Robin Williams' body was cremated the day after he died, and his ashes were scattered in San Francisco Bay.
The official death certificate does not list an immediate cause of death -- it says "pending investigation."
Williams committed suicide August 11th after hanging himself with a belt at his home in Tiburon, CA.
The coroner is still waiting for the results of toxicology tests to see if Williams had any chemicals in his body when he died. Those results will be available in the next few weeks.
