Four people were injured, one fatally, after a spate of car collisions with pedestrians in San Francisco.

On Sunday night at 6:30 p.m. at Mason and Turk Streets, a 50-year-old woman and an 80-year-old man were both struck by the driver of a light-colored BMW, according to the San Francisco Police Department.

The driver fled up Mason Street, and is still at large. The man and woman were transported to San Francisco General Hospital, and are expected to survive.

Less than 12 hours later, an elderly male pedestrian was struck by a woman driving on Geary Boulevard at 10th Avenue at 6 a.m. Monday. The driver stopped and was cooperating with the investigation, and the victim was taken to SF General with critical injuries.

Within the same hour, but the other side of Golden Gate Park, a pedestrian was struck and killed by a driver at 43rd Avenue and Sloat Boulevard, near the SF Zoo.

According to SFPD, they received a call regarding the collision at 6:57 this morning, and, upon arrival, "located a male who had been struck by a vehicle," SFPD spokesperson Sergeant Monica MacDonald said.

Though officers performed CPR on the man, he did not survive his injuries, MacDonald said. According to the Ex, the driver remained at the scene and cooperated with investigators.
