Atlanta police have charged a suspect in a deadly shooting outside Lenox Square. But the suspect is not yet in custody, police said Friday afternoon.

Thuan Nguyen, 31, was shot and killed Sunday after what investigators believe was a dispute over a parking space. The Tennessee man was shot in the head and died at the scene.

Earlier this week, police released surveillance images of three people possibly involved with the shooting. On Thursday, arrest warrants were issued, charging one person with felony murder, Officer Steve Avery said. The suspect’s name was not released.

“Our Fugitive Unit is actively working to take him into custody,” Avery said in an emailed statement Friday afternoon.

Sunday’s shooting was the fourth in as many months outside the Buckhead mall. In an emailed statement to The Atlanta Journal-Constitution, Simon Malls, which operates Lenox, said additional safety measures have been put in place since the shootings began.

“We have more than tripled our security and police presence at Lenox Square. Sixteen security and police personnel were on property at the time of the incident,” Simon Malls said. “Recent incidents that have impacted both the area and the surrounding community are reflective of broader societal trends that are unacceptable and we are working relentlessly with community leaders to address.”

Atlanta police have a precinct at the mall. Chief Erika Shields has called the brazen violence “deeply concerning.”

“We will not, under any circumstances, allow lawlessness to destroy one of Atlanta’s most beloved and long-standing retail institutions,” Shields said.
