Friends and family of Detective Garda Adrian Donohoe will gather tonight for a candlelit vigil at the spot where he was killed in the line of duty.
It's been exactly one year since the 41-year-old father of two was gunned down during a robbery at Lordship Credit Union in Co. Louth.
Adrian Donohue was shot once in the head at close range while providing an armed escort for staff who were carrying cash for lodgement.
The horror of his murder was felt right across the country.
In the immediate aftermath, the Taoiseach described it as an "outrageous act of cold-blooded violence".
And when Enda Kenny rose to his feet in the Dáil a few days later, the nation hung onto his every word as he promised no stone would be left unturned in the pursuit of Adrian's killers.
So far, the investigation team has taken over 2,100 statements, gathered 400,000 hours of CCTV footage and collected over 1,200 exhibits.
Despite that, nobody has been charged in relation to Adrian's murder but Garda Commissioner Martin Callinan says they have them in their sights.
Gardai suspect the killers are part of a dangerous gang based in Armagh and Commissioner Callinan believes they're being protected.
He understands people's fears in coming forward but assures them they'll be safe if they choose to do so.
One year on and the hurt felt by Adrian's wife Caroline, their two children, family, friends and colleagues is still very raw.
Tonight, he'll be remembered at a candlelit vigil where he was gunned down before a walk by candlelight to his local GAA grounds.
