A California serial killer is preparing to try to overturn one of his slay convictions by using a defense a la Manhattan “Preppy Killer” Robert Chambers, The Post has learned.

Blackfoot Indian Martin Kipp, 58, who raped and murdered two teens in the 1980s, said that in one of the slayings, his victim, Tiffany Frizzell, wanted to engage in Chambers-like auto-erotic asphyxiation.

“She told me when she had sex with her boyfriend, he would choke her. It really got her off. She liked that ‘Preppy Murder’ stuff,” Kipp told The Post during a two-hour-plus Thanksgiving Day interview at San Quentin State Prison about 20 miles north of San Francisco.

Chambers — a good-looking former altar boy from the Upper East Side — pleaded guilty to the 1986 strangulation murder of 18-year-old Jennifer Levin in Central Park, claiming that he killed her during “rough sex.”

The then-20-year-old Chambers — who was branded the “Preppy Killer” by the media — served a 15-year prison stint and was released, but later returned to the slammer for dealing drugs. His next expected release date is in 2024.

Kipp said he met Frizzell — a community college student from Washington state — on a city bus in Long Beach, California.

He exploited the fact that the 19-year-old was new to the area and intimidated by her surroundings.

“She was looking for help, and I was there,” Kipp said. “She had a boyfriend, but he wasn’t there, and she was feeling lonely.”

They partied and had sex for four straight days at a hotel where she was staying before the start of the semester at school, Kipp said.

On the fourth day, things got out of hand when Frizzell allegedly wrapped a silk scarf around her neck and beckoned Kipp to carefully pull on both ends of the cloth dangling at her side, he said.

“I grab hold of it and pull on it like a tourniquet. I did it the first time, and she got off,” Kipp said, noting that the two had been guzzling beer and whiskey and snorting lines of coke.

“The second time, I did it. She didn’t come back. I guess I didn’t know how tight I was pulling on the tourniquet because of all the substances in me,” Kipp added.

In the late ’80s, he was convicted of Frizzell’s murder and the slaying of Antaya Howard, also 19, after failing to put forth a defense in both cases. He was sentenced to death and incarcerated at San Quentin.

In the Howard murder, Kipp told The Post that she pulled a small Derringer pistol on him during a fight in her car after they had sex.

“I grabbed [the gun] from her. Then she picked up a knife from the floor and I grabbed her throat, and she just went out,” Kipp said. “I didn’t mean to go that far, but I did.”

The double murderer is now making a push to appeal the murder cases based on his new assertions, but he faces an uphill battle.
