The diary, found in the home of one of the gunmen, contains a detailed timeline of events beginning in April 1998. The diary reveals that the killers picked a time when the largest number of students would be in the school cafeteria, that they planned to burn the school down and that the massacre was intentionally timed to coincide with AdolfHitler's birth date, April 20. It also revealed that the killers expected to die in the massacre, Stone said. They were going for a big kill. They also scattered more than 30 bombs and booby traps in the building, including a hidden 35-pound bomb made with a propane tank.
Investigators say the two finished the rampage by taking their own lives.
Your children who have ridiculed me, who have chosen not to accept me, who have treated me like I am not worth their time are dead. The message was sent after Harris was already dead. Davis said the FBI has concluded the note was not from Harris, but he said investigators stopped short of calling it a hoax and he could not rule out the possibility that it was sent by an unknown accomplice of the gunmen. The sheriff's department would not say in which home, Harris or Klebold's, the diary was found. Along with the diary, investigators found a detailed map of the school, with specific markings of areas that were poorly lighted and the best places to hide, Sheriff Stone said.
