Gardaí have narrowed down their hunt for a driver following a fatal hit-and-run in Donegal.
A man in his early 30s was found in a serious condition on the roadside on the outskirts of Letterkenny at Windyhall around 4am yesterday.
He was taken rushed to nearby Letterkenny University Hospital, but was pronounced dead a short time later.
The deceased has been named locally as Jason Haughey, who was originally from Letterkenny.
It has now been revealed that Garda forensic investigators have recovered car parts from the scene.
It is understood they are satisfied they know the make, model and colour of the car.
Although Mr Haughey was found at 4am by a road user, the accident could have happened much earlier.
Gardaí are appealing for anybody who drove along the road between 1am and 4am and who may have dashcam footage to contact them.
A Garda spokesman said: "At approximately 4am, the body of a man was discovered by a road user along the roadway at Windyhall, Letterkenny, Co Donegal."
Following an examination of the area, it was identified that the male was hit by a vehicle that failed to remain at the scene.
Forensic collision investigators were at the scene, which was preserved for a full technical examination.
Anyone with information is asked to contact Letterkenny garda station on 074 9167100, the Garda Confidential Line on 1800 666 111, or any Garda station. Officers are also calling door-to-door as part of the investigation, while local CCTV footage is also being harvested.
Gardaí have not yet released details of the make or model of the car that they think was involved in the incident.
Members of Mr Haughey's family have been informed of his death.
Mr Haughey, who was well known in Letterkenny, was not married.
His remains are being held at Letterkenny University Hospital where a post-mortem examination will take place.
Members of the Garda forensics squad remained at the scene all day yesterday.
A children's scooter could be seen close to parts from what is believed to be the car involved in the hit-and-run.
However, it is not known whether the scooter will form any part of the Garda investigation.
