Human remains found as part of the Tina Satchwell murder investigation are being sent for DNA analysis.
The remains were found under the floor of a house on Grattan Street in Youghal on Wednesday evening.
The Coroner was notified and the Assistant State Pathologist, Dr Margot Bolster, attended the scene on Thursday morning.
The human remains have been removed to Cork University Hospital, where they will be subject to further examination including DNA analysis.
Gardaí have said they are continuing to investigate "all the circumstances" surrounding her murder.
Ms Satchwell was reported as missing from her home on Grattan Street, Youghal in Co Cork in March 2017.
A technical examination at a house in Youghal is continuing.
A search at a second location, between Youghal and Killeagh, has been completed.
A man aged in his 50s was arrested earlier today on suspicion of murder, and is currently detained under Section 4 Criminal Justice Act at a Garda station in Co Cork.
The family of Ms Satchwell continues to be updated on the progress of this investigation by an appointed Family Liaison Officer.
Superintendent Adrian Gamble made a renewed appeal for information.
