A renewed appeal for information has been issued in relation to the murder of Sandra Collins, ahead of the 20th anniversary of her disappearance tomorrow.
Ms Collins was last seen on the night of Monday 4 December 2000, at around 11pm at the Country Kitchen premises on George's Street in Killala, Co Mayo.
She was 28 at the time, and the investigation into her disappearance still remains active.
Gardaí are asking anyone who may have any piece of information that they feel is relevant to the investigation to get in touch.
Chief Superintendent Tony Healy, of the Mayo Garda Division, said they have not stopped searching for Sandra, and appealed for people to contact them.
"Perhaps you have information you thought was insignificant at the time, or it could be that after 20 years have passed your circumstances have now changed.
"It could be that you were afraid or anxious to make contact with An Garda Síochána at the time. We are asking you now to make contact with us in whatever way you can," he said.

In a statement this afternoon Sandra's brother, Patrick Collins, urged anyone with information to come forward.
"Our parents, Eleanor and Joe have gone to their graves far too soon due to emotional stress and the anguish they carried over our beloved Sandra," he said.
He added: "Nothing, but nothing, can be as bad as not having Sandra's remains back. I have dreamt of a small family funeral for Sandra.
"I wake up with tears running down my face and yet realise it will be one of the greatest days of my life. I can visit her grave. We will have her home. We can talk to her at her graveside. We can lay flowers. We can grieve. Please give us our sister back", he said.
Chief Supt Healy added that it was possible information the public brings forward could help give the family some closure as Christmas approaches.
Gardaí are asking with information to contact Ballina Garda Station on 096-20560, the Garda Confidential Line on 1800 666 111, or any garda station.
They have said that anyone who comes forward will be treated with confidentiality, compassion, and sensitivity.
