At around 1 a.m this morning, a man was shot and killed just outside North Beach bar Fuse. According to reports, the unidentified man had a few drinks, walked outside and returned later, "only to be shot twice in the back as he tried to re-enter the club." Once he stumbled back into the club, all chaos broke loose. A bartender tried to perform CPR, but the man was "pronounced dead about an hour later at San Francisco General Hospital." Word has it the man also might have known his assailant. No arrests have been made. Update: The victim has been identified by medical examiners as Richard Barrett, 29. who was "trying to run from the men when he was shot." Brazen.
