STUTTGART, Germany -- German police said Friday there is no indication that the teenager who went on a killing rampage at a high school posted a warning before the attack.
Police spokesman Nikolaus Brenner reversed an initial report that a purported warning of the incident posted to a chat room had originated on the personal computer of the shooter, Tim Kretschmer, The New York Times reports.
Kretschmer, 17, killed 12 people at a high school in Wittenden along with an employee of a clinic and two people at a Volkswagen dealership Wednesday before turning the gun on himself.
Police said the teen had broken off a round of counseling for depression last year.
A search of his bedroom turned up violent computer games plus brutal videos and play weapons, said a spokesman for the Stuttgart prosecutor's office.
Kretschmer's parents could face criminal charges under German law for failing to secure the pistol their son used in the shootings, the Times said.
