Former 5280 contributor Dave Cullen will be interviewed in a CNN documentary airing this weekend:

The images are all too familiar – crude, homemade videos that reveal the face of madness: Cho Seung-Hui, the killer at Virginia Tech, and Eric Harris and Dylan Klebold, the teenage shooters at Columbine High School. Unfortunately, these grim self-portraits are revealed only after these killers committed their terrible acts of violence. CNN: Special Investigations Unit looks at how these killers and other criminally insane mass murderers--Jeffrey Dahmer, Ted Kaczynski--escaped detection for so long, and examines whether they could have been stopped. CNN: Special Investigations Unit – Criminally Insane, will premiere on Saturday, July 14, and Sunday, July 15, at 8 p.m. and 11 p.m. All times Eastern.

Way back in August 1999, Dave scored the first in-depth interview with Columbine principal Frank DeAngelis for 5280.
