The findings noted in the report confirmed Mid-Ulster UVF leader Robin Jackson's involvement and identified him as an RUC Special Branch agent. According to the report, Jackson had claimed during police interrogations that after the shootings, a senior RUC officer had advised him to "lie low". Although this information was passed on to RUC headquarters, nothing was done about it. In a police statement made following his arrest for possession of the silencer and Luger on 31 May 1976, Jackson maintained that a week before he was taken into custody, two RUC officers had tipped him off about the discovery of his fingerprints on the silencer; he also claimed they had forewarned him: "I should clear as there was a wee job up the country that I would be done for and there was no way out of it for me". Although ballistic testing had linked the Luger (for which the silencer had been specifically made) to the Miami Showband attack, Jackson was never questioned about the killings after his fingerprints had been discovered on the silencer, and the Miami inquiry team were never informed about these developments. Robin Jackson died of cancer on 30 May 1998, aged 49.
