Alexander Demonta ’Slugger’ Brown Jr. was 19 when he was shot and killed on Labor Day, Monday, September 3, 2012, on or near Martin Luther King Jr. Drive and 22nd Avenue North in Columbus, Mississippi. Witnesses said a burst of shots rang out about 2:30 p.m.; Brown suffered a single, fatal wound to his eye and head and was rushed by friends to Baptist Memorial Hospital–Golden Triangle, where he died shortly after 4 p.m. Another man, Andre Williams, was wounded in the right shoulder and survived.

Police recovered a handgun and numerous shell casings at the scene and sought two vehicles seen in the area, a maroon Honda and a gold-colored SUV. Within days authorities charged 19-year-old Dominique Chambers with murder and set bond at $500,000. Investigators also sought Devin Thompson, then 20, on counts of aggravated assault tied to the same shooting; later reporting says a grand jury declined to indict him on those charges. Contemporary accounts do not clearly state the ultimate resolution of the murder charge against Chambers.

If anyone witnessed the shooting or saw the vehicles that afternoon, can you share what you know?
