Hundreds of mourners paid their respects at the funeral of Co Armagh man Paul Quinn today.
At a requiem mass in St. Patrick's church in Cullyhanna, Father Kevin Cullen said they were there to "remember one so young, so ruthlessly taken from them".
He described the killing as "a barbaric crime that was deeply sinful".
The family of the 21-year-old has blamed IRA members for Paul's death, but Sinn Féin has denied any republicans were involvement.
Paul Quinn was beaten to death by a gang of men at the weekend, after being lured to a farm near Oram in Co Monaghan.
