A decaying body was found this week on a beach on San Miguel Island in the Channel Islands, spurring an investigation by federal and local authorities into the mysterious death.
A marine mammal biologist surveying the beach at Simonton Cove late Tuesday afternoon discovered the body in what investigators described as "deteriorated" condition, "indicating that it had been exposed to the elements for some time."
The Santa Barbara County coroner's office will determine the cause of death.
Santa Barbara County authorities are working with Channel Islands National Park rangers and U.S. Naval Criminal Investigative Service special agents.
Authorities recovered the unidentified body from the beach Wednesday.
