The wife of a retired New York cop who killed his two daughters and then himself on Saturday filed a domestic report the day before the gruesome murder-suicide.

Last Thursday night, 50-year-old Anamarie Hochman and her husband Glen Hochman, 52, got into a heated dispute over a cellphone bill at their home in Harrison in Westchester County, N.Y., officials told the New York Post.

The next day Anamarie Hochman went to her local police station and filed a "domestic incident" report, but she told police she did not want her husband arrested and said Glen has since apologized.

On Saturday while his wife and eldest daughter Samantha were at a casino, Glen Hochman shot and killed his 13-year-old daughter Deanna, his 17-year-old daughter Alissa and all three family dogs, police told the NY Post. Glen fatally shot himself in the garage.

Police arrived at the scene at 4 p.m. after Anamarie called authorities asking for a welfare check because her daughters were not answering their cellphones. Police recovered a weapon and suicide note from Glen at the scene.

"[Anamarie] was asking, 'Why? Why? Why?' " Chief Joseph Bilotto, of Harrison Emergency Medical Services, told the newspaper. He's known the family for years and stayed by the surviving mother and 22-year-old daughter Saturday evening.

"She was just looking for answers as to why he did this, and if he wanted to do this to himself, that's fine, but why take the two kids with him? That was her biggest thing," Bilotto said.

Glen, a cop for 22 years, and his wife were experiencing marital problems of late and were thinking about getting a divorce, sources told the NY Post.

The ex-cop's union lawyer, Warren Roth, told the NY Post Glen took time off last year after an on-duty injury but never showed any "negative emotions."
