Sunday night's shooting at Turk and Taylor, which sent 7 people to the hospital to be treated for non-life-threatening wounds, all started from a tiff over less than $50.

KTVU has more:

Police Chief Greg Suhr told KTVU the shooter walked up to the intended victim and argued with the man over a debt of less than $50, from a previous drug deal. The man then walked back to his car, and as is seen in the video, opens fire.

KTVU also has surveillance footage of the shooing. What's not seen in the video, however, is the suspect who was reportedly sporting a white t-shirt and dark sweatpants. He jumped into a four door silver sedan with tinted windows shortly after firing into the crowd. Anyway, the video:

So far no arrests have been made.
