Town of Triangle, NY (WBNG Binghamton) When Melissa Oney told her husband Larry she wanted a divorce, he decided to end their marriage of five years immediately by killing her and their 3-year-old daughter, Allison.
Deputies say Larry changed his mind, though, and decided to allow Melissa to live so she could witness the murder of their daughter, and remember it for the rest of her life.
The Broome County Sheriff's Office says it's been years since they've handled a domestic violence case of this magnitude.
Members of the investigating team provided details Monday about what happened Saturday inside 54 Old Catskill Turnpike.
They say Larry Oney threatened to kill both his wife and little Allison, and burn the house down.
Larry cut Melissa's Achilles tendon and bound her with neck-ties, but she was able to escape and drive down the road to dial 911.
Meanwhile, Larry barricaded himself in the family's home with his daughter, doused the contents in gasoline and fulfilled his promise to burn down the house.
When deputies arrived, gunshots were heard. By that time, the home was so engulfed in flames, crews could not enter.
"I think it was a very good response," said Broome County Sheriff David Harder. "All agencies responded immediately, as fast as they could to get out there. The rounds were going off as the house was burning. They thought maybe the subject inside was shooting at them. Even the fire chief took right to the ground when the rounds were going off," said Broome County Sheriff David Harder.
Those rounds were set off by the heat of the fire.
The bodies of both Larry and Allison were identified through DNA testing and dental records, according to Harder.
Harder said Larry shot himself and his daughter, although autopsies revealed both died as a result of smoke inhalation.
Investigators say the incident happened after the family returned from a trip to the zoo.
Larry Oney's death has been ruled a suicide, and Allison Oney's death has been ruled a homicide.
Larry Oney worked for UHS as a physicians assistant.
Melissa Oney remains at Wilson Hospital, where deputies say she is recovering from surgery.
The family had no reported history of domestic violence.
