The coroner's office used dental records to identify the woman as 42-year-old Nuala O'Donohoe of Dublin. She was last seen sunbathing on a beach at Horseshoe Point and is believed to have been swept to sea by high surf.
O'Donohoe was attending a weeklong yoga retreat at Sea Ranch. Her backpack and a pair of pants were found on the beach.
The Sonoma County Sheriff's Department's helicopter spotted the body Oct. 23 and it was recovered by the U.S. Coast Guard. Autopsy results are pending toxicology tests.
