Gardaí have issued a new appeal for information, to help them identify a man whose body was found in Galway two years ago.
The man, who is thought to have been between 43 and 48-years of age, was found in a wooded area on the outskirts of the city on 27 September 2014.
Investigations here have yielded no clue as to his identity and checks with police databases internationally have also been fruitless.
In the last 12 months, gardaí commissioned further tests in an effort to ascertain where the man came from. However, isotopic analysis on a tooth gave little in the way of new insights.
A facial reconstruction of the man has been circulated widely but to no avail.
Similarly, checks of missing persons files across the world have not brought detectives any closer to resolving the case and a partial fingerprint taken from the man has not shown up on any database.
He was around 1.83m (6ft) tall, with black hair and a strong build.
His decomposing body was discovered by a local person walking his dog in a wooded area close to Rusheen, just metres from the shoreline. It is thought he had spent a few hours at the scene before his death.
Gardaí believe his remains lay undiscovered for four to six weeks.
He left no trace as to his identity and no indication how he ended up on the western fringes of Galway city.
His clothes - a black leather jacket, jeans and white and blue runners - were most likely purchased in North America. The clothing was manufactured in Jordan and bore the 'Athletech' brand name.
His pockets contained two banknotes, £10 sterling and €5, a gold watch and a single front-door-type key.
Gardaí believe the clothing and bank notes suggest he may have travelled from the US, Canada or the UK in the weeks prior to his death.
He would have travelled from either the Bearna or Salthill direction to reach the place where he died.
While checks of CCTV footage and appeals for information have not led to a breakthrough, detectives are convinced the man had to have some interaction with local residents or business owners in Galway in the hours or days before he died.
Gardaí said the man had a prominent gap between his two top front teeth, which would have been apparent to anybody who had spoken or interacted with him.
Anybody who feels they may be able to assist in the investigation is asked to contact Salthill Garda Station on 091-514720.
