DENVER –Officials have confirmed that the suspect involved in the murder-suicide attack at a central Wyoming community college Friday has connections to Colorado.

According to Karen Gilbert, a spokeswoman from the Colorado School of Mines, 25-year-old Chris Krumm, who shot and killed his father and his father's girlfriend Friday, graduated from the graduate program at Mines in 2009. FOX31 Denver learned that he was an electrical engineering student at the college.

The victims killed during the murder-suicide attack at a central Wyoming community college Friday were identified on Saturday.

According to the Casper Police Department, the victims were identified as 56-year-old James Krumm, and his girlfriend 42-year-old Heidi Arnold. Both victims were professors at Casper College.

 Chris Krumm was James Krumm’s 25-year-old son.

Police said Chris Krumm stabbed his father’s girlfriend to death outside of her home on Hawthorne Avenue, before driving to Casper College with a compound bow and arrow and two knives.

Officers said Chris Krumm entered his father’s classroom just after 9 a.m. at the World Physical Science building and shot his father in the head with an arrow, knocking him to the ground.
