his father in Rocky V, was found dead in his Los Angeles home Friday.
Los Angeles police say they were sent to investigate a death at a home on Friday afternoon, but could not confirm the person’s identity or offer details. Coroner’s officials also say they were in the initial stages of the investigation.
A source said pills were found at his home, but it was unclear if his death was a suicide or accidental.
The LAPD said the case has been referred to the coroner.
Los Angeles police officers found the body at 2:17 p.m. while conducting a welfare check at the home after somebody reported that Sage couldn’t be reached. There were no signs of foul play or forced entry.
“It sounds like a terrible tragedy. He was way too young to die,” LAPD Commander Andrew Smith told reporters. 
He adds that reports that Sage died from a prescription overdose are premature.
“It could have been a heart attack or a stroke,” he says, adding the coroner’s office will likely spend several weeks on a toxicology report before it can reach any such conclusion.
“There is no suspicion of foul play or criminal activity”, a rep said, adding that police went to the home for a “welfare check,” when someone couldn’t get in touch with Stallone and asked the police to investigate.
Sage’s attorney said there were no indications of problems.
“He was in good spirits, and working on all kinds of projects,” says Braunstein. “He was planning on getting married … He was an extremely wonderful, loving guy. This is a tragedy.”
TMZ UPDATE: 5:15 PM PT: Sylvester Stallone’s rep, Michelle Bega, tells TMZ, “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.”
