FILE - In this Jan. 23, 1951 file photo, Peter van der Hurk, also known as Peter Hurkos, who claims to have aided police in several major crimes, is pictured on his arrival at the airport in London to aid Scotland Yard in their search for the missing Coronation Stone, or the Stone of Scone. Casting is underway in summer 2016 for 'Stranglehold,' a new movie about the Boston Strangler that will focus in part on Hurkos, who helped investigators search for clues for nearly a dozen unsolved murders of women in the 1960s.
