Autopsy results on Sylvester Stallone's son, Sage, won't be due for several weeks, but investigators may have found some clues to lead them closer to what caused the 36-year-old's death.

TMZ reports that "several little baggies" of white powder were found in the room where Stallone's body was found, and a law enforcement source suggests that it could be cocaine or crushed Vicodin.

TMZ has reported that Stallone lived like a hermit in the weeks before his death, claiming that his room was littered with empty beer cans and more than "60 gigantic empty prescription bottles," including a prescription for hydrocodone, also known as generic Vicodin.

The case is now in the hands of the LAPD's Robbery Homicide department, which is investigating it as a possible drug overdose.
