The suspect remains unknown and no one is in custody at this time. Apparently, the shooting was an escalation of a “disturbance” that took place inside the club. The disturbance spilled out into the parking lot as the club was shutting down for the night.

“Somebody fired into a crowded parking lot,” Finner said. “We will hold them accountable.”

He also said that the lounge has a history of issues. “They’ve had problems here before and we’re gonna look into that to make sure we’re doing everything we can do,” Finner said.
