Rocky star Sylvester Stallone lost his son Sage Friday to an apparent drug overdose.

There were no signs of forced entry in Sage’s home or a suicide note, so authorities are currently pointing their fingers at this tragic event being an accident.

Sage made his big screen debut alongside his father in the 1990 film, Rocky 5. He never broke out like Sly Stallone, but there was clear Hollywood talent in Sage. New York Times critic Janet Maslin wrote in a review at the time of the young boy’s first appearance, “agreeably natural in some scenes, improbable in others.” Sage then went on to work on films the next couple of decades.

Just one day before the news, Sage’s father, Sylvester Stallone, appeared happy as can be down in San Diego for Comic-Con 2012. Stallone was promoting his upcoming Blockbuster, Expendables 2, and he was joined by Arnold Schwarzenegger on a panel filled with laughs and reminiscing. The smiles have since left his face. Sources report that the action hero is a “wreck.”

Rep Michelle Bega released an official statement saying, “Sylvester Stallone is devastated and grief-stricken over the sudden loss of his son Sage Stallone.  His compassion and thoughts are with Sage’s mother, Sasha.  Sage was a very talented and wonderful young man.  His loss will be felt forever.”

Hollywood’s hearts go out to the whole Stallone family. Sage was a mere 36 years old.
