HAPPY CAMP, Calif. — Police plan to use fingerprints or DNA testing to identify a man found dead last week in the Klamath River along Highway 96 just south of Happy Camp.

An autopsy done Tuesday determined the man drowned in the river at an unknown time, Siskiyou County sheriff's officials said in a news release.

It appeared the man had been in the river for several days before he was found Thursday morning.

The man was wearing several layers of clothing and heavy work boots. A number of items were found in a plastic bag on his person, including a voter-registration certificate from Mexico and a cell phone.

The man's fingerprints will be submitted to the California Department of Justice and the FBI. If identification cannot be made using fingerprint comparison, then DNA testing will be used, sheriff's officials said.
