Cases
latest first- Brady's perverting the course of justice sentence increased in Louth Perverting the course of justice · Co. Louth
Aaron Brady, 35, from Crossmaglen, Co Armagh, was convicted in August 2020 of murdering Detective Garda Adrian Donohoe during a robbery at Lordship Credit Union, Bellurgan, Co Louth, on 25 January 2013, and sentenced to life imprisonment with a 40-year minimum. During his 2020 murder trial, Brady recorded a Garda interview with witness Ronan Flynn and posted it on social media, and conspired with Dean Byrne, 33, from Dublin, to persuade prosecution witness Daniel Cahill not to give evidence. Brady pleaded guilty to perverting the course of justice at the Special Criminal Court in April 2024 and was sentenced to three years in July 2024, while Byrne was convicted of the conspiracy and sentenced to two years. In July 2026, the Court of Appeal increased Brady's sentence to five years, finding the original three-year term too lenient and failing to give sufficient weight to general deterrence.
Sentenced, 29 Jul 2024Convicted, accused, suspect · 24 reports - Supreme Court in Dublin to hear perverting course of justice appeal Conspiracy to pervert the course of justice · Co. Dublin
Dean Byrne, 33, of Cabra Park, Phibsborough, Dublin, was convicted in June 2024 of conspiring with Aaron Brady, 35, to persuade prosecution witness Daniel Cahill not to give evidence at Brady's trial for the 2013 murder of Detective Garda Adrian Donohoe at Lordship Credit Union, Bellurgan, Co Louth. The alleged conspiracy took place in Mountjoy Prison between 8 April and 22 June 2020, during which Byrne is said to have shared photographs of Cahill's statement with relatives and recruited family members to pressure the witness. Brady was convicted of murder in August 2020 and sentenced to life with a 40-year minimum, while Byrne received a two-year sentence in July 2024. The Court of Appeal dismissed Byrne's appeal in December 2025, and the Supreme Court will now hear his challenge on the legal question of whether it can ever be lawful to persuade a witness not to give evidence.
