Local and federal agents are searching for people with information about a deadly mass shooting that left four people dead and at least 17 others injured outside a Birmingham club Saturday night.

The shooting happened just after 11 p.m. in the 2000 block of Magnolia Avenue South, as people were standing in line to get into Hush, a hookah and cigar lounge.

Birmingham Police Chief Scott Thurmond said the shooting may have been a murder-for-hire and that more than 100 shell casings were collected at the scene.

Who was killed?

Sunday evening, police identified three of the four people killed as Antria Holloman, 21, Tahj Booker, 27, and Carlos McCain, 27. A fourth person died at the hospital.

Who was injured?

Police estimate that 17 people were hurt in the shooting and ensuing chaos.

Gabriel Eslami, 24, of Trussville, was among the many injured.

“It’s just gun smoke and peoples’ bodies laid out on the pavement,’’ he said. “Physically, it’s hard to walk, but by the Grace of God, it didn’t hit anything major.”

“This included one deceased victim brought to UAB Hospital from the scene, per the Birmingham Police Department,” she said. “We are currently treating 4 victims with conditions ranging from good to critical.”

How did the shooting occur?

Multiple shooters pulled up in a car, Thurmond said, got out and fired shots and then drove away.

The targeted victim in the murder-for-hire was likely found at the scene by the shooters. “Wherever that (targeted) person was is where it was going to take place,” Thurmond said.

Who are suspects in the shooting?

As of Sunday morning, police have not identified the suspects or people of interest.

Was the Hush Lounge involved?

Ryan Pryor, who opened Hush in 2019 and retired after 20 years as a Birmingham police officer in March, was at his club when shots rang out.

“I would like to stress that this had nothing to do with Hush itself. My heart goes out to the families, and I stand with Birmingham on correcting this violence. This gun violence has to stop,” Pryor said.

On Sunday morning, Pryor was preparing to reopen the business.

“We need to try to get back to some kind of normalcy,” he said.

Hush, at 2012 Magnolia Ave., is a speakeasy-style lounge located in the underground space at Pickwick Place retail center. The club often features bottle service, parties, DJs and recently celebrated its fifth-year anniversary in June.
