During the press conference, police played a video of the scene showing the outside of the store. In the video, a man in shorts without a shirt opened the store door and started firing.
“The weapon used in this incident was a .40 caliber pistol. It had an extended magazine,” Bryan said. “We know he fired at least 20 cartridges because we found the caps.”
Bryan added that police are working to determine a motive. “Why is that one of our big questions right now,” he said.
Police are also looking for a person interested in the case and a white van.
“There’s a second person we’re looking for,” Bryan said. “Right now, we don’t know who he is … He doesn’t suspect the shooting, but he’s an interesting person we want to talk to.”
Garland is part of the “Metroplex” of North Texas, northeast of Dallas.
