Imagine losing almost forty years of your life? The chance to. have children, a career, homes, holidays - four decades worth that never existed. Peter Sullivan was freed from jail this week after serving 38 years for a crime he didn't commit. He maintained his innocence throughout despite being convicted of the murder of 21 year old Diane Sindall in 1987. All down to modern DNA that proved it wasn't him but his cries for help, for a review were turned down time and again. Martin Frizell and emeritus Professor of Criminology David Wilson try to make sense of Britain's longest miscarriage of justice.
