Today marks the 39th anniversary of the deaths of Longford native Private Patrick Kelly and Garda recruit Gary Sheehan in Leitrim in 1983.
The two men were shot dead by the IRA as they took part in a search operation for kidnapped Quinnsworth CEO Don Tidey.
Private Kelly who was originally from Ballinamuck in Longford was living in Moate at the time of the incident, and was stationed at Custume Barracks in Athlone.
Recruit Garda Gary Sheehan who was from Carrickmacross in Monaghan was one of a number of recruits undergoing training at Templemore, who were sent to supplement the search over a wide area of Derrada Woods outside Ballinamore.
The Supermarket CEO Don Tidey was rescued safely at the scene, but no one has ever been charged in relations to the deaths of Paddy Kelly or Gary Sheehan.
A garda medal ceremony was held in Dublin last year with 14 Scott medals presented to Garda members resulting from their actions in Derrada.
A Gold Scott medal was awarded posthumously to Garda Sheehan.
