1805: “I Have Killed Biddy, and Am Going to Deliver Myself Up”: A Hawkesbury Murderer Hanged at Sydney
William Miller, a labourer at Hawkesbury near Sydney, attacked Bridget Horan (also recorded as Kean) with a hoe on the afternoon of 18 September 1805. Minutes later he ran to a neighbour and blurted out the truth: “Yes: I have killed Biddy, and am going to deliver myself up.” He then led the chief constable straight to her body himself, the hoe still lying beside it.
At his trial before the Court of Criminal Jurisdiction in Sydney, Miller pleaded not guilty to acting with malice, insisting the killing had come from unbridled momentary rage rather than intent. The court was unconvinced. He was convicted and hanged on 30 September 1805, his body afterwards handed over for dissection.
Witnesses said Miller never wavered from his confession, going to the gallows with what observers called sincere repentance, seemingly resigned that only his own death could answer for hers.
