Academy-award winning musician, Isaac Hayes, was found dead at his home in Memphis, Tennessee on August 10. The 65-year-old funk-soul legend was found unresponsive on the floor in his home next to a treadmill that was still running by family members around 1:00 p.m., states Shelby country sheriff spokesman Steve Shular. "We don't believe there was any foul play," Shular said. "Based on the statements by family members that Mr. Hayes had been treated of late for a number of medical issues, we believe that led to his death today. There are no plans for an autopsy." Hayes was a talented singer, songwriters and composer. Hayes won an Oscar in 1972 for best original song for the theme from Shaft. He was renowned for his characteristic baritone voice and mastery of several instruments, including the saxophone and the piano. His guest star appearances included TV shows "The Rockford Files" and "Miami Vice." He also appeared in feature films such as "Escape from New York" and "Hustle & Flow." In 1997 he began voicing the role of chef in the animated Comedy Central cable ' series "South Park," but quit in 2006, apparently because of a conflict with Scientology, a religion he followed since the mid 1990s.
