Minutes before two merchants were found shot to death in Fisherman's Wharf, police officers were across town responding to another homicide in Potrero Hill.
At about 8:15 p.m. Sunday, a man was shot and killed on the 900 block of Connecticut Street, outside an apartment building. Police said the victim apparently got into a fight with two suspects.
The victim, who has not yet been identified, was taken to San Francisco General Hospital, where he died.
Police have arrested Antoine Gray, 29, and Toyia Taylor, 18, in connection with the shooting.
About five minutes later two merchants were shot and killed at a luggage and souvenir shop along Jefferson Street. Police arrested Hong Ri Wu, 54, on suspicion of shooting the two victims -- Qiong Han Chu, 30 and Feng Ping Ou, 3o.
The three shootings brings San Francisco's homicide rate to 11 this year.
