Seneca W. McCullough, 35, was killed after being lured to an abandoned brownstone in Bedford-Stuyvesant on August 20, 2014. A dispute with 23-year-old Joseph Hutcherson of East New York preceded the killing; Hutcherson asked to meet McCullough at the Quincy Street building, which served as a Gates Avenue Mafia stash house. McCullough arrived at about 12:45 a.m., was led into the basement, beaten, and shot in the lower spine and the back of the head. He was taken to Woodhull Hospital, where he was pronounced dead.

Investigators traced Hutcherson after he hid in a Coney Island apartment and was recorded discussing the shooting on a tapped phone; a witness at trial also said Hutcherson confessed to his mother. In December 2017 a Brooklyn jury found Hutcherson guilty of murder and criminal possession of a weapon; in January 2018 he received a sentence with a minimum of 23 years.

Was anyone in Bedford-Stuyvesant or East New York at the time aware of tensions between these men or of unusual activity around that brownstone?
