Ten years on from a hit and run in Co Monaghan in which a 20-year-old man died, gardaí are renewing their appeal for information.

Fintan Traynor was walking home after a night out in Castleblayney in the early hours of 26 June 2011 when he was struck by a car at Lemgare, Clontribret.

The driver of the car failed to stop and left the scene.

On the 10th anniversary of his death gardaí are once again asking for information and say they believe an Audi A4 – 1996 to 2001 model – was involved in the incident.

They say the front lower portion of the grille was recovered by gardaí at the scene at the time of the hit-and-run.

Detectives have followed 400 leads in the past ten years, however the car and driver have yet to be located.

Inspector Adrian Durcan of Monaghan Garda Station has appealed to the public for information.

"With the passage of time now perhaps someone may feel more comfortable coming forward with information in relation to this matter," he said.

"In 10 years, loyalties, friendships and relationships change and perhaps now you are in a position to provide the investigation team with the vital information that would locate the vehicle and driver," he added.

Gardaí say anyone with information can contact them in the anonymously if they wish to do so.

A reward for information which leads to the recovery of the vehicle and identification of the driver is available through Crimestoppers.

"To the person who was involved in this incident, I have no doubt this is something that has weighed heavily on your mind for the past 10 years. I would encourage you to do the right thing and make contact with us in Monaghan Garda Station said Inspector Durcan."

The Traynor family are always appealing for information which could provide them with some answers as to what happened.

"Although such a time has passed we still have an overwhelming sense of loss given we do not know what happened to Fintan on that fateful morning," said Bridie Traynor, Fintan's mother.

"We appeal to anyone with any information, no matter how insignificant it may seem, about someone or other people's behaviour around that time of June 26, 2011 to come forward and assist the Gardaí with their inquiries," she said.

"Our lives were irrevocably changed that morning and although we know that we will never have Fintan back we as a grieving family deserve to understand what happened," she added.

Anyone with information is asked to contact Monaghan Garda Station at 047 77200, Crimestoppers at 1800 25 00 25 or any Garda Station.

An appeal will also be broadcast on Crimecall on Monday on RTÉ 1 at 9.35pm.
