A missing kayaker in California has been found dead days after he disappeared during a crabbing trip with friends, authorities said Thursday.

Clinton Yoshio Koga, 39, was recovered Wednesday by California Recovery Divers, a volunteer aquatic search group, about 100 yards from the shore of Lawson’s Landing, where he had gone fishing with friends on Tomales Bay, the Marin County Sheriff’s Office said.

Koga had gone out alone onto the bay at around 6:10 p.m. on Jan. 27 to retrieve a crabbing cage. Less than 20 minutes later, a friend noticed that he could not see Koga’s kayak from the shore, the sheriff's office said. 

The friend reported Koga’s disappearance to the sheriff’s office while his other friends searched the bay waters for any signs of their missing friend.

The Marin County Fire Department, the Marin County dive team, the Sonoma County Sheriff’s Office helicopter, and the U.S. Coast Guard assisted in the search for Koga, which officials described as "intensive."

However, Koga was not found despite extensive effort and the search was suspended.

Koga, who was from Brentwood, California, was remembered by friends on social media.

"I couldn't catch a football worth a damn growing up but you always kept throwing it my way," friend Rudy Carranza said, according to FOX2 KTVU. "I will always miss you and I will try to pick up the pieces and just keep going."
