Sage Stallone, the 36-year-old son of Sylvester Stallone, was found dead in his Los Angeles home, leaving the actor grief-stricken as authorities investigated the cause, said a publicist and authorities.
Sage Stallone was found unresponsive by an employee and a relative on Friday. There were no signs of foul play or trauma, and no suicide note was found, said Assistant Chief Coroner Ed Winter.
“Sylvester Stallone is devastated and grief-stricken over the sudden loss of his son,” publicist Michelle Bega said in a statement. “His compassion and thoughts are with Sage’s mother, Sasha.”
Sage Moonblood Stallone was the oldest of Mr. Stallone’s children and co-starred with his father in two films. He was the first of two sons Mr. Stallone had with first wife Sasha Czack.
Sage Stallone made his acting debut in 1990’s Rocky V and also appeared with his father in 1996’s Daylight .
Prescription bottles were recovered in the investigation, but Mr. Winter could not say what kind or how many, and whether they had a role in his death.
Mr. Winter said an autopsy will be performed in the next few days and investigators will look into Sage Stallone’s medical history, but a cause of death was likely to take several weeks while toxicology tests are performed.
