“Ant Live” and “Mr. T,” two Poughkeepsie, N.Y., drug dealers, confronted the Mann brothers, two out-of-towner dealers who were poaching on their turf, and gunned them down on Nov. 18, 1995.

“Ant Live,” the street name used by Anthony L. Reed, killed one Mann brother, and “Mr. T,” whose real name is Raymond Earl Warren, killed the other.
