O'Bryan Spikes was killed in the shooting that left at least two people in critical condition and others in stable condition. The others who were injured have since been treated and released from a local hospital, according to local news outlet Fox 19.

More than one gunman was involved and they all remained at large as of Monday afternoon, although the number of shooters was not immediately announced.

"A lot of chaos, obviously, when shots were fired," Cincinnati Police Captain Kimberly Williams said. "People were just trying to get out and get out of harm's way."

Cincinnati Police Chief Eliot Isaac said it was only a matter of time before the culprits were brought to justice, Cincinnati.com reported. "We are confident we will find who is responsible for this," he said.

"We will do everything in our power to cooperate and make sure the monsters that did this are caught and brought to justice," Cameo nightclub owner Julian Rodgers said in a brief statement Sunday.

One eye witness in the nightclub described her personal horror when she detailed her experience inside the Cameo nightclub to local news outlet WCPO.

"All I could think about was, 'Is a bullet going to fly past me? Am I going to get hit and drop?’" the woman who was identified only as Sherell said. "I thought I was going to die. At that point, survival skill started kicking in. "Once I heard the third shot -- I didn't know whether it was coming from outside, someone was shooting at the club, or whether it was coming from inside. I immediately dived to the ground to the side, and my boyfriend dived on top of me."
