On the night of January 15, 2008, 16-year-old Carlos Alexi Sierra was standing in the vestibule of a building at 16 Strathcona Road in Dorchester when multiple gunshots struck him at about 10:41 p.m. First responders found him with numerous gunshot wounds; he was taken to Boston Medical Center and later pronounced dead. The Office of the Chief Medical Examiner ruled his death a homicide.

Investigators treated the shooting as a targeted attack; another person who was with Sierra was left unharmed. Homicide detectives sought information about a gray or dark green Honda with tinted windows believed to have been in the area. Police noted Sierra’s family had recently moved to the neighborhood and may have had ties to drug activity at their previous residence. No arrests have been announced.

Anyone who knew Carlos, saw that vehicle, or has information about what happened that night is asked to come forward.
