An unidentified suspect has been taken into custody while hospitalised with injuries.
The shooting took place during a drag show called “Delusions”, hosted by local performer Del Lusional.
The performer took to Twitter early Sunday morning to express shock.
“I never thought this would happen to me and my bar,” Del Lusional wrote in one tweet.
“I don’t know what to do with myself. I can’t stop hearing the shots.”
Another stated: “This doesn’t feel real. Like at all. Walking through the bar that I call my home and seeing it…… like that……
“I went from being so proud of myself for what I accomplished tonight, to…. This. I hate this so much. I hate this so f**king much.”
A third tweet added: “I feel so sick.”
The “Delusions” drag show began at 9pm and was set to finish at 2am, with guests 18 and older.
It is unclear whether the shooting was linked to the event but it has been described as a “hate attack”.
Police have not revealed the name of the suspect and it is unclear whether they are included in the toll of 18 injured.
At an early morning press conference, police shared fears that the death toll could rise from five.
The investigation remains ongoing.
