Johny Castillo-Alonzo, 26, of Daly City was killed while driving at Cesar Chavez and Folsom Streets after another driver ran a red light and broadsided his car at about 2:20 a.m. on Saturday, according to reports. Police are still looking for the man, who fled on foot. He had hit Castillo-Alonzo’s car at such high speed that it crashed into a third car and a residential building, KTVU reported.

According to the San Jose Mercury News, several passengers in the suspect’s car reportedly also fled:

As of Monday afternoon, the occupants of the suspect car still had not been found, Esparza said. In light of Alonzo-Castillo’s death, the driver is wanted on vehicular manslaughter charges, and the driver and passengers are wanted on charges of felony hit-and-run resulting in death.

Car occupants tend to be killed in San Francisco traffic less frequently than pedestrians and bicyclists, who are the far more vulnerable users on the street. But even those traveling inside steel frames on these streets can have their lives ruined or taken by reckless driving. Of the 28 traffic deaths in 2011, eight were in motor vehicles, according to SFPD stats; more recent totals weren’t available. Roughly 60 percent of trips are taken by auto in the city, according to the SFMTA.
