No files in relation to the arrest and conviction of double killer Malcolm Macarthur have been cleared for release in the tranche of 30-year-old documents.
Despite the "Gubu" events of 1982, as Charles Haughey then called it, any papers concerning his sensational arrest at a home owned by the then attorney general are still considered live.
Macarthur, 67, is a lifer and will be until his death, living out his days on licence and under the close supervision of the authorities.
The Taoiseach's office revealed that it does not have any files in relation to Bridie Gargan, the nurse killed by Macarthur as she sunbathed in Phoenix Park, or Donal Dunne, a farmer from Edenderry, Co Offaly, who was selling a shotgun which days later Macarthur used to kill him.
Nor have any files been handed to the department on the whole Gubu affair, an acronym based on Mr Haughey's famous description of Macarthur's arrest: "A bizarre happening, an unprecedented situation, a grotesque situation, an almost unbelievable mischance."
The socialite was staying at an apartment in Pilot View, Dalkey, owned by his friend, the then attorney general Patrick Connolly, when detained by gardai for the two murders.
The attorney general thought little of it and left for a holiday in the US, only to be ordered back to Dublin by Mr Haughey to tender his resignation.
The scandal and the frenzy over the killings and Macarthur's arrest prompted Mr Haughey's observation.
He confessed to killing Ms Gargan while trying to rob her car. He was mentally unwell and wanted a vehicle to carry out a bank robbery after splashing an inheritance in a six-week splurge in the Canaries with partner Brenda Little and son Colm Malcolm.
Macarthur was jailed for life in January 1983 for murdering Ms Gargan but a prosecution for Mr Dunne's murder was not pursued. In a statement the Department of Justice confirmed that files in relation to the Macarthur case are under its control.
