A person suffered life-threatening injuries Monday night in a South Boston shooting.
"I heard this huge bang, it sounded too muffled to be a gunshot, so I thought, 'Oh, maybe it was a little firework,'" said Brendan McCarthy Jr., who was about to walk his dog, Bailey.
Police blocked off a huge portion of Dorchester Street while they investigated the shooting.
