Sidney, NY (WBNG Binghamton) A warrant led police to discover the bodies of a woman's husband and boyfriend.
New York State State Police said Debra Sundstrom, 48, of Walton, was originally a suspect in a larceny case.
They only discovered her dead husband and boyfriend after investigators went to question her.
Investigators showed up at 51-year-old Dominik Bosco's home on John Lockwood Road a week ago with a warrant for Sundstrom's arrest.
Sundstrom told investigators to wait when they knocked on her door. She then preceded to shoot a dog, set fire to the home and shoot herself in the head. The following day, Bosco's remains were found in the basement area of the burned out home.
State Police said he had been dead at least a few days, but haven't determined how he died.
It's also not clear if Sundstrom had been living there.
The long gun she used to kill herself belonged to Bosco's family.
While investigating the larceny, police had also been looking to talk to the whereabouts of Debra's husband, 49-year-old Randy Sundstrom.
"We tried speaking to a lot of people who were family members who hadn't been in touch with him in many years, so we weren't able to locate any family as to who had seen or talked to him in that length of time," said NYSP Lt. Erik Dauber. "That matter is still under investigation,"
State police used dogs to search the Sundstrom home on River Road. The dogs immediately "hit" on a barrel in the backyard.
Randy's remains were inside. They believe that he had been dead since 2010.
Debra Sundstrom is the primary suspect in the homicide, but police are following several other leads.
