New York, July 18 (ANI): Sage Stallone's Los Angeles apartment was strewn with more than 50 bottles of powerful prescription painkillers- but most of the bottles were mysteriously empty, sources close to the investigation have revealed.

Sources said investigators also found numerous bags of white powder in the apartment.

Police found Stallone, son of Rocky star Sylvester, dead at age 36 in his Studio City, Calif., apartment Friday, and toxicology tests from an autopsy are pending.

The bottles at the scene were for hydrocodone, the generic form of Vicodin, each with the capacity to hold 500 pills.

These were the kind of bottles a pharmacy gets, the New York Post quoted a source close to the case as saying.

The strange thing is that, for the most part, the bottles were empty, the source continued.

The source said the labels were removed on about 40 of the bottles, but, There was residue from the labels which was also being tested.

But Stallone's camp declined to comment on the pills. (ANI)
