Authorities say her mother was sitting on the front steps and witnessed the tragedy unfold.
“I heard someone scream Sandrea, Sandrea, Sandrea three times,” a neighbor told Eyewitness News.
Sandrea Williams was gunned down just after walking away from her steps where she was sitting with her mother.
“Her mom just looked so blank in the face like she was in pure shock,” another neighbor added.
Investigators say just before 11 p.m., two gunmen fired 22 shots, striking two teenage boys and killing Williams on the 300 block of North Simpson Street, but it’s unclear who the intended target was.
Philadelphia Police Lt. John Walker says the gunmen shot Williams in the neck, leg, and back as she was standing in the driveway with her 17-year-old friend, who is in stable condition at Penn Presbyterian Medical Center.READ MORE: Contractor Finds 9 Cats, 7 Kittens Inside Walls Of Abandoned House In Philadelphia
Investigators add that a 16-year-old boy, who was standing on the same street at the time, was also shot and is in stable condition at Lankenau Medical Center.
It’s unclear whether he knew the two other teenagers.
There is no motive at this time.
Right now, investigators are still looking for the two gunmen.
