Sage Stallone's parents came together again Saturday morning to say goodbye to their late son, gone too soon at 36 years old.
Dad Sylvester Stallone, mom Sasha Czack led the procession of friends and family who gathered at St. Martin of Tours Catholic Church in the upscale Brentwood area of Los Angeles.
Czack had previously requested that, in lieu of flowers, mourners make a donation to Autism Speaks. Sage's younger brother Seargeoh is autistic. (Stallone also has two daughters with Jennifer Flavin, his third wife.)
Sage was found dead in his L.A. apartment on July 13. No cause of death has been determined yet pending the results of toxicology tests, but police say they do not suspect foul play.
Though friends of Sage have said that he could be withdrawn and prone to anxiety at times, close pal Stephen Wozniak told E! News this week that he refuses to believe Sage, who as a kid starred with his dad in Rocky V, could have taken his own life.
"He was a wonderful guy who loved life and was so sensitive that it got to him," Wozniak said.
