“He was very creative, energetic and very full of life,” Braunstein told E! News. “There was nothing dark or depressing, no problems, certainly no financial problems.”

“The final cause of death has been deferred for additional testing,” the coroner’s office said in a statement. “No results will be released until testing is complete—six to eight weeks minimum. LAPD has requested a security hold on further details related to the death.”

A Father’s Grief

As rumors circulated around Sage’s death, Stallone requested respect and privacy for the family, adding that there is no greater pain for a parent than the loss of their child.

He asked the public to remember Sage with fondness and to stand in empathy with him and his ex-wife, Czack.

“I am imploring people to respect my wonderfully talented son’s memory and feel compassion for his loving mother Sasha, because this agonizing loss will be felt for the rest of our lives,” he said.

Stallone added that as his first born, Sage held a very precious place in his heart.
