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 on 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.
