A pregnant woman was shot and killed at a Wawa in Collingdale, Pennsylvania on Saturday, officials say.

Officers with the Collingdale Police Department responded to a shooting at the convenience store around 7:20 p.m., according to an affidavit obtained by USA TODAY.

Upon arrival, a police investigator discovered the pregnant victim, 32-year-old Latoya Davis, "laying on the ground in the side parking lot suffering from a gunshot wound to the upper torso," the document stated. She died at the scene.

Another woman, identified as Evelena Williams, told investigators that she fatally shot the victim, the affidavit alleged. The 30-year-old also informed the official that she had a license to carry a firearm.

The incident was captured on video and showed Williams firing at Davis while she was trying to run away, officials said.
