ATLANTA - Atlanta Police have released a new video as evidence in the search for a killer in northwest Atlanta.

The video shows four people police have identified as persons of interest in the Aug. 26 murder of Dedrell Knox.

Knox was found lying in the grass in front of an apartment complex on the 900 block of Desoto Street with several gunshot wounds.

Investigators say a fight began inside the unit, spilled outside, and ended in gunfire.

They believe it may have been drug-related.
