Multiple guns were seized, and officials said ballistics testing was being conducted to determine if the guns were connected to the shell casings.
Police also pulled a car over on Hagan Street after the incident that was driving with the headlights off. People inside the car had been calling out someone's name as if they were looking for him. Reports stated three of the guns that were seized came from that car.
