The cause of ADAM 'DJ AM' GOLDSTEIN's death remains a mystery as authorities call for further tests on the star's body.
Officials completed an initial autopsy on Saturday (29Aug09), one day after the 36 year old was found dead in his New York City apartment from a suspected drug overdose.
But the initial investigation was inconclusive, and more toxicology tests, which are expected to take weeks, are needed to determine what killed Goldstein.
New York City Medical Examiner spokesperson Ellen Borakove says, "The cause of death was inconclusive because we need to do additional testing. The testing would include toxicology and tissue testing. We don't expect any results for several weeks.
"It's under investigation and when the investigation is complete we will have a cause of death and a manner of death."
Officials at the Medical Examiner are cooperating with the New York City Police Department in an official investigation, amid reports Goldstein was found with drug paraphernalia in his home.
