A 28-year-old San Francisco man died after he fell off a fourth-story roof during a Bay to Breakers party Sunday, authorities said Monday.

Another man, a 27-year-old Oakland resident, was reported missing Monday after having finished the race at Ocean Beach.

The fall victim was David Hamzeh, who worked at the San Francisco online marketing company DemandForce, said spokeswoman Diane Carlini of Intuit, which owns the firm.

Hamzeh had been drinking at a party at 2040 Fell St. across from the Panhandle before he fell off the apartment building's roof around 3:30 p.m., police said. He died at San Francisco General Hospital shortly afterward.

Police said the fall was an accident.

Henry Hutchinson, who lives next door to the apartment building, said a few dozen people were at the party and that it wasn't a rowdy gathering.

"It was really mellow," he said. "I just think it was just the one wrong move."

Hutchinson said he had been sitting in his living room watching the race event's revelry in the Panhandle when he noticed crowds react to Hamzeh's fall.

"I saw the thousands of people turn and stare and look and watch at what happened," Hutchinson said. "Then I came down and saw the man on the sidewalk."

It appeared he fell on his head, Hutchinson said.

Uartine Gentry, 70, was watching the crowd from his second-story apartment across the building's courtyard when he heard the fall.

"I heard the thwack and then everyone started screaming," Gentry said. "When I ran down there, he was laying there completely white, so we thought he was gone."

Gentry said partygoers were lounging on the sidewalk having a beer or two when Hamzeh fell in front of them.

"They were very upset," he said. "The guys were crying, the girls were crying."

Authorities are also investigating reports of a 27-year-old man who has not been seen since he finished the race and left his friends to go to the beach about noon.

Beau Rasmussen's belongings were later found near Beach Chalet Brewery and Restaurant. His friends and co-workers alerted authorities when he didn't show up for work Monday.

The beach's lifeguards did not report anybody matching Rasmussen's descriptions going into the water the day of the race, according to the Coast Guard.

Rasmussen is about 6-foot-2 and 190 pounds, with brown hair and brown eyes. He was last seen wearing an old maroon football jersey with the number 28 on the back.
