A onetime Chesapeake resident who was convicted for his role in a family spy ring has died in a federal prison in North Carolina. Arthur Walker was 79. Federal Bureau of Prisons spokesman Chris Burke says Walker died recently in Butner, North Carolina. Walker was convicted of stealing secret documents from a defense contractor and giving them to his younger brother, John Walker for delivery to the Soviet Union. John Walker pleaded guilty in 1985 along with his son, Michael Walker, to charges of spying for the Soviet Union. Michael Walker was released in 2000.
