At the 1922 general election, he was elected to the Third Dáil as a pro-Treaty Sinn Féin Teachta Dála (TD) for the same constituency. He received 4,374 first-preference votes (7.9%).[5] Shortly afterwards, the Irish Civil War broke out between the pro-Treaty faction, who were in favour of setting up the Irish Free State and the anti-Treaty faction, who would not accept the abolition of the Irish Republic.[6]
On 7 December 1922, Hales was killed by anti-Treaty IRA men as he left the Dáil. Another TD, Pádraic Ó Máille, was also shot and badly wounded in the incident. His killing was in reprisal for the Free State's execution of anti-treaty prisoners. In revenge for Hales' killing, four republican leaders (Joe McKelvey, Rory O'Connor, Liam Mellows and Richard Barrett) were executed the following day, 8 December 1922.[7][8]
According to information passed on to playwright Ulick O'Connor, an anti-Treaty IRA volunteer named Owen Donnelly of Glasnevin was responsible for the killing of Hales. Seán Caffrey, an anti-treaty intelligence officer, told O'Connor that Donnelly had not been ordered to shoot Hales specifically but was following the general order issued by Liam Lynch to shoot TDs or senators if they could.[9]
A commemorative statue of Hayes was unveiled at Bank Place in Bandon, in 1930.[10]
