Atlanta police released a video Friday in hopes of generating leads in a homicide investigation.

One person was killed and another injured in a shooting Saturday about 9:30 p.m. in a vehicle near the intersection of McDaniel and Glenn streets in southwest Atlanta on Saturday, police said.

The deceased was identified by police as 21-year-old Nicholas Green, who was riding in an orange 2005 Infinity driven by his brother, Rahmir Melton.

According to police reports, Melton told police that a new gray Hyundai pulled up beside his SUV and began shooting. After the shots, Melton drove to Children’s Healthcare of Atlanta at Hughes Spalding a couple of miles from the shooting site. It was there that Green died.

Green’s body and the injured Melton were taken soon thereafter to Grady Memorial Hospital.

The video shows Lt. Charles Hampton, homicide commander for Atlanta police, narrating security camera footage from a convenience store. He said the surveillance footage shows Green outside of the store right before his brother pulled up to pick him up. He added that it also shows individuals in the store who police believe may have information on the incident or what led up to it.

“This is the last time that we know of that our victim was alive. We’re asking if anyone knows the individuals on this video,” Hampton said. “We’re asking the community to reach out to us so we can further our investigation.”

Hampton said it is unknown if the people shown in the video were involved in any way. Authorities, he added, are currently considering them potential witnesses.

Additional surveillance camera footage shown by police shows someone running to a car that looks like a Hyundai Sonata. Later footage appears to show the same vehicle alongside Melton’s SUV.
