An elderly woman is dead and a driver has been arrested after a collision in a crosswalk of one of San Francisco's most notoriously dangerous intersections.

A 78-year-old San Francisco grandmother identified by KTVU as Pei Fong Yim was struck and killed by a 40-year-old San Francisco driver named Calixto Dilinila (photo above), San Francisco Police Department spokesperson Officer Albie Esparza says.

According to Esparza, Yim was crossing Stockton Street in the crosswalk at Sacramento Street, just before the Stockton Tunnel, at 9:49 on Saturday morning, likely headed to her senior center. That's when a yellow Toyota SUV driven by Dilinila struck Yim, killing her at the scene.

This isn't the first fatality at that intersection: according to KTVU, Stockton Street is one of the SF streets "with the highest rates of pedestrian injuries and fatalities," and a witness who spoke with the broadcast station says "I've seen six to eight people get killed on the same spot! I told the city so many times they have to do something about it."

CBS5 reports that Dilinila might have been making a left turn onto Stockton when he struck Yim, and that, according to a witness "the driver did not wait for the lady to fully get across the street."

According to Esparza, Dilinila was booked into San Francisco County Jail for misdemeanor vehicular manslaughter and failing to yield to pedestrian. When contacted by SFist on Monday morning, a spokesperson for the San Francisco Sheriff's Department says that Dilinila has since been released from custody on $10,100 bond.
