CITRUS HEIGHTS (CBS13) – A bizarre classroom attack involving a bow and arrow left a college professor dead, and the other victim was a UC Davis graduate who grew up in Citrus Heights.
Heidi Arnold, 42, graduated from Del Campo High School in 1988. She was also an accomplished UC Davis graduate and ultimately ended up in Wyoming to teach at Casper College.
The community of Casper is still reeling from the gruesome and tragic murder of two college professors, Arnold and her boyfriend Jim Krumm, 56.
“This is a day you hope never comes into your community,” Casper Police Chief Chris Walsh said. “We have practiced for these types of drills, but no one is ever actually ready for this to hit home.”
Police say Jim’s son, 25-year-old Chris Krumm, went over to the couple’s home and stabbed Heidi to death Friday. They say he then barged into his father’s classroom a few miles away, shooting him with an arrow in the head right in front of his students.
Detectives say he then stabbed and killed himself.
Grant Wilson is the dean of the college’s School of Science. He said Heidi was a math teacher who could really relate to her students.
“They’d always been intimidated by math until they had Heidi for class and she made the material really accessible for them,” Wilson said.
“There’s a lot of anger, there’s a lot of ‘Why did this have to happen?’” he added.
Now, with just a week left in the semester, students and teachers are forced to deal with two sudden and horrific losses.
The math professor known for her love of travel, her work, and her students, Heidi forever left her mark on those who knew her.
“That positive attitude and approach to teaching is something we will all learn from,” Wilson said.
Investigators are still trying to determine a motive. A memorial for Heidi and Jim will be held Tuesday on campus.
