Robin Williams cremated 1 day after his death, report says

Robin Williams' remains were cremated and his ashes scattered in San Francisco Bay off the coast of Marin County, his death certificate has revealed.

Williams' Marin County death certificate, which was obtained initially by RadarOnline.com, said Monte's Chapel of the Hills funeral home in Anselmo Hills, California, north of San Francisco, handled the arrangements for the Aug. 12 ceremony, a day after Williams' death at age 63.

Williams -- the beloved comedian of such movies as "Mrs. Doubtfire" (1993) and "The Birdcage" (1996), who earned four Academy Award nominations for both comedy and drama, winning for "Good Will Hunting" (1997) -- died Aug. 11 at his home in Tiburon, California, an apparent suicide.

Marin County Sheriff's Lt. Keith Boyd said at a news conference the following day that Williams' assistant had found him "clothed in a seated position, unresponsive, with a belt secured around his neck with the other end of the belt wedged between the closed closet door and the door frame." Williams' death, he said, was consistent with "asphyxia due to hanging."

The death certificate noted the official cause of death was still "pending investigation." The county coroner's office is awaiting results of toxicology tests, which typically take two to six weeks.

On Sunday, Williams' life was celebrated with a service at Glide Memorial Church in San Francisco, the San Francisco Chronicle said. The paper also reported fans have raised a petition to rename the Waldo Tunnel on Highway 101 in nearby Sausalito to honor Williams. The tunnel's arch has a rainbow design, reminiscent of Williams' trademark early-career suspenders.
