On 5 April 1932, Dorothy Ruth Denzel and Frank Barnby Wilkinson, a young couple soon to be engaged, were attacked and killed while resting on a rug in a darkened lane near Liverpool, NSW. Their killer, William Cyril Moxley, a police informer with a criminal record, fled the scene in Wilkinson's red Alvis sports car, later found abandoned in Ashfield. Moxley was identified in part by a distinctive detail: a clean bullet hole through his left ear, a souvenir from criminals he had once informed on.
A massive manhunt followed, with more than a hundred police deployed and families in surrounding suburbs locking their homes at night. Moxley was eventually tracked to bushland at Frenchs Forest in Sydney. He tried to escape, but after a chase and struggle involving three police officers, he was overpowered and arrested. He was hanged at Long Bay Gaol on 17 August 1932.
