Gardai have issued a renewed appeal for assistance in identifying a man found dead in Galway city last year.

The body of a man was found in Rusheen Woods, near Bearna, on September 27 last. While the death is not being treated as suspicious, gardai have been unable to find out who he was.

In an effort to solve the mystery officers contacted experts at Dundee University, where a facial reconstruction image was created.

The man is described as being between 30 and 40 years of age. He had a broad, strong build and was approximately six-foot tall with black hair.

He was wearing a gold bracelet watch (a Caravelle by Bulova) and had a single key in his pocket, along with a small amount of euro and sterling.

He was wearing a black leather jacket, blue jeans and white-and-blue Athletech runners. He also had a black belt with metal flower-design studs across its length, with a silver-colour buckle. The remains were discovered by a man walking his dog. Detective Sergeant Paudie O'Shea said despite an extensive appeal for information they still know very little about the deceased.

"This man had no identification and had nothing on him apart from a small amount of currency and a key," he said.

Gardai believe that the man's remains may have lain in the Rusheen Woods for between six to eight weeks prior to their discovery.

However, because of the warm weather at the time the time scale may be shorter.

"If we take it that it was eight weeks that would have been at the end of the Galway races," said Detective Sergeant O'Shea.

"He may have come to Galway for that, but we just don't know. However, we do believe he had somewhere to stay in the country. He had a single key on him. Locksmiths in Galway told us this is a Yale lock at eye level," he added.

Gardai have renewed their appeal to hotels, bed and breakfasts and landlords to contact them if they have any information on the man.

Officers sent a DNA sample and a fingerprint from the deceased to Interpol, but no match was found.
