CASPER, Wyo. (AP) — A Wyoming community college instructor killed in a grisly classroom murder-suicide is being hailed as a hero.

Police say he gave his students time to flee by distracting and fighting off his son after the younger man barged into his computer science class and shot him in the head with a high-powered bow and arrow.

The arrow severely wounded 56-year-old James Krumm, but he managed to wrestle with son Christopher Krumm, of Vernon, Conn., while students escaped the Casper College classroom Friday.

Christopher Krumm had just stabbed to death his father's live-in girlfriend at the couple's home two miles away.

When police arrived at the classroom after the bow-and-arrow attack, they found Christopher Krumm bleeding from self-inflicted knife wounds and taking his last breaths.

Police say James Krumm was also dead.
