John Allen Muhammad was sentenced Thursday to six consecutive life sentences for the October 2002 killings of six people during a sniper shooting spree that terrorized the Washington, D.C. region. "You, Mr. Muhammad, have no hope. You have no future. You will spend every day for the rest of your life locked in a cage," said Montgomery County Circuit Judge James Ryan. Muhammad showed no emotion, but stood with his head bowed as the sentence was announced. Some in the audience applauded. Muhammad is already on death row in Virginia for another sniper killing. Maryland prosecutors have said the additional life sentences are insurance if the Virginia conviction is ever overturned.
