 Parr took Bury upstairs to see Lieutenant David Lamb , the head of the detective department . Parr told Lamb , " This man has a wonderful story to tell you . " Bury retold his story to Lamb , but omitted the reference to Jack the Ripper , and added that he had stabbed his wife 's body once . Bury was searched , and a small knife , bankbook and his house key were confiscated pending inquiries . Lamb and Detective Constable Peter Campbell proceeded to the Burys ' dingy flat , where they discovered the mutilated remains of Ellen stuffed into the wooden box Bury had commissioned in London .
