SAN FRANCISCO (CBS SF) – San Francisco police were asking for the public’s help in finding out what happened to a man who died after being injured during a celebration of the Giants’ World Series win in the city’s Haight-Ashbury neighborhood.

The victim, identified by the medical examiner’s office as 37-year-old San Francisco resident Sean Moffitt, went home after the Oct. 28 celebration and told his roommate he was attacked at about 9:30 p.m. that night in the 1500 block of Haight Street, police spokesman Officer Gordon Shyy said.

Moffitt told the roommate that several people had surrounded him and hit him in the head multiple times with a metal object, police said.

However, Shyy said investigators believe Moffitt may have been injured by accident in the rowdy celebration on Haight Street and are asking for the public’s help in determining what happened that night.

“We’re looking for first-party accounts, anyone who may have been videotaping or taking pictures,” he said.

After Moffitt went to sleep at home on the night of Oct. 28, his roommate noticed that his injuries had gotten worse the next morning and called 911. Moffitt was taken to San Francisco General Hospital, where he died on Oct. 30.

The Police Department’s homicide detail is investigating the case, which is considered a suspicious death pending further investigation, Shyy said.

Anyone with information is asked to call the homicide detail at (415) 553-1145, the department’s anonymous tip line at (415) 575-4444 or send a tip by text message to TIP411 with “SFPD” in the message.
