Mr Irwin said:
‘‘The murder of Paul Quinn was a cruel and barbaric act yet with a clinical crime scene clean-up. It is sickening that not a major bone in Paul’s body was left unbroken, such was the extent of his injuries.
The monsters responsible for this heinous crime would not look out of place in some of the world’s most evil and oppressive regimes. Sinn Fein must encourage all republicans to tell the truth about the murder. Sinn Fein claims to oppose an amnesty but they have let down the Quinn family time and time again.
I welcome the fact that the police investigation into this murder remains a live process. Investigators have a duty to exhaust all lines of enquiry, regardless of where - or to whom - that leads.
New developments in this case are testament to the relentless campaign for truth and justice led by Breege and Stephen Quinn. The courage and dignity they have displayed throughout stands in stark contrast to the perpetrators of this evil and their protectors.”
