Authorities have identified the gunman who entered Platte Canyon High School Wednesday and took six students hostage as a 53-year-old Denver man, and say "he did traumatize and assault our children."
Park County Sheriff Fred Wegener says Duane R.-Morrison had at least a pistol and a revolver on him when his body was removed from Platte Canyon High School overnight.
But Wegener declined to discuss the contents of the backpack in which Morrison claimed to have a bomb.
He did say the attack itself was "sexual in nature."
Morrison had a criminal record that included arrests for larceny, marijuana possession and obstructing police.
Data from the Crime Information Center at the Colorado Bureau of Investigation shows arrests as early as 1973, but none for anything as violent as yesterday's four-hour stand-off that ended with two deaths.
Morrison killed himself after fatally shooting one hostage in the head. Wegener says Morrison apparently picked the classroom at random.
Morrison had been living out of his car, but had a Denver-area address.
His stepmother in Tulsa identified herself as Mrs. Bob Morrison, and said she had no record of him being in trouble before. She said Morrison's mother died 30, perhaps 35, years ago.
Wegener says Morrison had no known connections to the Bailey area, but the investigation is ongoing
Autopsies are scheduled Thursday on the bodies of Morrison and the student hostage he killed, 16-year-old Emily Keyes.
