Henry Byrne and John Morley, two officers of the Garda Síochána, the police force of Ireland, were murdered on 7 July 1980 by alleged members of the Irish National Liberation Army (INLA) during a pursuit in the aftermath of a bank robbery near Loughglynn, County Roscommon. The officers' deaths provoked national outrage. Three men were apprehended, convicted and sentenced to death for capital murder. Two of the sentences were later reduced to 40 years imprisonment while the third was overturned.
On 7 July 1980 three armed and masked men raided the Bank of Ireland in Ballaghaderreen, County Roscommon. The group held staff and customers at gunpoint before leaving with IR£35,000. Gardaí of the Irish national police (An Garda Síochána) arrived on the scene but were unarmed and were unable to stop the armed men from escaping in a blue Ford Cortina. The perpetrators were intercepted by a Garda patrol car from Castlerea station with four Gardaí, including Detective John Morley, who was armed with an Uzi machine gun. The two cars collided at Shannon's Cross, Aghaderry, Loughglinn. One of the raiders jumped out of the Cortina and sprayed the patrol car with bullets, killing Garda Henry Byrne.
One man left the Cortina and ran off while his two accomplices – wearing balaclavas – ran in the opposite direction. There was an exchange of shots in which Morley is believed to have wounded one of the men, but he himself was fatally wounded. Both of these men were later apprehended, while a third man - Peter Pringle- was arrested in the city of Galway almost two weeks later. The two other Gardaí - Sergeant Mick O'Malley and Garda Derek O'Kelly - survived the shootout.
John Francis Morley, born 1942 in Knock, County Mayo, was a Garda Síochána detective. Morley was married with two sons, Shane and Gordon and a daughter, Gillian. Morley had also been a noted Gaelic Footballer and was considered one of the best centre backs in the history of Connacht football. He played 112 league and championship games for Mayo between 1961–1974.
