One child was killed and a woman and child injured Tuesday night in San Francisco's Tenderloin neighborhood when a vehicle struck three pedestrians crossing the street, according to police.
Police were first called to Polk and Ellis streets around 8 p.m. on a report of an injury collision, according to Officer Gordon Shyy.
A vehicle there had struck three pedestrians crossing the street, including one adult female and two young juveniles, Shyy said.
All three were transported to San Francisco General Hospital, but one of the children, a girl, has died from her injuries, Shyy said.
The adult female is in life threatening condition and the boy is expected to survive.
The driver remained on the scene and is cooperating with police.
Drugs and alcohol do not appear to be a factor in the collision at this time, Shyy said.
The child killed in the accident has been identified as 6-year-old Sophia Liu.
