On April 20, 1999, two boys left an indelible stamp on the American psyche. Their goal was simple: to blow up their school, Oklahoma-City style, and to leave "a lasting impression on the world." Their bombs failed, but the ensuing shooting defined a new era of school violence-irrevocably branding every subsequent shooting "another Columbine." When we think of Columbine, we think of the Trench Coat Mafia; we think of Cassie Bernall, the girl we thought professed her faith before she was shot; and we think of the boy pulling himself out of a school window -- the whole world was watching him. Now, in a riveting piece of journalism nearly ten years in the making, comes the story none of us knew. In this revelatory book, Dave Cullen has delivered a profile of teenage killers that goes to the heart of psychopathology. He lays bare the callous brutality of mastermind Eric Harris, and the quavering, suicidal Dylan Klebold, who went to prom three days earlier and obsessed about love in his journal. The result is an astonishing account of two good students with lots of friends, who came to stockpile a basement cache of weapons, to record their raging hatred, and to manipulate every adult who got in their way. They left signs everywhere, described by Cullen with a keen investigative eye and psychological acumen. Drawing on hundreds of interviews, thousands of pages of police files, FBI psychologists, and the boy's tapes and diaries, he gives the first complete account of the Columbine tragedy. In the tradition of HELTER SKELTER and IN COLD BLOOD, COLUMBINE is destined to be a classic. A close-up portrait of hatred, a community rendered helpless, and the police blunders and cover-ups, it is a compelling and utterly human portrait of two killers-an unforgettable cautionary tale for our times.
A glimpse inside

Cullen systematically dismantles the most persistent myths about Columbine: that the killers were bullied outcasts, that they targeted specific groups like jocks or Christians, and that the so-called 'Trench Coat Mafia' was a driving force. Instead, he reveals how these narratives took hold in the chaos and confusion, fueled by media errors and public fear. The book challenges readers to question easy explanations and to recognize how misinformation can shape collective memory.
Drawing on journals, police reports, and psychological analyses, Cullen paints a nuanced portrait of Eric Harris and Dylan Klebold. Harris emerges as a textbook psychopath—charming, manipulative, and remorseless—while Klebold is depicted as a depressive, suicidal teenager swept up in Harris’s grandiose plans. This distinction is crucial to understanding their motives, which were less about revenge and more about destruction for its own sake.
