Days after the San Francisco Police Department published a clearly frustrated tweet regarding yet another pedestrian death on city streets, details on the fatality have been released.

"So another pedestrian struck and killed while in the clearly marked crosswalk. DRIVERS you MUST pay attention to what is in front of you," read a tweet from the "Official Twitter of the San Francisco Police Department Traffic Safety" published Sunday afternoon.

Since it was a holiday weekend, however, details on the collision weren't immediately available — but Tuesday, the SFPD released more information on the death. According to police, a 68-year-old woman identified by the San Francisco Medical Examiner's office as Zhong Nu Liang was walking in the crosswalk of Athens Street and Geneva Avenue at 7:54 a.m. on Friday, February 12.

That's when she was struck by a 22-year-old man driving a white Volkswagen CC, police say.

Though she was rushed to the hospital, she died before she arrived, according to the SFPD.

Despite the strong words directed toward drivers from SFPD's Traffic Safety unit, Bay City News reports that the driver responsible for Liang's death has not been arrested. A call to SFPD to see if he was cited has not been returned at publication time.
