It is exactly two years to the day since Garda Adrian Donohoe was shot dead.
The detective was 41 years old when he was shot dead while trying to stop a robbery at his local credit union in Lordship, Co Louth.
The married father of two was the first garda officer to be shot dead in the line of duty since 1996.
Nobody has been arrested or charged in relation to his death.
Earlier today, Garda Commissioner Nóirín O'Sullivan attended a memorial Mass for Garda Donohoe at St Joseph's Church in Dundalk.
She said very significant progress had been made in the investigation into the murder, and that the force needed to get things "100% right" before those responsible could be brought to justice.
Garda Donohoe's widow Caroline, their two children, colleagues and the community of Bellurgan attended today's memorial Mass.
