The family of the only prison officer murdered in the Republic are hopeful of getting to the bottom of the killing after meeting Gerry Adams, they said.
Austin and Oliver Stack, whose father Brian was gunned down outside the National Stadium in Dublin three decades ago, held talks lasting more than an hour with the Sinn Fein leader at Leinster House yesterday.
They believe they know the identity of the killer, his getaway driver and a senior IRA figure they say sanctioned the assassination, and have urged Mr Adams to put pressure on republican colleagues to confess anything they know.
"It was a very good and productive meeting," said Austin Stack afterwards.
The Stack family and Mr Adams have agreed to meet again within a month to see if any progress has been made in their quest for answers about their father's death.
