Murder accused 'filled with a burning anger' towards gardai, prosecution say

Stephen Silver, a forty-six-year-old motorbike mechanic from Foxford, County Mayo, stands trial at the Central Criminal Court on a charge of murdering Detective Garda Colm Horkan on 17 June 2020 in Castlerea, County Roscommon. Mr Silver has pleaded not guilty to murder but guilty to manslaughter by reason of diminished responsibility. The prosecution closing speech, delivered by James Dwyer SC, contended that Mr Silver was filled with significant anger towards An Garda Síochána and that the encounter with Garda Horkan provided an opportunity to act on that anger. The prosecution argued that Mr Silver's mental state was not impaired in any significant way and that his behaviour that day was purposeful and deliberate. The defence claims Mr Silver was suffering from bipolar affective disorder which diminished his responsibility. A consultant psychiatrist for the prosecution disputed this assessment. The jury will hear closing submissions from the defence before Mr Justice Paul McDermott provides further direction.
