Elizabeth Woolcock

Elizabeth Lillian Woolcock (née Oliver; 20 April 1848 – 30 December 1873) was an Australian murderess who was hanged in Adelaide Gaol for the murder of her husband Thomas Woolcock by mercury poisoning. She remains the only woman ever executed in South Australia and is buried between the outer and inner prison walls of Adelaide Gaol. It has been argued that she may have been a victim of domestic violence and suffered from battered spouse syndrome. Provided by Wikipedia
