A man was shot and killed at a southwest Atlanta home early Tuesday after a deal to sell a gun went sour, police said.

The man was found dead just before 1 a.m. after a gunshot was fired inside the home in the 2700 block of Third Avenue.

At least two men planned to meet at the home to complete the sale of the weapon, police spokesman Officer Jarius Daughtery told AJC.com. At some point during the transaction, there was an argument “that escalated to a shot being fired,” he said.

The other man initially left the scene, but Daugherty said he later returned and is cooperating with investigators.

Police have not settled on a motive as the investigation is ongoing.

“We want to see exactly what occurred, what the dispute was about,” Capt. LeAnne Browning said Tuesday from the scene. “So we’re looking at every single angle that this dispute possibly could have involved.”

No charges had been filed as of Tuesday afternoon, according to police.
