Marin County investigators are scratching their heads today, after they found themselves unable to link the latest dead body found on their shores with anyone who has been reported missing.

According to Darrell Harris, the Chief Deputy Coroner at the Marin County Sheriff's office, though a number of men have been reported missing in the Bay Area in recent days, none of them are a match for the corpse spotted by a fisherman at 11:35 a.m. last Thursday at Muir Beach.

Harris says that the remains are of an Asian man aged between 25-35 years old. He's about 5'3" and is estimated to have weighed around 160 when he was alive. He has brown eyes, short black hair, a medium-length wiry mustache and a goatee.

The man was dressed in a black, long-sleeved shirt bearing the NordicTrack logo and black Catapult tennis shoes (a brand sold at K-Mart).

He has no tattoos, scars, or marks on his body that might help with identification, nor was any personal property found on his remains. A checkof his fingerprints did not turn up any results, Harris says, nor has he been linked with any other person or a vehicle.

The man, whose body had been in the water from 24-72 hours when it was found, "could have come from anywhere," Harris says.

An autopsy will be performed on the remains this week, Harris says.

If you have any information on the identity of the deceased, Harris asks that you contact his office at 415-473-6043.
