Sylvester Stallone's 36-year-old son, Sage Stallone, was found dead in his San Fernando Valley home Friday, according to the Los Angeles Times. Rumors of a drug overdose immediately spread across the Internet, but police are saying those stories may be premature.
Police found Stallone at his home at around 2:15 p.m. and said there were no signs of forced entry or foul play. They did not find any signs of criminal activity.
TMZ reported that Stallone -- whose mother is actress Sasha Czack -- may have died of a prescription drug overdose, but Los Angeles Police Department Commander Andrew Smith told People said that rumor may have been overly hasty.
"It could have been a heart attack or a stroke," Smith said.
Toxicology tests are always taken in these cases as a matter of protocol, but it generally takes a number of weeks before the results are completed, the LAPD commander added. Until that time, the coroner's office will not rule on the cause of death.
"We are in the initial stages of our investigation. We have no information to report at this time," Chief Coroner Craig Harvey told E! News.
Sylvester Stallone's rep, Michelle Bega, issued a statement first reported in TMZ, saying:
“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.”
George Braunstein, who has been Sage Stallone's lawyer for many years, told People the family is devastated by his sudden death.
"(Sage) was full of life, a wonderful, loving person," Braunstein said. "The last time I talked to him a few days ago he was saying he was getting married, he had a lot of things he was working on and seemed very enthusiastic. There was no indication there was any problem."
Stallone was an actor, director, and producer. His film debut was in "Rocky V," where he played his father's son, Robert Balboa. He founded his own production company, Grindhouse Releasing, in 1996.
Sage Stallone had one brother, Seargeoh Stallone. He also had three half-sisters -- Sistine Stallone, Sophia Stallone, and Scarlet Stallone -- from his father’s marriage to Jennifer Flavin.
