CHEYENNE, Wyo. — A bizarre, rambling suicide note left behind by a man who police say killed his father in front of a handful of students in a Wyoming community college classroom extols eugenics and blames his father for the genes he said caused him to have Asperger's syndrome.
Christopher Krumm, 25, wrote that he was unable to keep a job, never had a love life and "always had to subsist as a sort of bottom feeder,"
The note confirmed a motive suggested by people close to Krumm in the immediate aftermath of the slayings.
"I am extremely bitter and frothing with hatred toward my father. I am resentful that my country did not castrate him," Krumm wrote.
The two-page, closely-spaced suicide note was entitled, "Tired of Having Asperger Syndrome; America Should Look to China."
A police statement Wednesday discouraged people from "making flash judgments" based on the content. Krumm had "self-diagnosed," the statement read, and there was no evidence he was ever officially identified with any mental or physical condition.
Casper police released the note Wednesday after The Associated Press filed a records request. Two copies of the letter were found soon after the Nov. 30 murder-suicide, police said.
The note praised eugenics – the practice of selecting people with certain traits for breeding and survival – and China for what Krumm described as that country's genetic, fiscal and cultural discipline.
"You should not have allowed my father to breed because he was genetically predispositioned toward having Asperger's Syndrome and put me at greatly increased risk for having it (and in fact I do). How could you hold his right to breed over my right not to be born?" Krumm wrote.
One copy was found in the Casper College classroom where police say Krumm shot his father, computer science instructor James Krumm, 56, in the head with an arrow using a high-powered bow. Authorities say he then stabbed his father and himself.
The students escaped unhurt and the campus was locked down for two hours.
Earlier that morning, police say, Christopher Krumm fatally stabbed his father's girlfriend, 42-year-old Casper College math instructor Heidi Arnold, at the home Arnold and James Krumm shared near campus.
Arnold's body was found in the street in front of the home.
An identical copy of the suicide note was found on the floor in the home's unfinished basement, Casper police Sgt. Deahn Amend said.
Asperger's is a mild form of autism not typically associated with violent behavior. People with Asperger's often have difficulty forming normal relationships with others.
Krumm wrote he was fired or had to quit four jobs.
"Despite having a Master's Degree in Electrical Engineering I have not been able to solve the novel problems I need to solve at work," he wrote.
Records show Krumm received the master's from Colorado School of Mines in 2009.
The note's mention of Asperger's was consistent with an aunt's and a neighbor's recollection that Krumm despaired at having the condition – and blamed his father for it.
Krumm most recently lived in a boarding house in Vernon, Conn. He traveled to Casper days before the murder-suicide.
Police in Connecticut also had reviewed writings of Krumm's, Amend said.
"It's my understanding they did have some they were looking through, but nothing that seemed to tie into what was going on here," she said.
Police were still awaiting autopsy results from the Natrona County coroner before they would consider the case closed. Autopsy results typically take six to eight weeks to be released, Amend said.
