Police have identified the woman killed by a hit-and-run driver after she collapsed in the driveway of a Frankford dollar store Christmas night as Denise Williams, 54, of Overbrook.

Williams, of Euclid Street near 54th, fell and was lying on the sidewalk in the driveway of a Family Dollar store on Frankford Avenue near Wishart Street about 8:10 p.m. when a black Dodge Charger turned into the driveway and hit her, witnesses reported. The driver, a Hispanic woman in her 40s, got out, looked at the woman she'd hit and then hopped back in her car and drove away, west on Wishart.

Williams died at Temple University Hospital at 10:57 p.m. of head trauma. Investigators don't know if Williams was conscious when she was hit, nor what caused her to fall. They are seeking the driver and urge tipsters to call (215) 685-3180.
