Teen Thrill Killers.
A look at some of the most frightening murderers of all--teenagers who kill for the thrill of it. Thomas Koskovich murdered a pizza deliveryman just "to see what it felt like to kill." Kevin Foster and a group of high-school students with otherwise excellent records killed a music teacher, and Foster bragged about how cool it was to see the teacher's face blown off with a shotgun. And in Tacoma, Washington, eight boys aged 11-19 beat a young boy to death as if they were simply playing a game.
