Man killed father in bow-and-arrow attack in Wyoming

CASPER, Wyo. Ė Police released more details Saturday of a grisly murder-suicide at a Wyoming community college, saying a man shot his father in the head with a bow and arrow in front of a computer science class not long after fatally stabbing his fatherís live-in girlfriend at their home a couple miles away.

Computer science instructor James Krumm, 56, may have saved some of his studentsí lives Friday by giving them time to flee while trying to fend off his son, Christopher Krumm, 25, of Vernon, Conn., Casper Police Chief Chris Walsh said.

ďI can tell you the courage that was demonstrated by Mr. Krumm was absolutely without equal,Ē he said, adding that his actions could offer some measure of comfort to those affected by the killings.

He said police still were trying to figure out what motivated Christopher Krumm to attack his father and girlfriend, 42-year-old Heidi Arnold, a math instructor at the college. Arnold was found stabbed to death in front of the home she shared with James Krumm.

After shooting his father with the arrow, Christopher Krumm stabbed himself, then fatally stabbed his father in the chest in a struggle in the classroom, Walsh said.

Police arrived to find James Krumm dead and Christopher Krumm barely living; the younger Krumm died soon after students fled in a panic. Authorities locked down the campus for two hours.

Police began getting reports about the attack on Arnold soon after they responded by the dozen to the campus attack.

Christopher Krumm had smuggled the compound bow Ė a type much more powerful and effective for hunting than a simple, wooden bow Ė onto campus beneath a blanket, Walsh said.

He said Krumm also had two knives with him and the knife used was ďvery large.Ē

ďItís one of those situations you donít think is going to come home. Itís not going to happen here,Ē Walsh said.

Arnold died of multiple stab wounds. Her body was found in the gutter of her street. Evidence suggested much of the attack occurred outside the home, Walsh said.

Christopher Krumm had recently driven to Casper from Connecticut and had been staying at a local hotel. He had no significant history of encounters with police.

Police were uncertain what went awry in Christopher Krummís relationship with his father.

ďItís difficult to say. I donít think it was very close,Ē Walsh said.

Casper, population 56,000, is about 250 miles northwest of Denver and Wyomingís second-largest city after the state capital, Cheyenne. Wyomingites refer to Casper as the ďOil CityĒ because it is a hub of the stateís small oil industry.

Casper College is one of seven colleges in Wyomingís community college system. The campus was mostly quiet Saturday morning. A small group of drama students rehearsed a play in the school theater just across the street from the attack.

The building where the attack happened remained cordoned off by police tape that whipped in a brisk wind. A security guard let students back in, one at a time, to retrieve belongings theyíd left behind.

Andra Charter, a 20-year-old sophomore, emerged with a coffee mug. She recalled hearing screams outside her biology class before getting word about what had happened.

ďAs we were walking out, there was a girl screaming, ĎThereís somebody stabbing Mr. Krumm!íĒ Charter said.

No students were hurt in the attack.

Krumm was head of the collegeís computer science department. He was born north of London and also spent part of his childhood in Germany, according to the college website.

He held degrees from Casper College, a bachelorís degree and MBA from the University of Wyoming, and a masterís in computer science from Colorado State University.

Arnold held a masterís degree in mathematics from the University of Oregon and a bachelorís degree in math from University of California, Davis.

The college planned a candlelight vigil and memorial service Tuesday.
