Columbine

The investigative book 'Columbine' was written by journalist Dave Cullen and published in 2009. Cullen spent nearly a decade researching the tragic 1999 high school massacre.

Dave Cullen's 2009 book famously debunks the myth that the shooters targeted specific groups like athletes, or that a student named Cassie Bernall was martyred for her faith. He establishes that the attack was intended to be a massive bombing, not a targeted shooting.

The book provides a detailed historical account of the 1999 Columbine High School massacre in Littleton, Colorado. It chronicles both the events of the day and its enduring cultural impact.

Dave Cullen spent approximately ten years researching and writing the book 'Columbine,' which was published in 2009. This extensive research allowed him to correct early media misconceptions about the tragedy.
