Casper Police Chief Chris Walsh answers questions during a news conference, Saturday, Dec. 1, 2012, detailing Friday's killings at Casper College and Hawthorne Avenue. Walsh said Saturday that 25-year-old Christopher Krumm, of Vernon, Conn., first stabbed 42-year-old Heidi Arnold about two miles southwest of Casper College on Friday morning. Krumm then went to the college and shot his father, 56-year-old computer science instructor James Krumm, in the head with the bow-and-arrow in front of a group of students before stabbing himself with a large knife. Walsh says the younger Krumm smuggled the weapon into the classroom under a blanket. (AP Photo/The Casper Star-Tribune, Alan Rogers) MANDATORY CREDIT; TRIB.COM
