Gardaí in Co Meath have identified the remains found in a field in Clonee yesterday and today.
The body is believed to be of a 37-year-old man from the Blanchardstown area of Dublin.
His name has not yet been released.
The discovery of an arm was made around 4.30pm yesterday by a person out walking.
The remains found today were removed to Connolly Hospital, Blanchardstown, where Deputy State Pathologist, Dr Kalhid Jabber is currently carrying out a Post-Mortem on these remains.
Officers were concentrating in fields and woods around a stream at The Mayne which marks the Dublin-Meath border when they found further remains this afternoon.
Fingerprints were taken from the limb found yesterday and Garda databases were checked for any matches.
DNA samples were compared against records of people missing.
Gardaí at Ashbourne are appealing for anyone with any information to contact them.
