was the last person to be hanged in the state of Western Australia. He was buried in Fremantle Cemetery, above the remains of child killer Martha Rendell, who was hanged in Fremantle Prison in 1909. Wrongful convictions Two of Cooke's murders resulted in other men being falsely convicted of them: Beamish case Darryl Beamish, a deaf-mute, was convicted in December 1961 of murdering Jillian Macpherson Brewer, a Melbourne heiress who was struck with a hatchet and stabbed with scissors, in 1959. Beamish was initially sentenced to death, but the sentence was commuted to imprisonment, and a later investigation, supported by Post Newspapers owner Bret Christian led to his conviction being overturned. Beamish's initial appeal was dismissed because the court did not believe Cooke's evidence. The prosecution claimed that Cooke's confessions were an attempt to prolong his own trial, and the then-Chief Justice of Western Australia, Sir Albert Wolff, called Cooke a "villainous unscrupulous liar". The police case against Beamish is detailed in Christian's book Presumed Guilty. Button case John Button was wrongly convicted for the death of his girlfriend, Rosemary Anderson, who died in Royal Perth Hospital (RPH) at 2:30am in the early morning of 10 February 1963. Anderson had spent the previous day with Button in celebration of his nineteenth birthday; they had a minor argument at his home that night which culminated in her deciding to leave the Button house and walk home. Button followed her in his car at different stages, attempting to have her accept a lift home. At one stage Button parked his car to smoke a cigarette; upon resuming driving he turned into Stubbs Terrace, in Shenton Park, and discovered her lying on the ground beside the road. John Button took his injured girlfriend to a local doctor and she was subsequently transferred to RPH by ambulance. The police became involved and interviewed Button who, after intense questioning and upon receiving notice of Anderson's death, broke down and confessed to being responsible for her hit & run death. After conviction for manslaughter, the courts dismissed Button's initial appeal, even though Cooke had by this time confessed to the crime and provided details that only the culprit could have known; in particular, the judges did not believe Cooke's claim that Anderson's body was thrown "over the roof" of a Holden EK sedan without damaging its external windscreen sun visor, as Cooke had claimed.
