Silver appeals capital murder conviction for Garda Horkan in Castlerea

On 17 June 2020, Stephen Silver, a 46-year-old motorbike mechanic from Foxford, Co Mayo, shot Detective Garda Colm Horkan, 49, eleven times with Horkan's own gun in Castlerea, Co Roscommon, after a dispute over erratic motorbike driving. Silver was charged with capital murder, pleaded not guilty to capital murder and guilty to manslaughter, and was found guilty of capital murder by a jury at the Central Criminal Court on 15 March 2023 after a first jury in November 2022 was hung. He was sentenced to life imprisonment with a minimum of 40 years on 19 April 2023. Silver appealed his conviction to the Court of Appeal in March 2026, arguing the prosecution's psychiatric evidence contradicted the legal test for insanity, and the court reserved judgment.
