Emerson Green, 25, was shot to death on September 6, 2016, on a residential street in South Daytona, Florida, just behind the police department. He died of multiple gunshot wounds and his body was found shortly after the shooting.

Investigators have not identified suspects or made arrests, and law enforcement has released few details about the investigation. The case remains unsolved, and Green’s family has expressed frustration over the lack of progress. His older sister has publicly said she believes he was set up, though no evidence supporting that claim has been made public.

Anyone who has information about Emerson Green’s death or who was in the area that night is asked to come forward.
