Michael O'Brien, wrongly jailed for 11 years for the 1987 murder of Cardiff newsagent Phillip Saunders, says he won’t rest until the real killer is found.
Now 57, O'Brien was convicted despite no forensic evidence and later acquitted in 1999.
He still suffers from PTSD and campaigns for justice.
Following the release of Peter Sullivan after 38 years, O'Brien renewed calls for accountability and support for victims of miscarriages of justice.
