A wedding party attendee spent more than 14 hours missing Sunday after taking a late-night walk on a remote Rockpile Road property, Sonoma County sheriff's officials said.

Authorities launched a full-scale search for Moosa Sulman, 28, of San Francisco, after noon Sunday when fellow wedding revelers filed a missing person report, Lt. Steve Brown said.

Sulman and others had taken a walk at about 3 a.m. Sunday on one of the remote property's many trails, Brown said.

At some point Sulman, who had several alcoholic drinks during the celebration, said he didn't feel well and stopped to rest, Brown said. He was wearing dress shoes, slacks and a T-shirt.

The others returned to the house.

Attendees started looking for Sulman at about 9 a.m. but didn't find him, Brown said. They called authorities at about noon.

The Sheriff's Office search and rescue team fanned out on foot to search the remote property on the 15000 block of Rockpile Road, Brown said.

Tactical flight officer Chris Mahoney said he and the helicopter crew flew over the area for two hours before returning to the hangar to refuel.

The off-road motorcycle deputies left their posts at the Sonoma Raceway off Lakeville Highway to join the search, Mahoney said. The sheriff's marine unit patrolled the lake shore.

Sulman apparently went to sleep somewhere on the rugged property and was awoken by the sound of the sheriff's helicopter sometime after 1 p.m., officials said.

Sulman was walking on a trail about one mile from the residence at about 5:30 p.m. when deputies on off-road vehicles found him, Brown said.

The helicopter team landed and flew Sulman back to the residence.

"He was fine," Mahoney said.
