An investigation into the disappearance of 43-year-old Mark Duffy, who was last seen on 3 October 2022 in Navan, has been upgraded to a murder investigation.
In the weeks before his disappearance, Mr Duffy had been homeless and living in a tent in Navan town.
On the day he was last seen, he was at the Post Office at the Johnstown Shopping Centre in Navan at 10.50am.
He was later seen at about 2.45pm on CCTV on the Commons Road, walking into McDermotts Villas Housing Estate.
This was the last confirmed sighting of him.
He was later reported missing 10 days later by a family member who was concerned that she had not heard from him.
Garda investigations established that there had been no sightings of Mr Duffy since 3 October, that his phone had not been used and he had not left the country.
Searches in Navan and the River Boyne were carried out, but there have been no sightings and no evidence of his whereabouts.
Today, An Garda Síochána said that it has maintained an active investigation into his disappearance, led by a Senior Investigating Officer in Navan.
They said that based on the available information, the missing person investigation has now been reclassified as a murder investigation.
Mr Duffy's family was updated by gardaí and a family liaison officer about the development today.
Gardaí are continuing to appeal to anyone with information about the disappearance and murder of Mark Duffy to contact them.
He is described as being 5'8 in height, of broad build with brown hair and blue eyes. At the time he went missing, he walked with a noticeable limp.
He was wearing dark clothing, with a cream hoodie underneath. The hood was outside his jacket when he was last seen.
They have particularly appealed to people who were in the area of the Commons Road on the afternoon of 3 October 2022.
Anyone with information who can assist gardaí are asked to contact Navan Garda Station on 046 9079930, the Garda Confidential Line on 1800 666 111, or any garda station.
