Nicolette Law, 20, of Allentown, was shot dead by Edward Joel Rosario-Jimenez on Friday evening in the parking lot of the Whitehall Township Walmart, police said.
More than $4,700 had been raised in funeral funds for Law's family on a GoFundMe page as of Monday morning.
Officers arrived to the MacArthur Boulevard store around 7 p.m. Friday on reports of shots fired, where they found Law and another gunshot victim near a parked car -- the engine still running, Whitehall police said.
Surveillance footage shows a vehicle pulling up and parking in the merchandise section of the lot, before a Toyota SUV pulls up and parks directly in front of it.
A witness told police she arrived in the Toyota with Rosario-Jimenez and two others, when Rosario-Jimenez began arguing with one of the soon-to-be victims, authorities said.
The witness said she left in the Toyota after hearing gunshots, but Rosario-Jimenez remained in the parking lot. Another witness told police they saw Rosario-Jimenez fire several gunshots at the victims.
Police found a handgun hidden in a snowbank adjacent to where the shooting occurred, authorities said.
Rosario-Jimenez was later charged with criminal homicide, attempted criminal homicide, aggravated assault and firearm not to be carried without a license.
Details surrounding the incident were not immediately clear.
