The video shows a light-colored 2004-2008 Nissan Maxima that police believe was being driven by the suspect.
The violent attack happened on New Year's Eve day.
Officers responded at 9:50 a.m. to the 7100 block of Montague Street for a report of shots fired during a robbery.
They arrived to find a blood on the street and a trail of blood leading an alley between Erdrick and Montague streets. A short time later they found a 75-year-old woman who had been shot in the face.
The victim said she had been walking home from a supermarket when a silver or white Nissan Maxima pulled up beside her.
The driver reached out and tried to grab her purse, threatening to shoot her.
When the woman refused to give him the purse, the suspect shot her once in the face and drove away, dragging her for several feet.
He got away with the woman's purse, which contained $400 and her cell phone.
Police are looking for an Hispanic man in his late 20s with a trimmed beard. He was wearing a red knit cap and was armed with a handgun.
The car seen in the surveillance video is described as 2004-2008 Nissan Maxima white or silver in color with a sky or moon roof and damage along the passenger side.
Anyone with information is asked to contact Detective Sullivan of the Philadelphia Police Northeast Detective Division at 215-686-3153/3154.
