Updated at 6:31 p.m.: Aspiring actor and filmmaker Sage Stallone, the son of action movie star Sylvester Stallone, was found dead on Friday at his home in Hollywood, authorities and his attorney said.
"Sylvester Stallone is devastated and grief-stricken over the sudden loss of his son," the actor's publicist, Michelle Bega, said in a statement. "His compassion and thoughts are with Sage's mother, Sasha."
Police and a lawyer for Sage Stallone, 36, gave conflicting accounts of how he was found, but police said there was no sign of forced entry or foul play.
The case was turned over to the Los Angeles County Coroner's Office, Los Angeles police spokesman Lieutenant Andy Neiman said. Coroner's officials also said they were in the initial investigative stages.
Neiman said police found the younger Stallone in the home while responding to a "welfare check."
George Braunstein, an attorney who has represented Sage Stallone for 15 years, said a housekeeper found his body Friday afternoon. Friends and acquaintances had become concerned because they hadn't heard from Stallone in the past day, Braunstein said.
"We don't know any of the details but it must have been some sort of tragic accident. He was full of life and working on projects," Braunstein said. "He wasn't at all depressed or anything like that."
Sage Moonblood Stallone was the oldest of Sylvester Stallone's children and co-starred with his father in two films.
"Sage was a very talented and wonderful young man, his loss will be felt forever," Bega said.
He was the first of two sons Stallone had with first wife, Sasha Czack, whom he divorced in 1985 after about 10 years of marriage.
Sage Stallone made his acting debut in 1990's "Rocky V" and also appeared with his father in 1996's "Daylight."
He also directed the 2006 short "Vic," which screened at the Palm Springs Film Festival.
Braunstein said Stallone was planning on getting married for the first time, and had frequent requests to work on films.
The lawyer also said the 36-year-old greatly admired his father but was working hard to make his own name in the film industry.
"He was very proud of his father and proud to be his father's son," Braustein said.
