Adam “DJ AM” Goldstein’s autopsy was completed on Saturday afternoon, but the celebrity disc jockey’s cause of death is still a mystery, according to People.

“The cause of death was inconclusive because we need to do additional testing,” New York City Medical Examiner spokesperson Ellen Borakove told People. “The testing would include toxicology and tissue testing. We don’t expect any results for several weeks.”

Goldstein, 36, was found dead in his Manhattan apartment on Friday after police received a 911 call saying that he had not been seen in two days.
