Police are asking the public for pictures and video that might have captured a fatal assault in Golden Gate Park the day of the Zazzle Bay to Breakers.
Stephen Martin, 30, of Santa Clara was beaten into a coma, and on Friday he was taken off life support.
“This is a tragic crime,” police Chief Greg Suhr said. “This gentleman finished running the Bay to Breakers race several hours before, they’re socializing with this group and now he’s dead.”
Anyone who was in the Sharon Meadow area of Golden Gate Park on May 20 might have information that will help police.
“We can’t get enough photographs,” Suhr said.
Martin and friends had run the race earlier that day, police Cmdr. John Loftus said. They were wearing Troll costumes; dressing up is a popular tradition of the race.
The group later gathered in the meadow near the tennis courts and Sharon Art Studio, police said. About 5 p.m., there was a confrontation between Martin’s group and a group of about 12 people. Martin was then punched by someone in the other group. He fell to the ground and struck his head on the pavement.
Police do not have many details about the other group of people. The men were wearing red-and-white 49ers jerseys, Loftus said. Several of the women were wearing purple and at least one had on an orange tutu.
The argument was reportedly over a cellphone, Loftus said.
Anyone with information on the attack can call the Police Department at (415) 553-1145 or anonymously at (415) 575-4444. Info also can be texted to TIP411, with “SFPD” in the subject line.
As of Monday, no arrests had been made.
