Paramedics could not revive him and he was pronounced dead shortly after 2:00 p.m., according to the Shelby County Sheriff's Department. Among the highlights of his career, Hayes won an Oscar for his extraordinary theme to 1971's Shaft. And won over a whole new generation of fans with his role as the beloved Chef on South Park.
