His friends said he gave them a “thumbs up” and then vanished, as 14-foot waves that were 9 seconds apart crashed around him and swept him out, then underwater.

According to Monterey County Sheriff’s Office, Stuntz’s friends immediately went for help.

Members with MCSO Search and Rescue, Mid-Coast Fire, Cal-Fire, California State Park Rangers/Lifeguards, and CHP Helicopter helped in the search effort.

The U.S. Coast Guard boat and helicopter conducted searches into the night.
