"What's amazing is how much of Cullen's book still comes as a surprise . . . [Cullen's] nuanced dissection of the differences between Eric Harris and Dylan Klebold is first-rate."
— New York Times Book Review

The Rest of the Story
on this site

The sheer size of the Columbine evidence is overwhelming. And most of the early reporting on why it happened was wrong.

I culled through thousands of police files, pictures, journals, videos, interviews, 911 calls, crime scene photos, etc. As I organized the information, I decided to share my research online.

For this site, I compiled the most significant evidence and tried to make it easy to find. I hope this helps you navigate the maze of myths, distortions and the truth. Good luck on your search.
