Thomas Woolcock died at 3 am on 4 September 1873 in Moonta, Adelaide having suffered weeks of stomach pains, nausea, and prolonged vomiting. His death was initially attributed to exhaustion, but suspicion quickly fell on his wife Elizabeth Woolcock, a woman whose own life had been marked by hardship, abuse, and desperation.
Elizabeth had endured years of violence at the hands of Woolcock, a heavy-drinking wife-beater who had repeatedly prevented her from leaving. In the weeks before his death, she had made increasingly frantic attempts to obtain morphine and other substances from local chemists, and her behaviour had become talk of the community. Charged with murder by mercury poisoning, Elizabeth was tried, convicted, and hanged at Adelaide Gaol on 30 December 1873. She remains the only woman ever executed in South Australia.
