Harvey and Jeanette Crewe were shot and killed in their farmhouse in June, 1970. Their bodies were found in the Waikato River. Arthur Allan Thomas owned a rifle matching the description of the rifle used at the crime scene and was convicted on their murders in 1971. He appealed but a second jury found him guilty in 1973. An innocence campaign led by the Auckland Star prompted Prime Minister of New Zealand Rob Muldoon to overturn Thomas’s conviction in 1979. No further individuals were charged with the Crewes’ murders and the case remains unsolved.
