Alvin Sealey Jr. was 19 when he was shot to death on a Dorchester street in the early hours of January 27, 2016. He was found near Washington Street and Dunbar Avenue with a fatal gunshot wound to the head and was pronounced dead at the scene, recorded as Boston’s third homicide of that year.

Known as Trizzy to friends and family, Alvin worked two jobs and played the piano. His father, Alvin Sealey Sr., described him as a happy young man who got along with everyone. Investigators have said Alvin appeared to have been targeted rather than randomly attacked, but despite homicide detectives working the case, no suspects or arrests have been announced and the investigation has gone cold.

Anyone who was in Dorchester that night or who knew Alvin and might have information is asked to contact the Boston Police homicide unit or the anonymous tip line.
