A Virginia state trooper’s speed gun has helped federal investigators unravel a firearms smuggling ring with a pipeline to the District of Columbia’s street gangs, authorities told The Examiner.

Michael “White Boy” Lewis and Troy Burke were indicted on federal conspiracy and weapons charges earlier this month, court papers show. They are accused of stealing at least 60 guns from Virginia gun shops and selling them to couriers, who in turn sold them on D.C.’s streets.
