Police searching the house at Wardle Brook Avenue found an old exercise book with the name "John Kilbride", which made them suspect that Brady and Hindley had been involved in the disappearances of other youngsters. Brady told police that he and Evans had fought, but insisted that he and Smith had murdered Evans and that Hindley had "only done what she had been told". Smith said that Brady had asked him to return anything incriminating, such as "dodgy books", which Brady then packed into suitcases; he had no idea what else the suitcases contained or where they might be, though he mentioned that Brady "had a thing about railway stations". A search of left-luggage offices turned up the suitcases at Manchester Central railway station on 15 October; the claim ticket was later found in Hindley's prayer book. Inside one of the cases were—among an assortment of costumes, notes, photographs and negatives—nine pornographic photographs taken of Downey, naked and with a scarf tied across her mouth, and a sixteen-minute audiotape recording of a girl identifying herself as "Lesley Ann Weston" screaming, crying, and pleading to be allowed to return home to her mother. Downey's mother later confirmed that the recording, too, was of her daughter.
