Oh, and there's a description of the murder suspect:

The shooter was described by police as an Asian male in his 20s of thin build, with short dark hair that is spiky in front and wearing an orange San Francisco Giants jacket and blue jeans. He fled south on 19th Avenue, according to police. The suspect's vehicle was described as a mid-90s, dark blue, two-door car that resembled an Acura Integra or a Honda Civic, police said.

This doesn't do much to narrow it down since that could be anyone at a Giants game, but there you have it. Our hearts go out to the victims' families. For reals.
