Police investigate the scene of a homicide in front of a house on Hawthorne Ave. in Casper on Friday, Nov. 30, 2012, in Casper, Wyo. The body of the victim was visible by neighbors for several hours. A man wielding a sharp-edged weapon killed one person in this Casper neighborhood Friday before killing a male teacher and himself in front of students in a community college classroom, causing a campus-wide lockdown as authorities tried to piece together what happened.
