Police are looking for a gunman who fired into a crowd in Boston, injuring five people including a child. The shooting happened Wednesday night as a crowd was gathered in the city's Dorchester section. An 11-year-old child, a 21-year-old man, a 20-year-old man, a 21-year-old woman, and a 20-year-old woman were shot but none had injuries that were considered life-threatening. Mayor Michelle Wu, who visited the scene, said the city “has a lot more work to do” to stem the violence. Police did not say what may have led to the shooting.
