LEBANON, Maine — A neighbor has shared what she saw, and heard, minutes before a suspected murder-suicide in Lebanon over the weekend.

State Police say there was no history of domestic violence between a man and his former girlfriend killed in an apparent murder-suicide in an upstairs apartment in Lebanon, but neighbors say the couple did argue.

Shelly Stevens is the alleged victim’s neighbor.

She told CBS 13 after police evacuated them, a friend of Allyson Parker played a recording she’d made, of Parker and her estranged boyfriend arguing seconds before the shooting.

“So we heard Allyson say to him ‘I’m leaving.’ And he said ‘No, you’re not,’” Stevens said. “She goes ‘Yeah, I am.’ And he goes ‘No, you cheated on me.’ And she goes ‘No, I didn’t.’ And then we heard four shots.”

Police say Parker recently ended a three-year relationship with Thomas Doyon.

They say she, her parents and a friend went to the house to move her things out.

Police believe Doyon shot Parker, then turned the gun on himself.

“He seemed like a nice guy,” Stevens said. “Who knows? If he’d been a good guy and actually had been nice to her, she might have taken him back.”

The head of Caring Unlimited in York County said domestic murders are extreme examples of an abuser exerting power and control.

“Other things don’t matter. It’s about what that person wants and how they’re going to get it,” Caring Unlimited Executive Director Susan Giambalvo said. “It’s extremely self-centered. It’s the idea that I am entitled to have somebody else who is going to do what I say and act in the way I want them to.”

Allyson Parker leaves behind her 7-year-old daughter.

“Really feel sorry for that family,” Stevens said. “I mean, that little girl, it was Mother’s Day weekend. It’s sad. And it’s such a waste of life.”

State police say Doyon owned the handgun used in the shooting, but police have no information on where or when he got that gun.
