A search operation in north Co Dublin in connection with the disappearance and murder of William Maughan and Anastasija Varslavane has been stood down by gardaí.
The search of an area of bog land began on Friday. However, gardaí said nothing of evidential value discovered during their searches.
Gardaí said they have updated the family about the developments.
Mr Maughan and Ms Varslavane were first reported missing in 2015 and the search launched last week forms part of a long-running investigation that was upgraded to a murder case in 2016.
The couple, who had been together since 2014, had lived in a caravan in Gormanston, Co Meath, about a ten-minute drive from the search site.
They were planning to move in with Mr Maughan’s parents in Tallaght at the time of their disappearance.
When Mr Maughan’s mother, Helen turned up to collect her son and Ms Varslavane in Gormanston on Tuesday 14 April 2015 and bring them to Tallaght and they were not there, she became worried and reported them missing.
An extensive missing persons investigation was subsequently launched and then, in September 2016, the case was upgraded to a murder investigation.
To date, seven people have been arrested in connection with the couple’s disappearance.
However, no one has faced criminal charges in relation to the case.
Gardaí have said that they hope with the passage of time, people will now be in a position to come forward with new information.
They are asking anyone with any information, no matter how small or insignificant they might believe it to be, to contact Ashbourne Garda Station on 01 801 0600, the Garda Confidential Line at 1800 666 111 or any garda station.
A garda spokesperson has said any information will be treated with the strictest confidence and investigations remain ongoing.
