LOS ANGELES – A search warrant served at Michael Jackson's house the day after he died says family members told investigators they'd found heroin in the singer's room. But tests later showed the substance wasn't heroin, a person with knowledge of the results told The Associated Press.

The person was not authorized to speak with the media and requested anonymity.

The warrant unsealed Thursday showed that various drugs, including marijuana, the generic form of Valium and other sedatives were found in the singer's rented mansion. A detective also indicated that Jackson's body showed signs of injections.

A second warrant served on the car of Dr. Conrad Murray, the focus of a manslaughter investigation, turned up some documents but no additional drugs.
