James Mason, 45, was found shot to death around 1 a.m. on April 14, 2014, on a sidewalk near the corner of Dabney Street and Regent Street in Roxbury’s Warren Gardens area, close to his apartment. Boston Police discovered him after a call about a person being shot; it is unclear how long he had been lying there before being found.

Mason was a father of two and a grandfather. Family members described him as a loving man who mostly kept to himself, recalled episodes of depression they tied to past football concussions, and said he often took walks at night to listen to music and clear his head. His sisters contend he had no known enemies and believe he was walking that night.

No arrests or publicly identified suspects have been announced and the case remains unsolved. If anyone knew James, saw activity near Dabney and Regent the night of April 14, 2014, or has information that could help, please come forward.
