Marquise Byfield was 16 and from Brooklyn when he was shot and killed on the afternoon of April 24, 2026, after a confrontation that followed him into Livonia Deli & Grocery at 909 Livonia Avenue in East New York. Police arrived after a 911 call at about 4:16 p.m. and found Marquise with gunshot wounds to his torso and groin; he was taken to One Brooklyn Health-Brookdale University Medical Center in critical condition and later pronounced dead. Reports disagree on the exact number of times he was struck, with some saying several shots and others saying at least two.

Witnesses and the store owner described a chaotic scene. The owner said Marquise and another teen were fighting when they entered; one teen reportedly had a knife, and the other appeared frightened before producing a gun and firing. Employees dropped to the floor as shots rang out, and a vigil soon formed outside the deli as friends left candles and handwritten messages. Anyone with information is asked to contact Crime Stoppers.

Did anyone in the neighborhood see what happened inside the store or know the identities of the teens involved?
