, intending to fall into the arms of two SWAT team members standing on the roof of an emergency vehicle, but instead falling directly onto the vehicle's roof in a pool of blood. They were later criticized for allowing Ireland to drop more than seven feet to the ground while doing nothing to try to ensure he could be lowered to the ground safely or break his fall. Eighteen-year-old Lisa Kreutz, shot in the shoulder, arms, hand, and thigh, remained in the library. In a subsequent interview, she recalled hearing a comment such as, "You in the library," around the time of Eric Harris and Dylan Klebold's suicides. Kreutz lay in the library, keeping track of time by the sound of the school's bells until police arrived. She had tried to move but became light-headed. She was finally evacuated at 3:22 p.m., along with Patti Nielson, Brian Anderson and the three library staff who had hidden in the break room.
By noon, SWAT teams were stationed outside the school, and ambulances started taking the wounded to local hospitals. Meanwhile, families of students and staff were asked to gather at nearby Leawood Elementary School to await information.
A call for additional ammunition for police officers in case of a shootout came at 12:20 p.m. The killers had ceased shooting just minutes earlier. Authorities reported pipe bombs by 1:00 p.m., and two SWAT teams entered the school at 1:09 p.m., moving from classroom to classroom, discovering hidden students and faculty. All students, teachers, and school employees were taken away, questioned, and offered medical care in small holding areas before being bussed to meet with their family members at Leawood Elementary. By 3:00 p.m., Dave Sanders had died of his injuries before SWAT officers could take him to get medical care. He was the only teacher to die in the shooting. Officials found the bodies in the library by 3:30 p.m.
By 4:00 p.m., the sheriff made an initial estimate of 25 dead students and teachers. The estimate was ten over the true count, but close to the total count of wounded students. He said that police officers were searching the bodies of Harris and Klebold. At 4:30 p.m. the school was declared safe. At 5:30 p.m., additional officers were called in, as more explosives were found in the parking lot and on the roof. By 6:15 p.m., officials had found a bomb in Klebold's car in the parking lot. The sheriff decided to mark the entire school as a crime scene. Thirteen of the dead, including the shooters, were still inside the school at the time. At 10:40 p.m., a member of the bomb squad, who was attempting to dispose of an un-detonated pipe bomb, accidentally lit a striking match attached to the bomb by brushing it against the wall of the ordnance disposal trailer. The bomb detonated inside the trailer but no one was injured.
The total count of deaths was 12 students and one teacher; 20 students and one teacher were injured as a result of the shootings. Three more victims were injured indirectly as they tried to escape the school. Harris and Klebold are thought to have committed suicide about 49 minutes after they started the massacre.
A total of 188 rounds of ammunition were fired by the perpetrators during the massacre (67 by Klebold and 121 by Harris). Additionally, law enforcement officers fired a total of 141 rounds during exchanges of gunfire with the shooters.
On April 21, bomb squads combed the high school. At 10:00 a.m., the bomb squad declared the building safe for officials to enter. By 11:30 a.m., a spokesman of the sheriff declared the investigation underway. Thirteen of the bodies were still inside the high school as investigators photographed the building.
At 2:30 p.m., a press conference was held by Jefferson County District Attorney David Thomas and Sheriff John Stone, at which they said that they suspected others had helped plan the shooting. Formal identification of the dead had not yet taken place, but families of the children thought to have been killed had been notified. Throughout the late afternoon and early evening, the bodies were gradually removed from the school and taken to the Jefferson County Coroner's Office to be identified and autopsied. By 5:00 p.m., the names of many of the dead were known. An official statement was released, saying there were 15 confirmed deaths and 27 injuries related to the massacre.
On April 30, high-ranking officials of Jefferson County and the Jefferson County Sheriff's Office met to decide if they should reveal that Michael Guerra, a Sheriff's Office detective, had drafted an affidavit for a search warrant of Harris's residence more than a year before the shootings, based on his previous investigation of Harris's website and activities. They decided not to disclose this information at a press conference held on April 30, nor did they mention it in any other way. Over the next two years, Guerra's original draft and investigative file documents were lost. Their loss was termed "troubling" by a grand jury convened after the file's existence was reported in April 2001.
In the months following the shooting, considerable media attention focused upon Cassie Bernall, who had been killed by Harris in the library and who Harris was reported to have asked, "Do you believe in God?" immediately prior to her murder. Bernall was reported to have responded "Yes" to this question before her murder. Emily Wyant, the closest living witness to Bernall's death, denied that Bernall and Harris had such an exchange.
Survivor Valeen Schnurr claims that she was the one questioned as to her belief in God by Harris. Joshua Lapp thought Bernall had been queried about her belief, but was unable to correctly point out where Bernall was located, and was closer to Schnurr during the shootings. Another witness, Craig Scott, whose sister Rachel Scott was also portrayed as a Christian martyr, claimed that the discussion was with Bernall. When asked to indicate where the conversation had been coming from, he pointed to where Schnurr was shot.
In the aftermath, speculation occurred about the killers' motivation and whether the murders could have been prevented. Unlike many previous school shootings, both shooters committed suicide, which made the massacre particularly difficult to assess.
In their investigation into how Harris and Klebold had acquired their firearms, police learned they had acquired one through a friend, Mark Manes. He and Philip Duran, who had introduced the duo to him, were eventually prosecuted for their roles in supplying guns to Harris and Klebold. Each was charged with supplying a handgun to a minor and possession of a sawed-off shotgun. Manes and Duran were sentenced to a total of six years and four-and-a-half years in prison, respectively.
The link between bullying and school violence has attracted increasing attention since the 1999 attack at Columbine High School. Both of the shooters were classified as gifted children who had allegedly been victims of bullying for four years. According to Brooks Brown, Klebold and Harris were the most ostracized students in the entire school, and even many of those close to them regarded the two as "the losers of the losers". Klebold is known to have remarked to his father of his hatred of the jock culture at Columbine, adding that Harris in particular had been victimized by this social group. In this remark, Klebold had stated, "They sure give Eric hell." On another occasion just weeks before the massacre, both Harris and Klebold had been confronted by a group of youths at the school—all members of the football team—who had sprayed them with ketchup and mustard while referring to the pair as "faggots" and "queers".
A year after the massacre, an analysis by officials at the U.S. Secret Service of 37 premeditated school shootings found that bullying, which some of the shooters described "in terms that approached torment", played the major role in more than two-thirds of the attacks. A similar theory was expounded by Brooks Brown in his book on the massacre; he noted that teachers commonly looked the other way when confronted with bullying, and that whenever Klebold and Harris were the recipients of such incidents from the jocks at Columbine, they would make statements such as: "Don't worry, man. It happens all the time!" if anyone expressed shock or surprise.
Early stories following the shootings charged that school administrators and teachers at Columbine had long condoned a climate of bullying by the so-called jocks or athletes, allowing an atmosphere of intimidation and resentment to fester. Critics said this could have contributed to triggering the perpetrators' extreme violence. Reportedly, homophobic remarks were directed at Klebold and Harris.
One author has strongly disputed the theory of "revenge for bullying" as a motivation for the actions of Harris and Klebold. David Cullen, author of the 2009 book Columbine, while acknowledging the pervasiveness of bullying in high schools including Columbine, has claimed that the two were not victims of bullying. Cullen said that Harris was more often the perpetrator than victim of bullying.
In July 1999, the FBI convened a major summit on school shooters in Leesburg, Virginia. Attending were psychologists, psychiatrists, and representatives from recent school shootings, including a large Columbine contingent. Attorney General Janet Reno attended. The FBI eventually published a major report on school shooters, though it did not pinpoint the causes of any individual case.
On the fifth anniversary of Columbine, the FBI's lead Columbine investigator and several psychiatrists published their conclusions in a news article. These conclusions stated Harris was a clinical psychopath, whereas Klebold was depressive. Harris had been the mastermind, having a messianic-level superiority complex, and had hoped to demonstrate his superiority to the world, whereas Klebold, having repeatedly documented his desires to commit suicide in his diaries—particularly due to his lack of success with women—had primarily participated in the massacre as a means to simply end his life. Dr. Dwayne Fuselier, the supervisor in charge of the Columbine investigation, would later remark: "I believe Eric went to the school to kill and didn't care if he died, while Dylan wanted to die and didn't care if others died as well." Klebold's final remark in the videotape he and Harris made shortly before their attack upon Columbine High School is a resigned statement made as he glances away from the camera: "Just know I'm going to a better place. I didn't like life too much."
The attack was the culmination of more than a year of planning, firearms acquisition, and bomb building. Harris's journals, in particular, show methodical preparation over a long period of time, including several experimental bomb detonations. By comparison, the journals Klebold populated initially contained few references to violence (although from January 1999 onward references to violence would become more frequent). By far the most prevalent theme in Klebold's journals is his private despair at his lack of success with women, which he refers to as an "infinite sadness."
For prior behavioral issues, Harris had been prescribed the SSRI antidepressant fluvoxamine; toxicology reports confirmed that Harris had fluvoxamine in his bloodstream at the time of the shootings. Klebold had no medications in his system.
Both Harris and Klebold were fans of video games such as Doom, Wolfenstein 3D, Duke Nukem, and Quake. Harris often created levels for Doom that were widely distributed; these can still be found on the Internet as the Harris levels. Rumors that the layout of these levels resembled that of Columbine High School circulated, but appear to be untrue. Harris spent a great deal of time creating another large mod, named Tier, calling it his "life's work." The mod was uploaded to the Columbine school computer and to AOL shortly before the attack, but appears to have been lost. One researcher argued that it is almost certain the Tier mod included a mock-up of Columbine High School.
Parents of some of the victims filed several unsuccessful lawsuits against video game manufacturers. Harris and Klebold were fans of the movie Natural Born Killers, and used the film's acronym, NBK, as a code in their home videos and journals.
During and after the initial investigations, social cliques within high schools were widely discussed. One perception formed was that both Klebold and Harris had been isolated from their classmates, prompting feelings of helplessness, insecurity, and depression, as well as a strong need for attention. This concept has been questioned, as both Harris and Klebold had a close circle of friends and a wider informal social group.
In the weeks following the Columbine shootings, media reports about Harris and Klebold portrayed them as part of a gothic cult. An increased suspicion of goth subculture subsequently manifested. Harris and Klebold had initially been thought to be members of "The Trenchcoat Mafia"; an informal club within Columbine High School. Later, such characterizations were considered incorrect.
Blame for the shootings was directed on a number of metal or 'dark music' bands such as KMFDM and Rammstein. The majority of that blame was directed at Marilyn Manson and his eponymous band. After being linked by news outlets and pundits with sensationalist headlines such as "Killers Worshipped Rock Freak Manson" and "Devil-Worshipping Maniac Told Kids To Kill", many came to believe that Manson's music and imagery were, indeed, Harris and Klebold's sole motivation, despite later reports that the two were not fans.
In the immediate aftermath, the band canceled the remaining North American dates of their Rock Is Dead Tour out of respect for the victims, while steadfastly maintaining that music, movies, books or video games were not to blame. Manson stated:
|“||The [news] media has unfairly scapegoated the music industry and so-called Goth kids and has speculated, with no basis in truth, that artists like myself are in some way to blame. This tragedy was a product of ignorance, hatred and an access to guns. I hope the [news] media's irresponsible finger-pointing doesn't create more discrimination against kids who look different.||”|
On May 1, 1999, Manson expanded his rebuttal to the accusations leveled at him and his band in his Rolling Stone magazine op-ed piece, "Columbine: Whose Fault Is It?" He castigated the ensuing hysteria and moral panic and criticized the news media for their irresponsible coverage; he chastised America's habit of hanging blame on scapegoats to escape responsibility. Columbine and America's fixation on a culture of guns, blame, and "celebrity by death" was further explored in the group's 2000 album Holy Wood.
In 2002, Manson appeared in Michael Moore's documentary, Bowling for Columbine; his appearance was filmed during the band's first show in Denver since the shooting. When Moore asked Manson what he would have said to the students at Columbine, he replied, "I wouldn't say a single word to them. I would listen to what they have to say and that's what no one did."
Nick Turse ascribed a revolutionary motive to the actions of Harris and Klebold. He wrote, "Who would not concede that terrorizing the American machine, at the very site where it exerts its most powerful influence, is a truly revolutionary task? To be inarticulate about your goals, even to not understand them, does not negate their existence. Approve or disapprove of their methods, vilify them as miscreants, but don't dare disregard these modern radicals as anything less than the latest incarnation of disaffected insurgents waging the ongoing American revolution." Historian David Farber of Temple University wrote that Turse's assertion "only makes sense in an academic culture in which transgression is by definition political and in which any rage against society can be considered radical."
A United States Secret Service study concluded that schools were placing false hope in physical security, when they should be paying more attention to the pre-attack behaviors of students. Zero-tolerance policies and metal detectors "are unlikely to be helpful," the Secret Service researchers found. The researchers focused on questions concerning the reliance on SWAT teams when most attacks are over before police arrive, profiling of students who show warning signs in the absence of a definitive profile, expulsion of students for minor infractions when expulsion is the spark that push some to return to school with a gun, buying software not based on school shooting studies to evaluate threats although killers rarely make direct threats, and reliance on metal detectors and police officers in schools when shooters often make no effort to conceal their weapons.
In May 2002, the Secret Service published a report that examined 37 U.S. school shootings. They had the following findings:
Following the Columbine shooting, schools across the United States instituted new security measures such as see-through backpacks, metal detectors, school uniforms, and security guards. Some schools implemented school door numbering to improve public safety response. Several schools throughout the country resorted to requiring students to wear computer-generated IDs. At the same time, police departments reassessed their tactics and now train for Columbine-like situations after criticism over the slow response and progress of the SWAT teams during the shooting.
In response to expressed concerns over the causes of the Columbine High School massacre and other school shootings, some schools renewed existing anti-bullying policies, in addition to adopting a zero tolerance approach to possession of weapons and threatening behavior by students. Despite the Columbine incident, several social science experts feel the zero tolerance approach adopted in schools has been implemented too harshly, with unintended consequences creating other problems.
One significant change to police tactics following Columbine is the introduction of the Immediate Action Rapid Deployment tactic, used in situations with an active shooter. Police followed the traditional tactic at Columbine: surround the building, set up a perimeter, and contain the damage. That approach has been replaced by a tactic that takes into account the presence of an active shooter whose interest is to kill, not to take hostages. This tactic calls for a four-person team to advance into the site of any ongoing shooting, optimally a diamond-shaped wedge, but even with just a single officer if more are not available. Police officers using this tactic are trained to move toward the sound of gunfire and neutralize the shooter as quickly as possible. Their goal is to stop the shooter at all costs; they are to walk past wounded victims, as the aim is to prevent the shooter from killing or wounding more. David Cullen, author of Columbine, has stated: "The active protocol has proved successful at numerous shootings during the past decade. At Virginia Tech alone, it probably saved dozens of lives."
The shooting resulted in calls for more gun control measures. In 2000 federal and state legislation was introduced that would require safety locks on firearms as well as ban the importation of high-capacity ammunition magazines. Though laws were passed that made it a crime to buy guns for criminals and minors, there was considerable controversy over legislation pertaining to background checks at gun shows. There was concern in the gun lobby over restrictions on Second Amendment rights in the United States. In 2001, K-Mart, which had sold ammunition to the shooters, announced it would no longer sell handgun ammunition. This action was encouraged by the award-winning 2002 documentary Bowling for Columbine, written and directed by Michael Moore.
A permanent memorial "to honor and remember the victims of the April 20, 1999 shootings at Columbine High School" was dedicated on September 21, 2007, in Clement Park, a meadow adjacent to the school where impromptu memorials were held in the days following the shooting. The memorial fund raised $1.5 million in donations over eight years of planning.
Since the shooting, "Columbine" or "the Columbine incident" has become a euphemism for a school shooting. Charles Andrew Williams, the Santana High School shooter, reportedly told his friends that he was going to "pull a Columbine," though none of them took him seriously. Many foiled school shooting plots mentioned Columbine and the desire to "outdo Harris and Klebold." Convicted students Brian Draper and Torey Adamcik of Pocatello High School in Idaho, who murdered their classmate Cassie Jo Stoddart, mentioned Harris and Klebold in their homemade videos, and were reportedly planning a "Columbine-like" shooting.
In a self-made video recording posted by Seung-Hui Cho to the news media immediately prior to his committing the Virginia Tech shootings, Cho referred the Columbine massacre in an apparent reference to his motivation for his own acts. In the recording, he also referred to Harris and Klebold as being "martyrs."
Since the advent of online social media, a fandom for shooters Harris and Klebold has had a documented presence on social media sites, especially Tumblr. Fans of Harris and Klebold referred to themselves "Columbiners." The group gained widespread media attention in February 2015 after three of its members conspired to commit a mass shooting at a Halifax mall on Valentine's Day. An article published in 2015 in the Journal of Transformative Works, a scholarly journal which focuses on the sociology of fandoms, noted that Columbiners were not fundamentally functionally different from more mainstream fandoms. Columbiners create fan art and fan fiction, as well as having a scholarly interest in the shooting.
The Columbine shootings influenced subsequent school shootings.
In 2009 sociologist Ralph Larkin of the John Jay College of Criminal Justice at City University of New York wrote that Harris and Klebold established a script for subsequent school shootings. Larkin examined twelve major school shootings in the United States in the eight years after Columbine and found that in eight of those, "the shooters made explicit reference to Harris and Klebold." Larkin concluded:
Harris and Klebold committed their rampage shooting as an overtly political act in the name of oppressed students victimized by their peers. Numerous post-Columbine rampage shooters referred directly to Columbine as their inspiration; others attempted to supersede the Columbine shootings in body count. ... The Columbine shootings redefined such acts not merely as revenge but as a means of protest of bullying, intimidation, social isolation, and public rituals of humiliation.
In 2012 sociologist Nathalie E. Paton of the National Center for Scientific Research in Paris analyzed the online videos created by post-Columbine school shooting perpetrators. A recurring set of motifs was found, including self-portraits with firearms in which the perpetrator points his gun "at the camera, then at his own temple, and then spreads his arms wide with a gun in each hand; the closeup" and "the wave goodbye at the end," as well as explicit statements of admiration and identification with previous perpetrators. Paton said the videos serve the perpetrators by distinguishing themselves from their classmates and associating themselves with the previous perpetrators.
A 2014 investigation by ABC News identified "at least 17 attacks and another 36 alleged plots or serious threats against schools since the assault on Columbine High School that can be tied to the 1999 massacre." Ties identified by ABC News included online research by the perpetrators into the Columbine shooting, clipping news coverage and images of Columbine, explicit statements of admiration of Harris and Klebold, such as writings in journals and on social media, in video posts, and in police interviews, timing planned to an anniversary of Columbine, plans to exceed the Columbine victim counts, and other ties.
A 2015 investigation by CNN identified "more than 40 people...charged with Columbine-style plots." According to psychiatrist E. Fuller Torrey of the Treatment Advocacy Center, a legacy of the Columbine shootings is its "allure to disaffected youth."
In 2015 journalist Malcolm Gladwell writing in The New Yorker magazine proposed a threshold model of school shootings in which Harris and Klebold were the triggering actors in "a slow-motion, ever-evolving riot, in which each new participant's action makes sense in reaction to and in combination with those who came before."
After the massacre, many survivors and relatives of deceased victims filed lawsuits. Under Colorado state law at the time, the maximum a family could receive in a lawsuit against a government agency was $600,000. Most cases against the Jefferson County police department and school district were dismissed by the federal court on the grounds of government immunity. However, the case against the sheriff's office regarding the death of teacher Dave Sanders was not dismissed due to the police preventing paramedics from going to his aid for hours after they knew Harris and Klebold were dead. The case was settled out of court in August 2002 for $1,500,000.
In April 2001, the families of more than 30 victims received a $2,538,000 settlement in their case against the families of Eric Harris, Dylan Klebold, Mark Manes, and Phillip Duran. Under the terms of the settlement, the Harrises and the Klebolds contributed $1,568,000 through their homeowners' policies, with another $32,000 set aside for future claims; the Manes contributed $720,000, with another $80,000 set aside for future claims; and the Durans contributed $250,000, with an additional $50,000 available for future claims. The family of Isaiah Shoels, the only African-American victim, rejected this settlement, but in June 2003 were ordered by a judge to accept a $366,000 settlement in their $250-million lawsuit against the shooters' families. In August 2003, the families of victims Daniel Rohrbough, Kelly Fleming, Matt Kechter, Lauren Townsend, and Kyle Velasquez received undisclosed settlements in a wrongful death suit against the Harrises and Klebolds.
His message reflected what many experts say was the dominant one from law enforcement in the wake of the shootings in Columbine.
After the events of the Columbine school massacre, Pennsylvanian Judge Ciavarella took a tough stance on juveniles with the zero tolerance policy.
But what if the way to explain the school-shooting epidemic is to go back and use the Granovetterian model—to think of it as a slow-motion, ever-evolving riot, in which each new participant’s action makes sense in reaction to and in combination with those who came before?
The suspects are almost always white male teenagers who have studied the Colorado high school massacre or cite the killers as inspiration. In the 16 years since the attack in Littleton, Colorado, more than 40 people have been charged with Columbine-style plots, according to searches of news accounts. Of those, more than a half dozen have come since LaDue's arrest in April 2014. Perhaps the most lasting legacy of Columbine, says Dr. E. Fuller Torrey, is its allure to disaffected youth.
Instead of seeing school shootings as isolated incidents, Gladwell offers a helpful analogy. "What if the way to explain the school-shooting epidemic is...to think of it as a slow-motion, ever-evolving riot, in which each new participant's action makes sense in reaction to and in combination with those who came before?"
