In 1963, Perth serial killer, Eric Edgar Cooke, confessed to the murder of Anderson when arrested in 1963 and again before he was executed.
At his appeal, Trevor Condron, the police officer who had examined John Button's car in 1963 told the appeals court that while the car was damaged, the damage was not consistent with hitting a person and that three weeks before Anderson's death, Button had reported to police another accident.
The world's leading pedestrian accident expert, American William "Rusty" Haight, was flown to Australia and testified that experiments with a biomedical human-form dummy, a similar Simca to Button's and an EJ Holden similar to the one Cooke claimed he was driving when he hit Anderson, matched exactly Cooke's account and excluded the Simca.
[10][11] Button now spearheads the Western Australian Innocence Project, which aims to free the wrongfully convicted.
He was spared further incarceration at this time, due to intervention from the Radical Party which offered him a candidacy to the European Parliament (EP).
He returned the next year to his work in TV to a moving comeback in his "Portobello" show, only to die in 1988 from cancer and become an icon of battles against injustice and a perpetual reminder of a grave public blunder of the Italian judiciary system.
In 2015, the Supreme Court of Cassation overturned the previous guilty verdicts, definitively ending the case.
The group declared her a prisoner of conscience, claiming there was no credible evidence against her, and that she had been prosecuted because of her gender, poverty, race, and inability to speak or understand the Spanish language.
[100] In the 2010's, public interest in addressing the possiblity of wrongful convictions as a system issue led to the establishment of the Criminal Cases Review Commission in 2019.
[107] The case came under scrutiny after two of the four alleged witnesses to the crimes recanted their testimony, claiming that the police had pressured them into lying.
The other two were men who had admitted to participating in the rape of Leah Stephens and had been granted immunity in return for their testimony.
[113] After returning to the U.S., St. Martin's Press published Volz's memoir, Gringo Nightmare: A Young American Framed for Murder in Nicaragua.
