Two women were struck by a car in the Sunset District Monday morning and one died from her injuries, according to a spokesperson for the San Francisco Police Department.

The fatal collision occurred at the intersection of 24th Avenue and Santiago Street and marks the city’s 15th pedestrian fatality of the year.

“I’m heartbroken and angry to report a pedestrian fatality in the Sunset. Two seniors were struck and one of them killed by a driver racing east up Santiago who didn’t stop as they crossed the street at 24th Avenue,” Supervisor Gordon Mar said on Twitter.

“I know the pain of losing a loved one to traffic violence. No one should have to experience it. My heart goes out to the victims and their families,” continued Mar, who called for safer streets.

Police arrived on the scene soon after the 10:52 a.m. incident and transported the injured pedestrian and the car’s driver to the hospital. No arrests have been made in the case.

The intersection, a four-way stop is beside Lincoln High School.

While there are plans afoot to make the Sunset more bike- and pedestrian-safe, the San Francisco Municipal Transportation Agency’s plan does not focus on the streets where the incident occurred.
