Dec 4, 2012 - By Mead Gruver, The Associated PressChristopher Krumm killed his father, a former Lander resident, and a Casper woman before committing suicide Friday.
A man who killed his father, a former Lander resident, in front of a computer science class at Casper College was a �borderline genius� upset by the belief he had inherited Asperger�s Syndrome from his dad, an aunt of the killer said Monday.
Christopher Krumm, 25, blamed Asperger�s for his trouble keeping jobs after he got a master�s degree in electrical engineering from Colorado School of Mines in 2009, said Barbara Nichols, of Bakersfield, Calif.
�Nice to be around. Never caused any trouble of any kind,� said Nichols, who�d briefly lived with her sister�s family in Casper in the early 1990s.
Asperger�s is a mild form of autism. Asperger�s is associated with difficulty making social connections but is not normally associated with predilection to violent behavior.
Krumm seemed normal to relatives as recently as three years ago, but then had a falling-out with his father. An uncle, Jon Sims, of Cheyenne, said he tried several times in recent years to reach his nephew by email, without success.
�As far as I know, he lived alone and had some social skill problems,� Sims said.
Sims and Nichols both said they didn�t know of any official diagnosis of Asperger�s, but that Krumm may have diagnosed himself. Nichols said James Krumm told her that his son blamed him for Asperger�s.
�He said �He hates me. He blames me for this Asperger�s,� � she said.
Police say Krumm shot 56-year-old James Krumm with an arrow and stabbed him in his Casper College classroom Friday. The six or so students in the computer science class escaped unhurt.
Earlier, Krumm fatally stabbed his father�s girlfriend, 42-year-old Heidi Arnold, at the home she and James Krumm shared in a quiet neighborhood about two miles from campus. Arnold was a math instructor at Casper College.
Christopher Krumm fatally stabbed himself in the classroom after attacking his father. Nobody saw the final moments of the struggle � all students were able to flee unhurt � but police say Christopher Krumm stabbed his father in the chest.
Police arrived to find James Krumm dead and Christopher Krumm breathing his last breaths; he died in the classroom. Authorities locked down the campus for two hours until they were reassured there were no other attackers.
Police said Krumm acted alone and that his motive was unclear. No suicide note was reported found.
Krumm had been living in an apartment house in Vernon, Conn., and drove to Casper a few days before the attack.
Nichols said she only knew her nephew to be polite and amiable. She said he was very close to his mother, Carol Krumm, who died of breast cancer in 2005.
Nichols said her nephew was friendly with his cousins but didn�t seem to have any other friends his own age growing up.
�He was always comfortable around adults, and I guess kids in his class seemed too immature for him,� Nichols said.
�I�m just real sad to lose him. I�m sad. I really loved him. It was hard losing my sister and now this. I wonder what�s next. But he was obviously a lost soul, and I hope he�s at peace now.�
