On the evening of Thursday, August 13, 2015, 21-year-old Isaiah Cicero was shot in front of an apartment building on Saratoga Avenue in the Brownsville neighborhood of Brooklyn. Two other men, ages 18 and 20, were wounded and survived. Cicero was taken to Brookdale University Hospital and Medical Center but died of a gunshot wound to his torso.

Police described the attack as not random and believed it to be gang-related, a characterization disputed by Cicero’s mother, who said he was not involved in gang activity. Surveillance video released by investigators shows a masked person holding a door open and firing into the building foyer, but the shooter’s identity remained concealed by the mask. A year after the killing the family publicly appealed for information; no arrests had been announced.

If anyone has information about that night or recognizes the person in the footage, please come forward.
