(Scroll down for video) A man stormed a classroom at Wyoming Community College and killed his father with a bow and arrow in front of the entire class, according to police reports.

Police released more details Saturday in the gruesome murder-suicide in the Wyoming Community College, saying that a man shot his father in the head with a bow and arrow in front of the computer science class, not long after the man fatally stabbed his live-in girlfriend at his home a couple of miles away.

Computer instructor James Krumm, 56, saved some of the lives of his students on Friday by giving them time to flee while trying to fend off his son, Christopher Krumm, 25, of Vernon, Connecticut, police chief Chris Walsh said.

"I can say that the effort shown by Mr. Krumm was absolutely unparalleled," he said, adding that his actions could provide some measure of comfort to those affected by the murders.

Casper police said they were still trying to figure out what motivated Christopher Krumm to attack his father and his girlfriend, 42-year-old Heidi Arnold, a math teacher in college. Arnold was found stabbed to death in front of the house she shared with James Krumm.

After shooting his father with an arrow, Christopher Krumm fatally stabbed himself and then stabbed his father in the chest during a fight in class, Casper police said.
