In October 1985 Arthur Easton was murdered in his Papakura family home. Easton and his two teenage sons were attacked by a bayonet-wielding home invader. The 52-year-old postal worker was stabbed in his liver during the frenzied attack and died of blood loss after emergency services arrived on the scene. Alan Hall was convicted of murder in 1986 and spent 19 years in prison for the crime. However Hall was not the person who killed Easton. He maintained his innocence for almost four decades and in 2022 the Supreme Court finally quashed his conviction for murder. The Crown accepted earlier this year in a submission to the Court that key evidence leading to the identity of the true attacker was "materially" altered, leading to a miscarriage of justice. Today Herald senior journalist Anna Leask revisits the murder of Arthur Easton and the journey to justice for Alan Hall.  This episode of A Moment In Crime is a bonus episode.
