A Vernon resident drove to Casper, Wyo., and fatally stabbed a female college professor outside of her home before shooting his father with a bow and arrow and then killing himself in a Casper College classroom on Friday morning, police said.
Christopher Krumm, 25, who lived at 24 Grove St., Vernon, was the son of computer science instructor James Krumm, 56. Police said Chris Krumm shot his father in the head with an arrow in front of a room of four to six students before stabbing himself with a knife.
None of the students was injured.
Earlier, he stabbed Heidi Arnold, 42, James Krumm's girlfriend and an instructor at the college, about two miles away Friday, police said. She was stabbed multiple times and also had defense wounds, according to Casper Police Chief Chris Walsh.
Police say Arnold and James Krumm lived together at the Hawthorne Avenue home where Arnold was stabbed.
Christopher Krumm hid the bow and arrow and two knives under a blanket that he carried into the Wold Physical Science Center on campus before 9 a.m. Friday, according to Casper police.
He walked into room 325, where his father was teaching, and shot him in the head with the arrow, police said. James Krumm fell to the ground, then stood up and fought with his son, authorities said on Saturday.
Casper authorities believe Krumm drove to Wyoming from Connecticut earlier in the week and arrived on Thursday. It appears likely Krumm made the trip with the intention of committing the attack, Walsh said.
Krumm acted alone and had no significant criminal history, Walsh said. Police have found no indication that he threatened either of the victims before, or that they even knew he was back in Casper.
