Byren Cook, 24, was fatally shot on the evening of January 23, 2017, in the Harbour House neighborhood of Annapolis. Police responded to reports of shots fired on Madison Street shortly before 8:30 p.m. and found Cook in the 1100 block of Madison Street with gunshot wounds; he was transported to a hospital and later died.

Detectives developed a lead that the shooter was inside an apartment in the 1200 block of Madison Street and obtained a search warrant. Among the people found inside was 18-year-old Marique Jackson of Annapolis, whom investigators identified as the shooter. Jackson told investigators he had seen Cook carrying a shotgun as Cook left the complex and fired a 9mm pistol, discharging several rounds before leaving the scene. Police recovered the suspected murder weapon and a gun that had been in Cook’s possession.

Jackson was arrested and charged with first-degree murder and related offenses. A 15-year-old Annapolis girl was charged as a juvenile with accessory after the fact and obstructing justice and later released to a guardian. Authorities noted a possible link to the illegal drug trade; court records also show Jackson faced two misdemeanor marijuana possession charges weeks earlier. Any readers with information about Cook, the Harbour House area that night, or the events leading up to the shooting are asked to share what they know.
