GARDAÍ have appealed for information over the fatal hit-and-run of a young man in Co. Monaghan in 2011.
Fintan Traynor, 20, died when he was struck by a vehicle while walking home along a quiet country road after a night out.
Given the passage of time, gardaí believe someone may come forward due to a change of loyalties in the intervening years.
Crimestoppers have also offered a reward for information on the case.
Audi clue
In the early hours of Sunday, June 26, 2011, Mr Traynor was walking home after a night out in Castleblaney, Co. Monaghan.
At Clontibret, he was struck by a vehicle and fatally injured on the Lemgare Road, a quiet country road little used by passing traffic.
The driver of the vehicle failed to stop and fled the scene.
Eleven years on from Mr Traynor's death, gardaí are once again renewing their appeal for information.
Past appeals have centred on a 1995-2001 Audi A4, which was believed to be the type of vehicle involved in the collision.
The front lower portion of a grille from such a vehicle was found at the scene.
Unfortunately, neither the vehicle nor driver have been located.
'Loyalties, friendships and relationships change'
"We would like to thank the members of the public who have provided assistance to the investigation over the past 11 years, and we are seeking further assistance in locating the vehicle and driver involved," said a garda statement.
"In 11 years loyalties, friendships and relationships change and perhaps someone that felt unable to come forward before is now in a position to provide the investigation team with the vital information that would locate the vehicle and driver.
"Crimestoppers have provided a reward for information in this regard which leads to the recovery of the vehicle and identification and prosecution of the driver."
Anyone with information is urged to contact Monaghan Garda Station at 047 77240, Crimestoppers at 1800 250 025, the Garda Confidential Line 1800 666 111, or any Garda Station.
