The woman who reported the body has not been identified and is not under arrest. She is helping officers with their inquiries.

Los Angeles County coroner's assistant chief Ed Winter said that medication had been found at the scene, reports the BBC.

"The tentative information that we do have is that he was not feeling good for the last couple of months and he supposedly had an appointment tomorrow with a personal physician," Mr Winter said.

"He had some medication that we recovered and don't know if he had taken the medication or what his medical history is. We do have a doctor's name that we're also going to follow up."

He added that toxicology tests could take a number of weeks.
