Police were called around 3:35 a.m. about an altercation inside the Boom Boom Sports Bar on South New Braunfels Avenue, which was operating after-hours, McManus said. It’s believed that the owner was trying to close the establishment when the altercation began, the chief added.

The chaos spilled over into the parking lot, where a man went to his car, grabbed a long gun and started shooting. Five people were struck, McManus said.

Two of the victims are women, the other three are men, all in their 20s and 30s, McManus added.
