A woman died during a night of "bizarre sex" in which her husband used an electrical cord to stimulate her, but ended up giving her a fatal shock, police said.

Kirsten Taylor, 29, was found unconscious Wednesday night at the couple's Pennsylvania home. She was taken to York Hospital, where she was pronounced dead.

Toby Taylor first said his wife was shocked by a hair dryer, according to a police affidavit. But when burns were found on her body, Taylor told police that he had clipped an electrical cord to his wife and plugged it into a power strip, which he then turned on and off.

He told authorities the couple had used the technique before.

Taylor, 37, was jailed Thursday in lieu of $100,000 bail on involuntary manslaughter and reckless endangerment charges. He did not have a lawyer at his arraignment and no lawyer had been entered in his court file as of Friday.

York County Coroner Barry Bloss called it a case of "bizarre sex."

"I have never seen anything like this," Bloss said. "Even if you did it before, you have to know you could kill someone."

The township police chief, David Sterner, said the jolt of electricity is believed to have triggered a heart attack in the woman.

An initial autopsy did not determine the cause of death, Bloss said. A final determination awaits further testing of the electrical equipment and a toxicology test, he said.
