On the night of Jan. 6, 2007, two suspects confronted 20-year-old Alberto Casillas and brandished a gun near Club Caliente at 13th and Folsom streets, police said.

Hours later, as Casillas and his friends were driving away from the area at about 2:17 a.m., the suspects fired multiple shots into the driver's side, striking Casillas, police said.

Casillas later died at San Francisco General Hospital.

The suspects are described as two black men, both ages 18 to 25 at the time, one standing 6 feet 4 inches tall and the other was 5 feet 8 inches tall. The suspects' vehicle was reported as a silver sedan with a low spoiler on the back.

The reward, authorized by the mayor's office, was set at $10,000 a few months after the murder and is now set at $250,000.

Police were asking anyone with information about this case to call (415) 575-4444 or text a tip to TIP411.
