The murder of Co Armagh trucker Paul Quinn will be debated in the Dáil later today.
Government and Opposition TDs will read statements into the parliamentary record on last October's killing.
Mr Quinn (21), was beaten to death by a gang of about a dozen men in a remote shed in Co Monaghan. No arrests have yet been made.
Mr Quinn's parents have blamed the IRA for the death of their son, whom they claimed had defied orders to leave the country by the terrorist group.
However Sinn Féin denied any republican link and said the death was sparked by a feud between rival criminal gangs involved in fuel smuggling.
Parents Stephen and Briege Quinn have mounted a campaign to bring those responsible to justice and have met many politicians, including Taoiseach Bertie Ahern and Fine Gael leader Mr Kenny.
Mr and Mrs Quinn and supporters are expected to observe the Dáil debate from the public gallery.
Gardaí are pursuing 1,200 lines of inquiry into the murder and have taken more than 400 statements.
