Fifteen people have pleaded guilty for their roles in a prison contraband scheme in Maryland that included the use of drones to smuggle drugs, cellphones and other items into a state prison, the state's attorney general announced.
The guilty pleas came seven months after Attorney General Anthony Brown first announced that a correctional officer and civilians had been indicted on charges that they assisted inmates in illegal activity at the Roxbury Correctional Institution in Hagerstown, Maryland.
