CHEYENNE, Wyo. -- A relative of a man who killed his father in front of a computer science class at a Wyoming community college called him a "borderline genius" upset by the belief he had inherited Asperger's syndrome from his dad.
Barbara Nichols, an aunt of 25-year-old Christopher Krumm, says her nephew had trouble keeping jobs and blamed Asperger's.
Police say he shot 56-year-old James Krumm with an arrow and stabbed him in his Casper College classroom Friday. Around six students escaped unhurt, but earlier, Krumm fatally stabbed his father's girlfriend, 42-year-old Heidi Arnold, at their home.
Christopher Krumm fatally stabbed himself in the classroom.
Asperger's is a mild form of autism not normally associated with violent behaviour. Nichols says she only knew her nephew to be polite and amiable.
