Three men will spend the rest of their lives in prison for the deadly gun violence that started over a piece of costume jewelry and culminated in one of the worst mass shootings in the District’s history.

Orlando Carter, 22, Jeffrey D. Best, 23, and Robert Bost, 23, were sentenced Tuesday to life in prison without the possibility of parole for the murders of five young people and the wounding of nine over eight days in the spring of 2010.
