Jury sworn in for trial of man accused of Roscommon murder of Garda Colm Horkan

Stephen Silver (46) pleaded not guilty to murder but guilty to manslaughter for reason of diminished responsibility

A jury has been sworn in at the Central Criminal Court for the trial of a man who denies murder but admits to the manslaughter of a detective garda in Co Roscommon in 2020.

On Monday, mechanic Stephen Silver appeared in the court pleading not guilty to the murder of Detective Garda Colm Horkan (49) during the course of his duties in Castlerea, Co Roscommon on June 17th, 2020.

However, when the murder charge was read by the registrar to Mr Silver (46) of Aughavard, Foxford, Co Mayo, he replied “not guilty” but added “guilty to manslaughter for reason of diminished responsibility”.

Mr Justice Paul McDermott told the jury panel before their selection that they should not serve as jurors if any of their immediate family were members of An Garda Síochána.


He also told the jury of seven men and five women that the case was one of murder and that the trial would last up to seven weeks. He then adjourned the matter to Friday October 7th.

If found guilty of the murder of Detective Garda Horkan, Mr Silver faces a mandatory sentence of 40 years in jail.
