Nick Yarris spent 22 years on death row for a murder he didn't commit -- before he finally walked out of prison a free man in 2004. He was wrongly convicted in the 1982 case of a woman who was raped and murdered in the US state of Delaware, but eventually acquitted when DNA evidence proved that he was not the killer. Yarris later moved to the UK, and now lives in Los Angeles, from where he spoke to Peter Bowes & Rhod Sharp on BBC Radio 5 live's Up All Night programme.
