Jeromie Johnson was 33 when he was mortally wounded in a shooting on Richfield Street in Dorchester on the evening of April 8, 2015. He was sitting in a vehicle when gunfire erupted; he was taken to Boston Medical Center with life-threatening injuries and died about a month later. Another man in the car, identified as Victor Arrington, was also shot but survived.

Investigators quickly drew a possible link between Johnson’s shooting and a violent home invasion on March 31, 2015, in which multiple people were shot and a fire was set. Detectives found frequent communications between Johnson and Arrington, and police seized cell phones from the scene and from Arrington’s property at the hospital. A cooperating witness later identified Arrington as involved in the March 31 incident, and Arrington was indicted in connection with that home invasion. The shooter or shooters who killed Johnson have not been publicly identified, no arrests have been announced in his murder, and the case remains unsolved.

Anyone with information about the April 8 shooting or Johnson’s movements in Dorchester that spring is asked to come forward.
