LOS ANGELES - Model-turned-bounty hunter Domino Harvey - whose tumultuous life inspired an upcoming film starring Keira Knightley - has been found dead in her bathtub, authorities said yesterday.

An autopsy failed to reveal what killed the 35-year-old troubled beauty, they said.

The daughter of the late British actor Laurence Harvey ("The Manchurian Candidate," "Butterfield 8"), she was on probation for a 2003 methamphetamine conviction and was facing new federal drug charges when she died. But cops said there were no signs of drugs, paraphernalia or criminal activity in her West Hollywood home.

"There was nothing to indicate foul play of any kind. We don't really know anything," L.A. County Sheriff's Lt. Donnie Mauldin said.

Toxicology tests are under way to determine if any drug or substance played a role in her death, said Lt. Cheryl MacWillie, a spokeswoman for the L.A. county coroner. "There were no injuries to the body. She did not drown. She was never under water," she said.

The ex-fashion model, who traded runway glam for a dangerous job hunting bail jumpers, died Monday night.

After an early career as a Ford model, Harvey, whose mother was Vogue model Pauline Stone, decided to strike out on her own, working as a nightclub manager, a ranch hand and for the San Diego Fire Department before joining a bail bonds agency in 1994.

Named after a James Bond movie heroine, Harvey often hunted fugitive drug dealers and would reap 10% of the bail amount on those she captured.
