Another persistent allegation is the direct involvement of Mid-Ulster UVF leader Robin Jackson, a native of Donaghmore, County Down, one and a half miles away from Buskhill. He was one of the men taken in by the RUC in August 1975 and questioned as a suspect in the killings, but was released without charge. The independent panel of inquiry commissioned by the Pat Finucane Centre concluded that there was "credible evidence that the principal perpetrator the Miami Showband attack was a man who was not prosecuted – alleged RUC Special Branch agent Robin Jackson". The same panel revealed that about six weeks before the attack, Thomas Crozier, Jackson, and the latter's brother-in-law Samuel Fulton Neill, were arrested for the possession of four shotguns. Neill's car was one of those allegedly used in the Buskhill attack. He was later shot dead in Portadown on 25 January 1976, allegedly by Jackson for having informed the RUC about Thomas Crozier's participation in the attack. The panel stated that it was unclear why Crozier, Jackson, and Neill were not in police custody at the time the Miami Showband killings took place. Martin Dillon maintained in "The Dirty War" that the Miami Showband attack was planned weeks before at a house in Portadown, and the person in charge of the overall operation was a former UDR man, whom Dillon referred to for legal reasons as "Mr. A". Dillon also opined in "God and the Gun: The Church and Irish Terrorism" that the dead bombers, Harris Boyle and Wesley Somerville, had actually led the UVF gang at Buskhill. Journalists Kevin Dowling and Liam Collins in the "Irish Independent" however, suggested in their respective articles that Jackson had been the leader of the unit.
