Chris Krumm killed his father with hunting bow, knife as students watched in horror.
Jim Krumm, the Casper College instructor killed by his son on Friday, fought back to allow roughly six students in his class to escape, police said.
Details emerging about Friday’s attack portray Krumm the hero after his 25-year-old son, Chris, burst into the classroom and shot his father in the head with a compound bow.
After students tried to help the wounded, 56-year-old computer science instructor, he instead fought his son so students could flee, NBC News said.
“The courage demonstrated by professor Krumm is absolutely without equal,” police Chief Chris Walsh said.
Chris Krumm then fatally stabbed his father with a large hunting knife while also cutting or stabbing himself, NBC said.
Police said Chris Krumm was still alive when they arrived, but died soon after of his injuries.
The harrowing incident began a few minutes earlier when Chris Krumm stabbed his father’s live-in girlfriend, Heidi Arnold.
