The son of murdered prison guard Brian Stack said it was “scandalous” that Sinn Féin leader Gerry Adams has not been questioned by gardaí about the brutal murder.
The Irish Independent recently revealed Mr Adams last year sent an email to Garda Commissioner Noirin O’Sullivan naming Sinn Féin members who may have information on Mr Stack’s murder.
It has since emerged gardai plan to question Mr Adams about the names he claimed he received from Mr Stack’s son Austin. Austin Stack has categorically denied he gave the name to Mr Adams.
Speaking before a meeting with Taoiseach Enda Kenny, Austin Stack said he was concerned that Mr Adams had not been questioned by gardaí at this stage.
Afterwards Mr Stack and his family said they received assurances from Mr Kenny and Tánaiste France Fitzgerald about concerns they had.
Brian Stack's wife Shelia said her husband “served the State to the best of his ability but the State has let him down”.
She said Mr Adams is “concealing information” and asked him to do “the honourable thing” so she and her family could have closure.
Martin Ferris and Dessie Ellis were named in Mr Adams’ letter to Garda Headquarters.
Mr Stack said he had no information suggesting Mr Ellis knew anything about his father’s murder but said Mr Ferris was questioned by gardai.
He also said Mr Ferris was a “lead operative in the IRA” at the time of the murder.
“Martin Ferris is an individual who wrote scandalous and very hurtful things about my father and then went on Radio Kerry and described the prison management in PortLaoise as Nazis,” Mr Stack said.
“I received confidential information in the last couple of weeks that would suggest to me that the only people who were brutal in Portaloise Prison at the time was the office commanding of the IRA who brutally beat and had beaten the younger IRA prisoners at the time,” he added.
Detectives are conducting a fresh round of interviews with the family of murdered prison officer Brian Stack as they attempt to identify the senior IRA figure who admitted the terror group was behind the 1983 killing.
