Joe Tiernan maintained that the man who shot and killed Hanna was Robin Jackson who then assumed command of the Mid-Ulster UVF . Sean McPhilemy 's '' The Committee : Political Assassination in Northern Ireland '' claims the Provisional IRA had initially been blamed for his killing . Hanna was allegedly shot after he had refused to participate in the UVF 's planned Miami Showband attack which Jackson had personally organised and would help to carry out on 31 July . His refusal stemmed from his purported remorse at the part he had played in the killing of " all those children in Dublin " , which was a referral to his having instructed David Alexander Mulholland to drive and park the first car bomb which had detonated in Parnell Street , killing two infant girls and eight other people . By the time the Miami Showband ambush was in its planning stages , Hanna had already begun to distance himself from the UVF
