Boston Police report four people were shot in a single incident around 3:50 a.m. on Sunday and that one of the victims died.

Police say the shooting occurred at 7 Edson St. after they received several calls about "a large group of people" congregating in the area. Carl Hentz Belizaire, 21, of Mattapan, was pronounced dead at Brigham and Women's Hospital. He is the neighborhood's 17th murder victim this year (see map), and the 40th murder victim in Boston in 2009. The other three victims, a man, 26, a man, 40, and a woman, 19, are expected to survive.
