‘I can’t stop’ shooting

Authorities yesterday revealed chilling new details about how a Queens madman allegedly ambushed his wife as she walked her dog, dragged her by the hair up her front steps, and then shot her in the head before killing her daughter.

“Once I started shooting I can’t stop,” accused gunman Guerino “Mario” Annarumma, 52, allegedly confessed to cops about his maniacal bloodbath Monday — at least some of which was caught by a neighbor’s surveillance camera in Astoria.

The city Housing Authority janitor allegedly said that, armed with a .380 caliber gun, he calmly sat in a Chevy he had rented earlier that morning — and waited.

He was a block from where his estranged wife, Olga, 57, a Russian émigré, lived with her daughter, Valerina Kuzima Lowery, 32, on 38th Street.

Just before 9 a.m., Olga emerged to walk her dog.

“I saw her come out of the house. I got very angry. I walked up to her and said, ‘Why did you call the police?’ She ruined my life,” Annarumma told cops, referring to his twice being arrested for harassing her.

“I threw her to the ground and I kicked her in the face. I told her I wanted to go back to the house. Olga didn’t want to go. She said she didn’t call police. That made me angry more,” said the Italian émigré.

“She didn’t give a s–t what happened to me. I had the gun in my hand and told her we were going back to the house. She didn’t want to go, so I dragged her there. I rang the bell, and the daughter, Valeria, let me in.

“I pushed Valeria on the floor and started shooting. Once I started shooting, I can’t stop. After I shot them, I put the gun in my pocket and walked down the block to my car.”

Annarumma told cops that he tossed the illegal gun in the garbage and went home. He was soon arrested.

In earlier blog rants, Annarumma accused his wife of marrying him for a green card and then refusing to have sex with him.

Olga, who underwent brain surgery, was listed in critical but stable condition at Elmhurst Hospital. Her daughter died from her three bullet wounds.
