DJ AM

Though the details surrounding DJ AM's death remain medically inconclusive, more information from the celebrity deejay's death is coming to light.

DJ AM, whose real name is Adam Goldstein, sent his last text message to two friends at 1 a.m. Friday morning, a police source told People. The message regarded a Friday-night gig that Goldstein was scheduled to play at the Palms Hotel in Las Vegas.

A friend of Goldstein's called 911 about 16 hours later, after Goldstein failed to answer phone calls from his traveling companions, according to the source.

New York police broke down the door to Goldstein's SoHo apartment, and found him lifeless in bed, wearing sweatpants, the source said. A crack pipe was nearby, and police also found half a bag of crack cocaine and prescription drugs, according to the source.

An autopsy was performed, but an official cause of death is inconclusive, pending additional toxicology and tissue tests, which could take several weeks, the New York medical examiner's office told TVGuide.com.

Goldstein — who had often talked about his past of drug addiction and was set to host a new MTV reality show aimed at encouraging young drug addicts to clean up their lives — claimed to have been sober for more than 11 years.

He also recently told The Associated Press that while filming the show he held a crack pipe for the first time in years. However, he used the experience as a reminder of what he'd overcome. "There's no better way to remember what it was like when I was at my bottom than to see someone at their bottom," Goldstein said.

No decision has been made about the future of Goldstein's show, titled Gone Too Far, an MTV rep tells TVGuide.com.
