Dundalk Circuit Court has heard how a man who was uninsured and driving at more than 225km/h recorded a video of the high speed he was travelling at in the minutes before a fatal crash.

Three people were killed in the crash which happened on the N1 at Carriccarnan, just south of Junction 20 on the main Dublin to Belfast road on 29 February, 2020.

Keith Lennon, 21, with an address in Forest Park, Dromintee, Co Armagh, was the driver of the car and pleaded guilty of three counts of manslaughter in December last year.

A sentencing hearing took place at Dundalk Circuit Court, sitting in Drogheda today.

He will be sentenced on 12 February.

The court heard how 89-year-old Mary Faxton and her 58-year-old son Kevin Faxton, from Bessbrook in Co Armagh, were travelling along the N1 northbound on the night of the crash.

The court heard that Ms Faxton had suffered from depression and her son often brought her out for a drive at night to "settle her".

They were travelling northbound on the N1 when a red Audi, driven by Lennon, struck their Peugeot 108 from behind.

Bryan Magill, 25, who was a passenger in the car driven by Lennon was also killed.

Two other passengers were in the car at the time of the crash.

Dundalk Circuit Court heard the car was driving at such speed that when the crash happened both cars struck the median barrier before crossing back over the road.

The court heard Lennon had no insurance, his MOT or vehicle roadworthiness certificate had expired and the car had three defective tyres.

Dundalk Circuit Court heard how Lennon left the scene of the crash.

He presented himself at Dundalk Garda Station the following day where he was arrested.

Sergeant Freda McCague of Dundalk Garda Station told the sentencing hearing Lennon was driving the car at 140 miles per hour just before the crash.

She told the court that speed is the equivalent of 225km/h which was 105km above the speed limit.

Sergeant McCague told the court that gardaí retrieved video evidence from the social media app Snapchat, which showed that Lennon had recorded two short videos in the minutes before the crash.

The videos, one which lasted ten seconds and another which lasted four seconds, showed the speedometer in the car at 140mph.

The court heard these videos were forwarded on to a number of people by Lennon while he was driving at high speed.

'The day our world fell apart'

In a victim impact statement written by Mary Faxton's daughter, the Faxton family said that 29 February 2020 "was the day our world fell apart".

The statement also said that words could not express the "grief, pain, loss and heartache" that the family now feel.

A statement read on behalf of Mr Magill's mother spoke of his kindness.

The statement added that Bryan did not know the driver of the car he was in and since the crash they have been hit by a wall of silence.

Lennon's mother told the court that her son understood what he had done and was "so sorry".
