The nationwide hunt for the accused killer grandma escalated big time. Giant new billboards are going up in Texas, New Mexico, Arizona and California. They feature the face of 56 year-old Lois Reiss, who is being sought for the slaying of her lookalike in Fort Myers, Florida. The U.S. Marshals Service assumed command of the search. New images show a middle-aged woman robbing a bank in Pasadena, California. She's wearing a hat and glasses and is about the same age and body type as Lois Reiss.
