At about 9:47 PM on Tuesday February 27, 2018, an officer assigned to District E-18 (Hyde Park) was flagged down while on patrol in the area of Fairmount Avenue and Truman Parkway by a victim who stated that he had just been carjacked at gunpoint. The victim stated that he had been forced out of his vehicle by three male suspects in the area of 577 River Street and that one of the males had brandished a firearm during the incident. The officer searched the area and quickly located the stolen vehicle parked and occupied in an alley behind 771 Truman Parkway. Upon seeing the officer approaching, the three suspects simultaneously exited the vehicle and fled on foot through nearby backyards. The officer pursued one of the suspects on foot, later identified as Joquentz Constant, 21, of Dorchester, and placed him in custody in the area of 11 Williams Avenue with the assistance of additional responding units. Officers then set a perimeter while BPD K-9 Duke arrived on scene and began to search for the two remaining suspects. Duke soon located, Marckenley Casimir, 27, of Mattapan and Hermano Joseph, 27, of Randolph, hiding on a deck in the rear of 755 Truman Parkway at which time they were placed in custody without further incident. It was later determined that Casimir was wanted on two outstanding warrants sought out of Suffolk Superior Court for Armed Assault to Rob and Assault with a Dangerous Weapon. During their continued search efforts, officers recovered property belonging to the victim as well as a replica firearm and other evidence related to the investigation in the area of 767 Truman Parkway. All three suspects will appear in West Roxbury District Court on numerous charges including Carjacking, Armed Robbery and Kidnapping.
