A 61-year-old Pennsylvania woman was found guilty Monday of armed robbery, conspiracy, and using a destructive device after she masterminded a plan with five men to rob a PNC bank in 2003. Marjorie Diehl-Armstrong convinced one of the men to disguise himself as a pizza delivery man with a bomb strapped around his neck. Brian Wells, 46, walked out of the local bank with $8,702 dressed as a delivery man with a detonating device around his neck. But when police arrested him shortly after, the device exploded, killing Wells. Diehl-Armstrong is already serving 20 years in prison after she pleaded guilty and mentally ill for killing her boyfriend.
