On the evening of March 20, 2020, 18-year-old Vincent Lewis-Coppin Jr. was found with life-threatening injuries after a shooting in Mattapan. Police discovered him at 86 American Legion Highway just after 7:30 p.m.; he had been shot in the chest and was taken to a local hospital where he was pronounced dead. Known to friends as Swervo, he was awaiting the birth of his first daughter.

Earlier that year, on January 26, 2020, Lewis-Coppin had survived a separate chest shooting in West Paris, Maine. He called police after that incident and was flown to a medical center, released later that week and did not cooperate with the investigation. Authorities in Maine arrested John Crouch III on an attempted murder charge and detained Angelique Henderson on suspicion of conspiracy, though she was later released for insufficient evidence.

There is no indication those arrests are connected to the Boston killing and no public information about suspects or arrests in the Mattapan case. Does anyone have information that could help Vincent’s family and investigators?
