A Pennsylvania nurse aid is being accused of stealing rings from the hands of an elderly patient. Police say 39-year-old Christina Ankney is being charged with robbery after she pried an engagement and wedding ring off the hands of a patient suffering from dementia in Murrysville. Those rings were later found at a local pawn shop. Ankney is also wanted for another theft, a case stemming from her stealing mail when she worked for the U.S. Postal Service. A warrant has been issued for her arrest.
