The autopsy on Sylvester Stallone's 36-year-old son, who was found dead in his Los Angeles home of a suspected prescription pill overdose on Friday, was completed Sunday, but the Coroner's spokesman said it can take six weeks for toxicology tests to be completed.

Stallone was reportedly dead for several days before he was discovered by a housekeeper just before 3pm at his home in Studio City, and prescription pill bottles were found littered at the scene. It's also been reported that the actor was still alive through Sunday, and posted 17 pictures to his Facebook profile (like the one above) just hours before his body was discovered.

The Rocky star, who was at Comic-Con promoting The Expendables 2 when he received the news, released the statement through his rep: "Sylvester Stallone is devastated and grief-stricken over the sudden loss of his son Sage Stallone. His compassion and thoughts are with Sage's mother, Sasha. Sage was a very talented and wonderful young man. His loss will be felt forever."

Sage was planning to marry his longtime girlfriend in Las Vegas next weekend.
