Son of Actor Sylvester Stallone was found dead at his Studio City home on Friday.

His lawyer, George Braunstein, said that the body of the younger Stallone was found by his housekeeper.

According to the LA Times, at a news conference on Friday night, Ed Winter of the coroner's office said the autopsy would occur in the next few days and that a security hold has been placed on the case.

The cause of death of the 36-year-old actor and producer is still under investigation.

"We don't have any of the details," Braunstein said. "He wasn't depressed. He was thinking about getting married. He had his whole life ahead of him."

Stallone's father was said to be "devastated and grief-stricken" by his son's death.

The young Stallone was born on May 5, 1976, in Los Angeles and was the first son of Stallone and Actress Sasha Czack. His acting career began in "Rocky V," which is the 1990 installment of the "Rocky" movie franchise. At the age of 14, he played Rocky Balboa Jr., the son of his father's character, Rocky Balboa.

"Sage was a very talented and wonderful young man," said Sylvester Stallone's publicist, Michelle Bega. "His loss will be felt forever."
