It seemed the situation was diffused when one of the vehicles drove away. Then the vehicle, a Honda Accord, returned, and police said a passenger got out and fired several rounds, hitting the victim in the head.

“He was just trying to help squash an altercation between two individuals and ended up getting shot,” Spencer said.

The vehicle took off shortly after the shooting.

DeKalb County SWAT searched a home in a nearby neighborhood, and Aden Osman Bouh was arrested on an aggravated assault charge, according to Channel 2 Action News

Bouh was identified as the driver of the vehicle, police told Channel 2. A second man was taken into custody for questioning but was not charged.

Police are still investigating what led to the confrontation.

No other details have been released.
