Police say a Wyoming community college teacher James Krumm was a hero for fighting off his son on Friday, potentially saving the lives of six of his computer science students.
"I can tell you the courage that was demonstrated by Mr. Krumm was absolutely without equal," Casper Police Chief Chris Walsh said, according to The Associated Press.
On Friday, Christopher Krumm, 25, stabbed his father's girlfriend to death before driving to Casper College, where his father was teaching a class. He was equipped with a compound bow and arrow and two knives, which he carried into the building under a blanket.
When he entered the classroom, Christopher Krumm stood about four feet from his father, pulled back the bowstring and shot an arrow through his father's head, the Casper Tribune reported.
His father, James Krumm, 56, fell but got back up and struggled with his son, the Tribune reported.
That's when Christopher Krumm stabbed himself, then plunged the knife into his father's chest, killing him, Walsh said.
When police arrived, the elder Krumm had died and the younger was taking his final breaths.
Police believe that Christopher Krumm drove from Vernon, Conn., where he was living, and booked into a motel on the outskirts of town on Thursday, the day before the killings.
On the Casper College website, James Krumm described himself as a teacher born in London, England and partly raised in Germany. He started teaching at Casper College in 2002.
