HOT SPRINGS, Ark. -- An Arkansas man is accused of using his prosthetic arm and a rock to beat another man to death.

Hot Springs police say 52-year-old Ray Allen Brown is charged with second-degree murder in the Tuesday night killing of 52-year-old Robert Brindley.

The affidavit says Brown told police he hit the man with his prosthetic arm, which sent him to the ground. Brown said he then picked up a rock and smashed Brindley's head.

He remained in jail Friday on $10,000 bond and has a court appearance set for June 12.
