Summary

A jury at the Central Criminal Court has been unable to reach a verdict in the trial of Stephen Silver concerning the death of Detective Garda Colm Horkan at Castlerea, County Roscommon on 17 June 2020. Mr Silver accepts that he discharged the detective's own firearm eleven times but denies the charge of murder. The defence argued that Mr Silver should be found guilty of manslaughter on grounds of diminished responsibility, citing evidence that he was suffering from bipolar affective disorder at the time. The jury of seven men and five women deliberated for just under nine hours over three days before reporting they could not reach agreement. Mr Justice Paul McDermott remanded Mr Silver in custody pending a retrial, with the case listed for 9 December at the Central Criminal Court. The judge thanked the jury for their careful consideration of what he described as a deeply difficult and disturbing case. Stephen Silver was acquitted.
