A search is under way in Co Donegal as part of the investigation into the disappearance of a 46-year-old woman ten years ago.
The land search and excavation in Milford is part of the ongoing investigation into the disappearance of Dr Deirdre O'Flaherty from Co Tyrone, who was reported missing on 11 January 2009.
Dr O'Flaherty, also known by her maiden name of Deirdre Donnelly, disappeared while staying at a holiday home with her family.
Her car was found at Kinnego Beach.
Gardaí say they are liaising closely with the missing woman's family and a garda family liaison officer has been appointed.
The search is being carried out by members of the Donegal Divisional Search Team and Garda Technical Bureau, along with private contractors, and it is expected to last up to five days.
Gardaí say the search is part of an investigation into the disappearance of a woman on 11 January 2009 at Moville.
In January 2012, three years after she disappeared, the High Court in Belfast ruled it was satisfied that Dr O'Flaherty had died.
The judge used new legislation for the first time - the Presumption of Death Act - in Northern Ireland to declare he was satisfied that Dr O'Flaherty had drowned after going into the sea in Co Donegal.
The court was told she had suffered from depression.
