Federal authorities say 48 members and associates of Boston's largest and most powerful gang have been indicted on drug and gun charges.

Authorities said at a news conference that members and associates of the Columbia Point Dawgs were indicted Thursday. Seven remain at large.

They say the gang started operating out of the Columbia Point housing project in the Dorchester section of Boston in the 1980s, eventually trafficking drugs from Boston to Maine.

They say the gang's infiltration of drug trafficking territories held by rival gangs led to numerous killings. They cited the 1990s killing of a member who was shot while sitting in Whitney Houston's Bentley with her husband, Bobby Brown

A rival gang member was convicted.
