The Vernon Police Department said a 25-year-old man from the town, who is believed to be responsible for killing his father and another woman in Wyoming, applied for a pistol permit before the murder.
Police said Christopher Krumm stabbed his father, Jim Krumm, 56, a computer science teacher and his father's girlfriend Heidi Arnold, 42, who was also a professor at Casper College, a Wyoming community college, on Friday morning.
According to police, Christopher Krumm first stabbed Arnold, who was his father's girlfriend, at the home he lived at with his father before going to the college.
Investigators said the 25-year-old then went to the school's campus and shot his father with a bow-and-arrow in front of a group of students in the Wold Physical Science Building.
Police said Jim Krumm tried to fight off his son while students escaped. Christopher Krumm then stabbed himself several times before fatally stabbing his father in the chest, police said.
Vernon police said Christopher Krumm had applied for a gun permit in October. The permit was still pending at the time of Friday's double murder.
"(Chris) Krumm was fingerprinted and his completed application was collected," said Vernon Police Lt. William Meier. "The application was still pending at the time of this incident and no permit had been issued to Krumm."
Vernon police along with the Hartford Bomb Squad searched Christopher Krumm's apartment on Friday night. No hazardous devices were found in the unit.
Detectives in Vernon seized some paper records, a computer printer and other items, which had been requested by Wyoming authorities.
The items are being examined, but police said "there does not appear to be any significant items seized from the apartment."
Any items of interest would be turned over to investigators in Wyoming.
Neighbors in Vernon told Eyewitness News that Christopher Krumm kept to himself, appeared to be anti-social, and told them he had Asperger's syndrome.
Police in Vernon said it is believed that Christopher Krumm lived at his Grove Street apartment for a few months. He was employed by Broadband Access Services as a groundsman and assisted linesman. He believed to quit his job on Tuesday.
Neighbors say it's hard to believe Christopher Krumm, with a masters in engineering, is responsible for a murderous rampage in Wyoming.
"I still cant believe I lived next door to him," said neighbor Kim Warren. "I mean, what makes a person crack like that?"
