Family and friends mourned the son of movie star Sylvester Stallone at a private funeral on Saturday, about one week after he was found dead.

Celebrity websites tmz.com, people.com and others published pictures of the Rocky and Rambo star outside the funeral for his 36-year-old son, Sage, who was found dead on July 13.

The official cause of death is still undetermined pending toxicology results.

The actor did not issue a statement on Saturday, but has asked the media and public "to have my son's memory and soul left in peace."

 Sage was the younger of two sons Sylvester Stallone had with his first wife, Sasha Czack. The couple divorced in 1985. Stallone fathered three other children with his third wife, Jennifer Flavin.
