Police in Queens are investigating an apparent murder-suicide after a couple was found dead inside a Jamaica home Saturday.

Authorities say they received a 911 call around 1 p.m about a stabbing and found the bodies of Paul Johnson, 47, and Regina Alston, 46, in a house at 109-65 Liverpool Street.

Alston had multiple stab wounds, while sources say Johnson hanged himself with a dog leash in a stairwell and had cuts on his body.

Family members say Johnson waited for Alston and one of their two daughters to return home before the attack, though the girl escaped unharmed.

"He began to say 'I'm sorry, Mike, I'm sorry, I killed her.' And when we finally get in the house we saw him hanging. And she was dead in the room," said the victim's nephew, Michael Ware.

"I can't even imagine what would even make him do something like this. Even an act of desperation. All he had to do was reach out. We would have helped him," said the victim's brother, Ronald Alston.

Family members say Johnson was unemployed and depressed and that Alston had tried to end their relationship.

They say she asked him to move out of their apartment and had gotten a restraining order against him, but it's unclear if that order was still in effect.

Alston's landlady, Helen Law, told NY1 that Johnson moved out of the house around two months ago and that he had been previously arrested for a domestic dispute.

The investigation is ongoing.
