UCD Grad From Fair Oaks Killed by Boyfriend's Son in Wyoming

A Fair Oaks native who graduated from UC Davis was killed by her boyfriend's 25-year-old son in Wyoming last Friday.

Heidi Arnold, who graduated from Del Campo High in Fair Oaks in 1988, and her boyfriend James Krumm were, according to police, killed by Krumm's son Chris in Casper, Wyoming, according to the Wyoming Star-Tribune .

Arnold, who received a bachelors degree from UC Davis in 2001 before moving to Casper in 2003 to teach math, was killed at the couple's home, while Krumm was away at the college.

Police suspect much of the attack on Heidi took place outside the house. Chris (Krumm, the son) stabbed her multiple times. Authorities found signs of defensive wounds on her body.

She was barefoot and still dressed in pajamas.

It would have taken only minutes for Chris to drive from his father’s house to the campus.

He arrived at the Wold Physical Science Center with two knives and a compound bow hidden inside a blanket.

Krumm, who was a professor at Casper College, was killed in his classroom.

Chris Krumm stepped into the classroom and drew back the bowstring. His father, Casper College professor Jim Krumm, was close; maybe only four feet away. Chris fired a single arrow.

It struck his father in the side of the head, and traveled through to the other side.

Read about a memorial that was held for Arnold and Krumm in this Star-Tribune piece that was published Wednesday. The story describes Arnold as "the 'ultimate hippy chick,' a pacifist with a rebellious spirit who adored John Lennon, said speaker Maya Russell, a political science instructor and friend."
