A man has been arrested and faces murder charges nearly four weeks after a deadly shooting at a DeKalb County nightclub, investigators said Monday.

Quincy Tyler Walker, 26, of McDonough, was arrested Sunday at a Buford Highway restaurant, according to the DeKalb County Sheriff’s Office. He faces felony murder charges and two counts of aggravated assault.

On Oct. 25, Walker allegedly shot two security guards, killing one, at Cosmopolitan Premier Lounge in Decatur. The guards had attempted to break up a fight at the Glenwood Road nightclub before they were shot in the parking lot shortly before 2:30 a.m., a DeKalb police spokesperson previously said.

“It appears that there was a dispute inside the club when everyone was told to exit the location,” Officer Elise Wells said in a statement. “The suspect then began to fire shots outside the location, striking two security guards.”

Erik McKenzie was killed in the shooting, which injured Ronald Folkes, the sheriff’s office said.

McKenzie, 30, was a New York native who had moved with his family to Lithonia, according to his online obituary. After graduating from Lithonia High School in 2010, he played football for Savannah State University.

“Erik took his passion for protecting others and turned it into a lucrative business of providing security services to those within the entertainment industry,” his obituary states. “He passed away doing what he loved.”

Walker was being held without bond Monday at the DeKalb jail, booking records show.
