A deranged New Jersey man said he murdered his girlfriend in self-defense — because she “sicced demons” on him, according to a new report.

Daniel Torres Jr., 38, was nabbed last month for slaying girlfriend Jennifer Beer, after he called 911 and blamed his crime on her demonic powers, a recording of the call obtained Tuesday by The Trentonian revealed.

“I killed my girlfriend, I killed her because she sicced the demons on me,” the man said. “I got proof. I got evidence. I’m very afraid. I got a dog.”

In the nine and a half minute long call, Torres, who said he was armed with two guns and was wearing a helmet and bulletproof vest, ranted about evil forces.

“The demons told me to do it. They attacked me,” the psycho said to the dispatcher. “I defended myself… there’s nobody in here and the demons grabbed me. They throw me all over.”

Torres said he fired at his girlfriend while “trying to shoot the demons,” adding that she had been laughing at him.

He also tried to get the dispatcher to assure him police wouldn’t try to kill him and would accept his evidence of self-defense against “demonic attacks.”

“You need to promise me that I’ll be safe or if not, I’ll just f–king end myself and start a f–king war, because that’s what they want,” he said.

The call ends with a commotion, possibly caused by police arriving, and with Torres saying, “I’m on the phone with 911.”

When police responded to the home they found Torres wearing a helmet and bulletproof vest, and discovered Beer’s body riddled with bullets to the head and chest. The dog was also found, dead, with its neck sliced open.

Torres is being held without bail on charges of murder and animal cruelty. He had a previous conviction of second-degree assault in New York in 2004.

Beer, 31, was a lifelong resident of Hamilton, New Jersey, and was the mother of two daughters, according to her obituary.
