After speaking to witnesses, police say it was 8:08 p.m. Tuesday when 54-year-old Denise Williams fell while walking on the sidewalk along the 3100 block of Frankford Avenue, just outside the Family Dollar store.
While Williams was still on the ground, a black Dodge Charger made a right turn into the driveway to the store, hitting Williams.
The driver got out of the car. She then got back into the vehicle and fled the scene.
The vehicle was last seen travelling west on the 2000 block of Wishart Street.
Williams was transported to Temple University Hospital where she was pronounced dead.
Williams' family is struggling with her death and searching for answers.
"To pull off cold and callous like that, leave a person on the ground, I wouldn't want that to happen to anyone," the victim's brother Naeem Sultan said.
They say the 54-year-old woman was supposed to meet her boyfriend at his Kensington home that night.
"He said he was waiting for her to go to dinner and she just didn't show up for dinner," Sultan said.
Williams was a mother of two adult children and worked as a security guard at the Art Museum.
Authorities released surveillance video of what may be the suspect's car driving along the 3100 block of Frankford Avenue seconds before the accident.
Williams' friends and family want the driver of the Charger to come forward.
"That was a human being. You know what you did. You should come forward and come clean," neighbor Tony Magee said.
"That could be anyone's mother, grandmother, or sister," Sultan said.
A police spokeswoman says detectives are likely awaiting autopsy results, but her family says she had no known medical condition.
Police are asking any other witnesses to contact 215-685-3180 / 3181.
