On the morning of Saturday, November 25, 2023, Marco Alfonso Sosa, a 32-year-old Hispanic man from Lynn, Massachusetts, was fatally shot in a parking lot between 12 Glenville Avenue and 161 Harvard Avenue in Allston, Boston. The shooting occurred around 2:25 a.m. A second man suffered non-life-threatening injuries and both victims were first flagged to police when they arrived at a local hospital.

Sosa was pronounced dead at the scene and the Boston Police Homicide Unit opened an active investigation. As of late 2023, no arrests had been announced. Family remembered Sosa as a beloved son, a devoted father to his young daughter, and a cherished brother; a memorial service was held December 3, 2023, at the Ruggiero Family Memorial Home in East Boston.
