Tamon E. Choate was 18 when he was fatally shot in Boston’s Dorchester neighborhood on May 4, 2009. Officers found him on the sidewalk of Tonawanda Street at about 7:19 PM with a gunshot wound; he was taken to Boston Medical Center and pronounced dead shortly after arrival.

Witnesses reported hearing multiple gunshots and saw two people running from the scene toward Waldeck Street. Despite those initial leads, no arrests have been announced and the homicide remains unsolved. The killing heightened concerns about youth violence in the city and devastated Choate’s family and community.

Can anyone who was in the Dorchester area that evening or who has information about people seen near Tonawanda or Waldeck Street come forward?
