A Vernon man who police said killed his father and his father's girlfriend in Wyoming and then killed himself had a pending application for a pistol permit in Connecticut at the time of the murder-suicide, police said on Monday.
On Friday, Vernon police searched the Grove Street rooming house where Christopher Krumm, 25, was living, at the request of police in Casper, Wyoming.
Police said Krumm traveled to central Wyoming and fatally stabbed Heidi Arnold, 42, before he shot his father, James Krumm, 56, in the head with a bow-and-arrow and then killed himself with a large knife.
Arnold was a math instructor at Casper College. Police said he stabbed her in front of the home she shared with his father.
He then went to the college and shot his father, a computer science instructor, with the bow-and-arrow, according to police.
Lt. Bill Meier said on Monday that Christopher Krumm lived in Vernon for only a couple months and applied for the pistol permit in Oct. 17.
He was fingerprinted and the application was still pending. No permit had been issued, police said. This was the only contact police had with him. When asked on Monday, Meier said the pistol permit application process typically takes about eight weeks.
According to the permit application, Christopher Krumm had lived in Springfield, Massachusetts before moving to Vernon.
No hazardous devices were found inside the Grove Street residence, police said. Police took paper records, a computer printer and they are being examined.
Police said they do not believe that Krumm had family in Vernon.
Casper Police Chief Chris Walsh said police still were trying to figure out what motivated Christopher Krumm to attack his father and girlfriend, Heidi Arnold.
Authorities in Wyoming are looking into Krumm's background, Vernon police said.
