The man who "danced on" Robert O'Connor's body after a vicious beating has claimed full responsibility for the murder, the Irish Mirror can reveal.
The thug, who repeatedly stamped on O'Connor's head in a Mountjoy prison cell last summer, is attempting to take the rap - despite three other lags' involvement in the killing too.
The criminal aged in his late 30s made the admission to gardai after he was arrested in jail and questioned.
