Today (Monday) marks the 18th anniversary of the murder of 21-year-old Paul Quinn in Co Monaghan.
The young man was murdered in the Tullyvanus area on Saturday, October 20th, 2007, after being lured to a shed by a number of men.
On the anniversary of his murder, local Gardai say the investigation into Paul’s killing is ongoing.
During the course of the investigation, 23 people have been arrested which includes 14 people who were arrested by Gardai and 9 who were arrested by the Police Service of Northern Ireland.
In March of 2020, a thematic review of this investigation was completed by the Garda Serious Crime Review team.
Gardaí say they continue to work with their colleagues in the Police Service of Northern Ireland in efforts to solve this crime.
Gardai say the solving of this murder is of the utmost priority for An Garda Síochána and any information received will be treated with absolute confidentiality.
Gardaí believe that there are still people with information in the community who have yet to come forward.

Superintendent Ronan Carey said: "We firmly believe that the answers to this murder or the evidence that we require to progress this investigation lies within the community.
”He said relationships change or the nature of them, and that people may be in a position now to provide answers to us or come forward to us and give us information that they may not have been previously in a position to do so.
”We want to provide the answers, and we want to provide justice to Paul, to his mother, Breege, and his father, Stephen.”
Gardai says regular contact with the Quinn family continues and they are updated regularly on any developments in the case.
Breege Quinn, Paul’s mother said: "The Gardaí are still investigating the murder. Please go and give us justice. It's no easier today than it was that evening that he died.”
