An argument on the Mission District corner of 17th and Capp Streets took a potentially deadly turn Wednesday night, when a suspect shot two men, critically wounding them.

According to San Francisco Police Department spokesperson Officer Grace Gatpandan, officers were called to 17th and Capp on reports of a shooting.

Witnesses say that two men were "engaged in a verbal altercation" with a third man, who eventually "pulled out a handgun" and shot them both.

SFPD Captain Mark Osuna told Capp Street Crap that "The suspect (was) in the intersection. Two people are on the sidewalk. The suspect pulls out a gun, fires about three, four rounds. We think, four rounds."

The shooter then fled south down Capp Street and remains at large, Gatpandan says. Both victims were transported to San Francisco General Hospital with life threatening injuries.

As always, Gatpandan says that anyone with information regarding the shooting encouraged to call SFPD's Anonymous Tip Line at 415-575-4444 or to send a text to TIP411 with SFPD at the beginning of the message.
