Alexander Manning, 52, was shot and killed on the night of February 22, 2015, in the East Flatbush/Flatbush area of Brooklyn. Police found him outside on East 52nd Street near Winthrop Street/Winthrop Avenue about 10:48 p.m.; he was taken to Kings County Hospital and pronounced dead. Investigators described the incident as a street robbery: four teenagers confronted Manning and tried to take his valuables, and when he refused one of the teens fired, fatally striking him.

Reporting at the time said one teen suffered a minor gunshot wound in the same exchange and was in police custody; Gothamist identified that youth as 16-year-old Michael Williams. Detectives were pursuing additional suspects and sought footage from a camera above a daycare across the street. A $2,000 reward was offered for information leading to further arrests.

Did anyone in the neighborhood see the group that night or have footage from a doorbell or camera that could help identify those who left the scene?
