Friendship Overview Harris and Klebold became friends while attending Ken Caryl Middle School. They entered Columbine High School in 1995 as a
freshman, shortly after the school had undergone a major
renovation and expansion. At Columbine High School, they formed a close-knit
friend group, with social activities including
bowling, shooting
pool,
carpooling, watching
films, and playing
video games together. After their
sophomore year of high school, however, Harris and Klebold were described as nearly inseparable. Detailed information about their private conversations remains limited: aside from the "Basement Tapes", for which only transcripts have been released, along with a brief audio clip recorded surreptitiously by a victim's father, few direct records are available. Judy Brown, mother of Brooks Brown, stated that she believed Harris was more emotionally dependent on Klebold, who was more widely liked among the student population. In his writings, however, Klebold expressed feelings of not being loved or accepted, which some sources suggest may have led him to seek validation from Harris.
Sue Klebold has stated that she believes her son's self-destructive tendencies, combined with Harris's anger, led the two to reinforce each other's behavior, resulting in what became an unhealthy dynamic.
Personalities Some peers described Harris as charismatic, while others described him as polite and likable. According to various accounts, he had many friends and played
midfield for a local
soccer team, the Colorado Rush, during his first two years of high school. Josh Swanson, a former teammate, said that Harris was a "solid" soccer player who greatly enjoyed the sport. By his
junior year, however, Harris was reported to be quick to anger and to make frequent threats against others. Classmates observed a change in his style of dress, noting that he shifted from
preppy attire to darker, cargo-style clothing. Harris reportedly boasted about his ability to
deceive others, stating in one recording that he could make anyone believe anything. Although some described Klebold as friendly and easygoing, many considered him shy and quiet. He was often fidgety and hesitant to engage with new people. Like Harris, observers noted a change in Klebold's behavior after junior year, becoming more short-tempered and prone to outbursts of anger. Prior to the shooting, he had been disciplined for
swearing at teachers, slamming classroom doors, and defacing a locker with a
homophobic slur.
Initial high school activity Computer use Amid a technological boom, Harris, Klebold, and their group of friends owned
personal computers, which allowed them to remain active on the
internet. They also connected their computers on a
private server to play
first-person shooter games together, including
Doom II and
Quake. In 1996, Harris began creating a set of
levels for
Doom II, which later infamously became known as the "Harris levels". The levels are downloadable over the internet through
Doom WADs. Harris maintained a significant online presence under the
handle "REB" (short for Rebel, a nod to the
mascot of Columbine High) and other aliases, including "Rebldomakr", "Rebdoomer", and "Rebdomine". Klebold went by the names "VoDKa" and "VoDkA", after the
alcoholic beverage and as a play on his initials. Harris operated various websites that hosted his
Doom and
Quake files, as well as information about the teams with whom he gamed online. These websites were shut down by
America Online hours after the shootings and preserved for the FBI. Harris was described as a good student and respectful towards teachers. Klebold was known to be intelligent, pursuing advanced coursework, though he was reportedly apathetic about paying attention in class and maintaining his grades. He and Harris, along with their friend Zack Heckler, were involved in
video and sound productions and worked as computer assistants, helping to maintain Columbine High School's network.
Early police reports During the early months of 1997, Harris, Klebold, and their friends engaged in acts of
mischief on weekends. These nighttime activities reportedly involved setting off
explosives, stealing street signs,
vandalizing the homes of classmates they disliked, and consuming
alcohol together afterwards. In his webpages, Harris referred to the acts as "rebel missions", summarizing his involvement in "mission logs." Shortly afterward, Harris briefly came to the attention of police following complaints of property damage in the neighborhood. Brooks Brown, who had previously been friendly with Harris, severed ties with him in February 1997 after Harris damaged Brown's car
windshield with a chunk of ice during an argument. In response, Brown informed Harris's parents of their son's secret alcohol collection and persuaded them to have Harris apologize in person to the Brown family for the windshield. Humiliated by the incident, Harris soon began posting
death threats to Brown on his website, writing, "All I want to do is kill and injure as many of you as I can, especially a few people. Like Brooks Brown." On August 7, 1997, an anonymous "concerned citizen" reported one of Harris's websites to the
Jefferson County Sheriff's Office for online threats against the Browns, who were subsequently notified. Months later, in March 1998, the Brown family followed up with police after finding out that Harris had posted instructions for building
pipe bombs on a separate website. It was later revealed in 2001 that, based on accounts from the Brown family and a report of an unexploded
plastic pipe bomb found on a
bike path approximately two miles from Columbine High School, Sheriff's detective Mike Guerra drafted an affidavit in April 1998 for a search warrant to be executed on the Harris household; however, the warrant was never submitted to a judge.
Burglary arrest and diversion On the night of January 30, 1998, Harris and Klebold broke into a parked van in a lot at Deer Creek Canyon Park and stole electronic equipment. Jefferson County Sheriff's Deputy Tim Walsh later noticed the two parked farther down the road near a park entrance. Because the park was closed at that time of night, Walsh approached them to investigate, and announced his presence as one of the boys prepared to move the stolen items into the trunk of Harris's car. After both were questioned about the origin of the equipment, Harris confessed to the theft. The two soon pleaded guilty to criminal mischief,
breaking and entering,
trespassing, and
theft. They were sentenced to participate in a
diversion program that included
victim restitution,
community service,
anger-management classes, and
counseling in exchange for the future
expungement of their
criminal records. During their March 1998 diversion intake, both Harris and Klebold were described as cooperative and left favorable impressions on
juvenile officers. On a form asking them to identify self-behavioral issues, Harris checked fourteen boxes, among them "anger", "depression", "
suicidal thoughts", and "
homicidal thoughts", while Klebold selected just two, "finances" and "jobs". According to his mother, Klebold attempted to justify the burglary by stating that the crime "was not against a person," but rather "a company," and that the incident was the reason "why people have insurance." Similarly, in a personal journal entry dated April 12, 1998, Harris wrote, "Isn't america supposed to be the land of the free? how come, If im free, I cant deprive some fucking dumbshit from his possessions If he leaves them sitting in the front seat of his fucking van in plain sight in the middle of fucking nowhere on a fri-fucking-day night?
Natural selection. Fucker should be shot.". Despite this entry, he submitted a letter that same month to the owner of the van, expressing regret for his actions. However, he also bragged about the robbery and sought to justify it in his personal diary. Klebold was accepted to several colleges for
computer science. After enrolling at the
University of Arizona for the 2000 academic year, Klebold and his parents visited
Tucson in late March 1999 to tour the campus and secure a
dormitory room. Harris, meanwhile, applied to join the
United States Marine Corps but was informally rejected on April 15, 1999, due to his use of
fluvoxamine, an
SSRI antidepressant prescribed as part of court-ordered anger-management therapy. On April 17, 1999, Klebold attended Columbine High School's senior
prom with a group of students that included his date, Robyn Anderson, and his close friend, Nate Dykeman. Harris had invited a girl to his house that night and later joined Klebold and the group at the prom
afterparty. While there, Klebold scheduled plans with Devon Adams and another friend to see
The Matrix at a movie theater on the evening of Wednesday, April 21. Numerous accounts indicate that Harris and Klebold appeared happy and looked forward to having plans beyond graduation. == Gathering materials ==
