On the morning of June 21, 2018, gunfire erupted around 9:40 a.m. on Castle Hill Avenue in the Bronx. Christopher Alleyne, 33, was struck in the head during a sudden daytime attack in front of a strip of businesses and taken to Jacobi Medical Center, where he was pronounced dead.

The shooting was a triple homicide. Mustafa Tarver, also 33, was shot in the head, and 45-year-old Arileida Jimenez, reportedly an innocent bystander handing out flyers, was shot in the torso. All three victims lived in the nearby Castle Hill Houses and died of their injuries at the hospital. Witnesses tried to help the victims before emergency crews arrived.

Police identified 51-year-old Samuel Cross as a suspect and released surveillance footage of him fleeing the scene; investigators believe Tarver was the intended target and Alleyne, known as Butter, an unintended victim. A reward was offered and the case was publicized, but as of 2022 no arrests had been made and the investigation remained active.

If anyone has information about what happened that morning or the suspect seen fleeing, please share it with investigators.
