1A newly re-examined photo of Robin Bain's hand could vindicate his son David from killing his whole family, and help him get compensation for the 13 years he spent in prison. In 1995 David Bain was sentenced to life in prison for the murder of his mother, father, two sisters and brother the previous year. After an unsuccessful appeal, the Privy Council quashed David's convictions in 2007 and in 2009 a re-trial found him not guilty, after he had already spent 13 years in prison. David applied for compensation, but Justice Minister Judith Collins found the compensation report to be flawed. For David to get compensation, it needs to be proven that he is factually innocent of the murders. But now a new clue could help prove that his father Robin was the killer.
