Andrew Getty, 47, grandson of the oil tycoon J. Paul Getty, was found at his Hollywood Hills home, his family said Tuesday night. No cause of death was given.
Sources familiar with the investigation told NBC News that there was trauma to Getty's body but that its cause wasn't immediately unidentifiable.

Los Angeles County Coroner's Assistant Chief Ed Winter told reporters "there doesn't appear any criminal activity" and that Getty had been feeling ill in recent days and was supposed to see a doctor Wednesday.
As camera crews from around the world gathered outside the home, police told NBC News that a call came in from an unidentified woman at 2:18 p.m. (5:18 p.m. ET) who reported there was someone dead in the bathroom. Cmdr. Andy Smith, a Los Angeles police spokesman, said a woman who was in the home was being questioned and was being cooperative.
Winter said Getty's body was found lying on his side between a hallway and a bathroom.
Getty was the son of Ann Getty and Gordon Getty, whom Forbes lists as the 869th richest person in the world. The Gettys said they would have no further comment and asked for privacy "during this extremely difficult time."
