SAN FRANCISCO -- More than 200 people will search Ocean Beach, Golden Gate Park and surrounding neighborhoods on Saturday looking for clues in the disappearance of an Emeryville man who vanished after running the Bay to Breakers race May 19.
Beau Rasmussen, 27, has not been seen or heard from since noon that day, when he said goodbye to his friends in Golden Gate Park at 30th Avenue and John F. Kennedy Drive after the race and headed to Ocean Beach, friends said.
His clothing was later found on the beach, indicating he may have stripped down to his underwear, which was not found, and gone swimming.
He had walked the 7.46 mile course with friends but none accompanied him to the water. No one fitting Rasmussen's description was seen by lifeguards entering the water Sunday afternoon or evening, an official with the U.S. Coast Guard said.
On Sunday night, his phone, credit cards and passport were discovered near the Beach Chalet Brewery and Restaurant across the street from Ocean Beach. His stepmother, Nicole Apelian of Portland, Ore., said he was carrying his passport because he had lost his wallet. She said there are no indications he had a plan to disappear on his own.
He had airplane tickets to fly to Portland, his hometown, on Wednesday to pick up a car and visit his family, including his half brothers Colton, 9 and Quinn, 5.
She said his work clothing for Monday was found set out in his Emeryville apartment.
Rasmussen was reported missing after he did not arrive for his job as a project developer at a San Ramon renewable energy company Monday morning, his family said.
Described as gregarious and athletic by friends and family, Rasmussen is an avid hiker and backpacker who has taken survival training courses.
Still, a lifeguard supervisor called the ocean "angry" that day, adding that seven water rescues and another 1,000 safety contacts were made at Ocean Beach after Sunday's race.
Volunteers are needed starting at 9 a.m. Saturday at Bedford Hall, 2550 41st Ave. in San Francisco. People should wear or bring warm clothing and wear sturdy shoes. Volunteers will search until sunset but people are welcome to come for a few hours at any time during the day, Apelian said.
A group searched about 22 miles of coastline from Ocean Beach in San Francisco to south of Pacific in San Mateo County on Tuesday, but found nothing. A search of hospitals and jails also turned up nothing.
Apelian said they are holding out hope of finding Rasmussen.
"We are doing our best, trying to keep busy and trying to help find Beau. His little brothers just want their big brother back,'' she said.
Rasmussen is white, 6 feet 2 inches tall and weighs 195 pounds. He has brown hair and brown eyes and was last seen wearing jeans and an old maroon football jersey with "Kris" and the number 28 on the back.
The family has asked anyone with video of the beach after the race or any other information to email email@example.com, call 925-961-7397 or contact Emeryville police at 510-596-3700.
