"EMS drivers didn't know where to start," she told The Morning Call. "People were everywhere."
Tashana Santiago, another witness who lives near the nightclub, told The Morning Call she heard a car speeding away after the final shots were fired.
"When everything went silent, all you could hear (was) the screaming and panicking," Santiago told the newspaper. "All I could think was, 'Someone is dying.'"
As of Thursday morning, police had not arrested anyone in connection with the shooting, according to the AP.
Authorities continue to investigate.
