HAPPY CAMP, Calif. — Siskiyou County officials are working to confirm the identity and determine what happened to a man found floating dead in the Klamath River.

A Happy Camp resident called the Siskiyou County Sheriff's Department at about 10:20 a.m. Thursday to report finding a dead man in the Klamath River in the Ferry Point area southwest of Happy Camp, just past mile 30 of Highway 96.

Deputies recovered the body, which appeared to have been in the water for several days, sheriff's department spokeswoman Susan Gravenkamp said.

The man was wearing several layers of clothing and heavy work boots, she said.

He had a cell phone and personal items, including a voter- registration certificate from Mexico, in a plastic bag in his pocket.

An initial examination found no obvious cause of death, but an autopsy is set for Monday, Gravenkamp said.

The sheriff's department launched a boat Thursday afternoon to search along the river for a campsite or vehicle that the man might have been linked to. A Coast Guard helicopter searched from the air, but neither search crew found any evidence of where the man might have come from or how he had ended up in the water.
