Right on the heels of The Expendables 2 panel, one of this year’s highlights from the San Diego Comic-Con, in which Sylvester Stallone and Arnold Schwarzengger traded barbs, fun anecdotes, and an absolute mutual respect for one another, comes the most tragic and distressing news. Sage Stallone, the 36-year-old son of Sly, was found dead on July 13, 2012 in the afternoon in his apartment in Los Angeles, California. Details surrounding his death are still unknown, but police note that Stallone was alone when found and a toxicology report will be pending.

Stallone was born May 5, 1976 to Sly and his then wife Sasha Czack. He was the oldest of Sylvester Stallone’s children and was brother to Seargeoh Stallone and half brother to Sistine, Sophia, and Scarlet Stallone. His stepmother was Stallone’s current wife, Jennifer Flavin. His uncle was sometime actor and musician Frank Stallone and his grandmother was astrologist Jackie Stallone. Reports state that Sylvester Stallone is devastated and grief-stricken, and his compassion and thoughts are with Sasha. The report went on to note that Sage was a very talented and wonderful young man, whose loss will be felt forever.
