Casper police have identified the suspect and victims in Friday's double murder case in Casper, Wyo.
Police say the suspect, 25-year-old Christopher Krumm of Vernon, Conn., shot his father, 56-year-old James Krumm, in the head with a bow and arrow in front of the father's computer science class at Casper College.
That was after officers say Christopher Krumm fatally stabbed his father's live-in girlfriend, 42-year-old Heidi Arnold, at their home not far from campus.
After shooting his father, Krumm allegedly stabbed himself, and then his father, killing them both.
"It's a troubling day," Casper Police Chief Chris Walsh said at a press conference. "This is a day you hope never comes into your community. And we've practices for these types of drills, but no one is ever ready for this to actually hit home."
Police have yet to determine a motive in the devastating attacks.
