The Suffolk district attorney says a body found fatally stabbed on an East Boston beach on Labor Day was that of a 15-year-old boy.
District Attorney Daniel Conley identified the victim on Tuesday as Wilson Martinez of East Boston.
Conley said a man walking near the East Boston Yacht Club on Constitution Beach at 8 a.m. saw Martinez's body along the waterline.
Conley said "no piece of information is too small to be helpful" as state police investigate the teenager's death.
Anyone with information is urged to call investigators at 617-727-8817.
State police assigned to the district attorney's office are investigating. They have jurisdiction on the beach, which is state recreation land.
