due to appear in court via video link again on 20 November. 27 November – Silver appeared at Castlerea District Court where he was charged with the capital murder of Detective Garda Colm Horkan, and was remanded in custody to the Midlands Prison in Portlaoise to appear via video link before Harristown District Court on 4 December. Trial On 19 February 2021, Silver was sent forward for trial to the Central Criminal Court charged with the murder of Horkan. On 23 March 2021, it was announced that Silver would go on trial at the Central Criminal Court on 15 June 2022. In April 2022, it was announced that the trial was delayed until October 2022. Silver went on trial on 7 October 2022 and pleaded not guilty to the murder of Horkan acting in the course of his duty, but guilty to manslaughter on the basis of diminished responsibility. Silver told the Central Criminal Court that he shot Horkan because of "all that was going on with the police in the world", claiming he had been attacked by Horkan at first and was also heard to mention "black lives matter" in the immediate aftermath of the shooting. The court heard Silver had been diagnosed with bipolar disorder and had a history of mental illness and hospital admissions going back nearly 20 years. The defence argued that he was suffering from a relapse of his mental disorder at the time of the shooting. The prosecution case was that Silver was filled with anger towards Gardaí and there was no evidence that his mental disorder had caused him to act in the way he did. On 17 November 2022, the jury at the Central Criminal Court failed to reach a verdict in the trial of Silver.
