Seán McCárthaigh
An individual is facing a criminal prosecution over the death of a Dáil usher cycling home from work in Dublin two years ago, an inquest has heard.
Derek Doyle (58), a married father of one from Clonsilla, Dublin, was killed in a crash involving a lorry and his bicycle in Castleknock on December 19th 2024.
The fatal incident occurred at the junction of College Road and Castleknock Village at approximately 4.30pm.
The opening of the inquest into Doyle’s death at Dublin District Coroner’s Court on Tuesday, July 28th, heard a postmortem showed the deceased had died as a result of cranial cerebral trauma.
Doyle’s brother-in-law, David Dillon, gave evidence of formally identifying the deceased’s body to gardaí at the mortuary in Connolly Hospital Blanchardstown on December 23rd 2024.
The coroner, Cróna Gallagher, informed the hearing that DNA analysis had also been used to confirm Doyle’s identity due to the nature of the injuries he sustained in the collision.
Detective Inspector Liam Donohoe applied for an adjournment of the inquest under Section 25 (2) of the Coroners Act on the basis that criminal proceedings in the case have already been initiated.
Offering her condolences to Doyle’s family, Dr Gallagher granted the application and adjourned the hearing without fixing any future date for any resumption of the inquest to allow for the conclusion of related criminal proceedings.
Doyle was a former member of the Defence Forces and had worked on the Government jet as part of the Ministerial Air Transport Service while attached to the Air Corps.
He is survived by his wife, Tania Doyle, an independent member of Fingal County Council and his daughter, Hazel.
The deceased had been physically attacked earlier in 2024 while helping his wife to put up posters during that year’s local election campaign.
Following her husband’s death, Doyle called for the junction at the location of the fatal incident to be made safer for cyclists.
She also claimed that the route through Castleknock village is unsuitable for heavy goods vehicles.
However, Fingal County Council said it concluded the junction was safe for all road users after conducting a standard collision report following Doyle’s death.
The local authority said it had no plans to make changes to the junction or to restrict heavy goods vehicles from the route.
The coroner’s court also heard about the death of a teenager as a result of severe head injuries he sustained when his bicycle was struck by a car in west Dublin 12 months ago.
Luke Byrne (19) from Ashley Hall, St Edmund’s, Lucan died at Beaumont Hospital in Dublin on August 4, 2025 from injuries suffered in a collision on the R113, Fonthill Road South in Clondalkin eight days earlier.
The fatal incident occurred around 11.40pm on July 27, 2025.
The deceased’s mother, Martina McGarry, gave evidence of formally identifying her “loving son” to gardaí.
McGarry said her son had originally been brought to Tallaght University Hospital by ambulance following the crash before he was transferred to Beaumont Hospital due to the seriousness of his injuries.
She also recounted how Luke was her only child.
The coroner said the result of a postmortem showed he had died as a result of cranial cerebral trauma due to a road traffic collision.
Inspector Michael Egan applied for an adjournment of the inquest on the basis that criminal proceedings are being considered in the case.
Egan said an existing criminal matter is currently before the courts, but further charges are being considered.
Gallagher consented to an application for a six-month adjournment after confirming that nobody had been charged in relation to Byrne’s death so far.
She listed the case for further mention on February 11th 2027.
Offering her condolences to McGarry, the coroner also noted that the hearing was taking place close to her son’s first anniversary.
