45-year-old Gerard Daly was last seen at his home in Bailieboro in Cavan on the 26th of June 2011.
Gerard was formally from Knockmore Grove in Tallagh, Dublin and was well known to dog enthusiasts.
A missing persons report was filed just three days after he disappeared but there was no sign of him until two days ago – a full three years later – when his remains turned up in a bog in Meath.
The find was made during excavation work at Oristown Bog near Kells on Thursday.
A burnt out shell of a car was also recovered at the scene and it s understood the car was reported stolen in the Kells area in 2003.
A man in his 50 s was arrested in March last year in connection with this investigation but was released without charge the following day.
A technical and forensic examination at the scene has concluded and the investigation continues this evening.
