PHILADELPHIA (CBS) — A 20-year-old woman is dead after police say she was shot while sitting in her car in the Olney section of Philadelphia, and authorities believe the shooting may have stemmed over a “social media beef.”

The shooting happened around 1:30 a.m. Tuesday in a back alley behind homes on the 5200 block of Westford Road. Surveillance video obtained by CBS3 captures one of the two men wearing hoodies, firing 19 gunshots into a car.

“One young lady who was sitting in the front driver’s seat, Andrea Myers, she’s 20, she was struck in the upper left back,” said Philadelphia Police Capt. Jack Ryan. She, unfortunately, didn’t survive her injuries.”

Minutes after the hail of bullets, the video shows three young men — all in their 20s and two of them related — exit the back of the Nissan Altima.

“I thought it was an automatic weapon and I asked my wife and I said, ‘You hear that?’ And she said, ‘Yeah, it was gunshots,'” said neighbor Donald Montgomery.

Montgomery says crime has picked up since moving into the neighborhood 23 years ago.

“I remember a guy right down here, somebody came up to his house on a bike and he opened the door and they killed him, and that happened about three or four years ago,” explained Montgomery.

Police say Myers, who was from Abington, was in the car with her friends and may not have been the intended target.

“There is maybe some early indications of a social media beef that one of the other individuals may have been having,” said Ryan.

Police are leaning on the public now for help. They’re looking for witnesses that could possibly help lead to an arrest.
