Sylvester Stallone's son is thought to have been dead for some time before his body was discovered. Sage Stallone, 36, was found unresponsive at his home in Studio City, Los Angeles yesterday (13.07.12) and although paramedics arrived at the scene at 3.05pm, they left again within half an hour and the body was taken to the coroner's office rather than the hospital. A source told RadarOnline: "I suspect he had been dead for quite a while when he was discovered. Usually medics will be at the scene for around forty-five minutes but they were out of there within half an hour." Prescription drugs were reportedly founds beside the body although if the death was caused by drugs, friends believe it was an accidental overdose. The source added: "There were a number of prescription bottles found at the scene but it did not appear to be suicide and no note was found." Meanwhile a friend revealed the actor, director and producers was in good spirits just two weeks ago. The pal said; "I saw him two weeks ago and he seemed great. He was healthy and upbeat and didn't seem depressed at all." Sage was Sylvester's son from his first marriage to Sasha Czack.
