Harold Breion Long, 19, was killed in a drive-by shooting in a Mayport neighborhood on July 14, 2014. Neighbors reported hearing gunshots, and police found Long’s body in a backyard on Cypress Landing Drive. Investigators say the shots came from someone in a passing car; the motive has not been established.

No arrests have been announced and the case remains unsolved. Long’s brother Marquis Curry has publicly urged witnesses to come forward; in 2021 a witness provided details that gave the family hope, but the investigation has not produced charges or a resolution.

Anyone who was in the Mayport area around Cypress Landing Drive on July 14, 2014, or who has information about a vehicle or people seen leaving the scene, is asked to contact the Jacksonville Sheriff’s Office.
