Coniston massacre
Brooks was killed on or about 7 August 1928, and his body was partly buried in a rabbit hole. No eyewitnesses to the actual murder were ever identified, and there are conflicting accounts of the discovery of the body and subsequent events.
Kevin O'Higgins
None of the three assassins was ever apprehended or charged, but Coughlan, a member of Fianna Fáil as well as the IRA, was killed in strange circumstances in Dublin, in 1928, by a police undercover agent whom he was attempting to murder. The other two (Doyle and Gannon) benefited from the amnesty to IRA members issued by Éamon de Valera, upon his assumption of power in 1932. Gannon, who died in 1965, joined the Communist Party of Ireland and played a central role in organising Irish volunteers for the Spanish Civil War. Yet in party publications his part in assassinating O'Higgins is downplayed.Doyle remained a prominent IRA militant and took part in various acts in the early 1940s. He lived to an old age, dying in 1980, and continued to take pride in having killed O'Higgins.
