Darrell Harrell, 45, was shot and killed on December 16, 2008, in Miami’s Overtown neighborhood. He was reportedly trying to remove drug dealers from the area, a role that investigators say made him a target. Detectives Sgt. Altarr Williams and Frankie Sanchez were among those who worked the homicide; the case was profiled on an episode of The First 48.

Investigators encountered setbacks during the early probe and the investigation eventually went cold with no arrests. Authorities continue to seek information that could lead to solving the killing.

If anyone knew Harrell, saw activity in Overtown around December 16, 2008, or has information relevant to this case, please come forward.
