San Francisco police were investigating Monday whether an officer wounded in the city's Mission District was shot by a suspect or by his partner, who had fired at the suspect, officials said, reports the San Francisco Chronicle.
A critical piece of evidence, the bullet that pierced Officer Adam Shaw's shoulder Saturday near the intersection of 26th and Florida streets, has not been recovered, police said.
Shaw, 28, and his partner, who has not been identified, were responding to reports of a suspicious vehicle at about 2:45 p.m. when the driver allegedly tried to back into the officers, officials said. The officers were in a marked car.
Shaw, a six-year department veteran, is recovering and "in good spirits," a police spokesman said.
