A mother and her 5-year-old daughter were struck by an elderly driver in the Stonestown Galleria parking lot Wednesday, leaving the child with critical injuries, a San Francisco Police Department spokesperson says.

According to the SFPD, the 45-year-old woman and her daughter were in a crosswalk in front the Stonestown City Sports Club at 12:23 Wednesday afternoon when a Toyota RAV-4 SUV driven by an 86-year-old woman failed to stop at the intersection and struck them both. The mother was left with serious injuries, and the child with life-threatening injuries as a result of the collision.

The Ex reports that the driver stopped at the crash and cooperated with investigators, and that "it's unknown why the driver didn't stop for the pedestrians." Neither drugs nor alcohol appear to be a factor, an SFPD spokesperson said.

KTVU reports that the driver was eventually taken from the scene "to the hospital for an undisclosed ailment." The Golden Gate Xpress says, however, that the driver "experienced chest pains after the accident, but declined medical treatment." A call to SFPD to figure out which of these reports is accurate was not returned at publication time.

According to the Chron, a police spokesperson said "that it was too early to determine fault and that no citations had been written."

According to Cornelius Jones, a witness who spoke with the Golden Gate Xpress, the driver didn't get out of her car after the collision, but just sat inside it, apparently waiting for police to arrive.

“She just pulled to the side and sat there...The police went over there and started talking to her.”
