Suicide notes tied to Casper College slaying

Investigators say they found two suicide notes written by a man who killed his father in front of a computer science class at a Wyoming community college. Court documents indicate an officer found one note in 25-year-old Christopher Krumm's car and a second note at Casper College. The documents don't specify exactly where the second note was found or the contents of either note. Police say Krumm barged into a classroom at the college Nov. 30 and shot his father, 56-year-old James Krumm, with an arrow in front of a handful of students. As the students fled, the Vernon, Conn., man stabbed his father with a knife, then killed himself. Before the campus slaying, the younger Krumm stabbed his father's girlfriend, 42-year-old Heidi Arnold, at the home she and James Krumm shared.
