The Platte Canyon High School hostage crisis was an incident of a hostage taking and shooting that occurred at Platte Canyon High School in Bailey, Colorado, on September 27, 2006. The gunman, 53-year-old Duane Roger Morrison entered the school building, claiming to be carrying a bomb. Morrison had been imprisoned in 1973 for larceny and possession of marijuana, and was arrested on a separate occasion for obstructing police in Littleton, Colorado. He was initially reported as a bearded 35-year-old man with a camouflage backpack and black hooded sweatshirt. Morrison took six female students hostage and sexually assaulted them, later releasing four. When police broke open the classroom`s door with explosives, Morrison opened fire with a semi-automatic pistol before shooting hostage Emily Keyes in the head. The other remaining hostage escaped unharmed, and paramedics confirmed that Morrison had committed suicide shortly before police were able to enter the classroom. Keyes was pronounced dead at 4:32 p.m. MDT (23:32 UTC) at Saint Anthony`s Hospital in Denver, Colorado after undergoing emergency surgery.
