Atlanta police are continuing their investigation after an argument led to a deadly bout of gunfire Thursday evening.

One man was dead when officers responded to reports of a person shot in the 3400 block of Martin Luther King Jr. Drive just before 6 p.m., police said in a news release. A second man was waiting to speak with the officers at the scene.

Investigators believe the two men got into an argument that escalated to gunfire. Their names were not released, and it was not clear who fired shots.

The surviving man had not been charged as of Friday morning, police spokesman Officer Steve Avery said in a statement.

“Homicide detectives have identified all involved parties and are investigating the circumstances that led to this incident,” Avery said. “Homicide detectives along with representatives from the Fulton County District Attorney’s Office will determine what, if any, charges are applicable at the conclusion of a thorough and complete investigation.”
