The parents of Paul Quinn from Cullyhanna Co Armagh who was killed by a group of men in Co Monaghan last month have appealed to those responsible to give themselves up to the gardaí.
The 21-year-old died after he was beaten to death by a group of men in a shed after he had been lured there.
Briege and Stephen Quinn said they were hurt by remarks made by the Taoiseach in the Dáil that their son's death was linked to a feud about criminality.
They say senior IRA figures were involved in the murder.
The gardaí are leading the investigation in co-operation with the PSNI, but so far nobody has been arrested or charged.
