Peter was one of the last men to be sentenced to hanging in Ireland, convicted of murdering two Gardaí in 1980. His death sentence was commuted to 40 years in prison. During his prison stay he discovered evidence of a blood sample of his that had not been examined in his trial. In 1995 he succeeded in an appeal against his conviction and since then met and married Sunny Jacobs with whom he lives with in the west of Ireland.
