Gardaí investigating the disappearance and murder of Elizabeth Clarke have finished an extensive search of a property and its adjoining garden in Co Meath.
The results of the three-and-a-half day search are not being released for operational reasons, gardaí have said.
There was a large garda presence at the site of this search operation across the weekend.
Members of the Meath Serious Crime Hub, the Meath Divisional Search Unit and the Garda National Technical Bureau could be seen coming and going from the property since Friday.
Gardaí said they worked through very difficult conditions to intrusively search the interior of the property.
Considerable excavation works were also carried out in the garden at the rear of the property with the use of a mini-digger.
Gardaí deployed their own drone to take pictures of and analyse the topography of the back garden.
Four industrial-sized skips were filled during the course of the search.
A forensic archaeologist remained on standby in case their expertise was required by investigating gardaí but it is understood they were not called upon.
Ms Clarke previously lived in both Portrane in north county Dublin and in Bettystown, Co Meath, with her family.
However, she was living in Navan at the time of her disappearance in 2013, when she was 24 years old.
Ms Clarke was officially reported missing by her family just over a year later in January 2015 and an extensive investigation into her disappearance was launched.
However, despite this, there have still been no sightings of the mother-of-two in over ten years.
Gardaí have said they have updated Ms Clarke's family on today's developments.
They also continue to appeal to anyone with information in relation to the disappearance and murder of Ms Clarke to come forward.
In a statement this evening confirming that the search had been stood down, a garda spokesperson said: "Do not assume that An Garda Síochána either know that information and/or that it has limited value. Let the investigation team make that assessment.
"Given the time frame of this investigation, gardaí are reminding the public that if they have any information in relation to the disappearance and murder of Elizabeth and for some reason held back on information they may have had, to come forward now.
"An Garda Síochána wish to reassure them that they will be treated sensitively.
"The investigation team can be contacted at Navan Garda Station at 046 9036100, through your local garda station or the garda confidential telephone line 1800 666 111.
"Investigations are ongoing."
