A motorist whose high-powered Range Rover hit and killed a man on a country road near Glasgow has been sentenced to 18 months detention.
Ross McChrystal, 20, was driving at more than twice the 30mph speed limit when he hit Edward Devlin on the A891 Campsie Road, Lennoxtown, in June 2009.
He admitted causing the 40-year-old pedestrian's death by careless driving.
At the High Court in Glasgow temporary judge Sean Murphy QC said the only possible sentence was a custodial one.
The court heard how the incident happened at about 0230 BST on 22 June as Mr Devlin and his partner Theresa Sinclair walked home in Lennoxtown after a night at a friend's house.
McChrystal, from Kirkintilloch, was driving home after dropping off a female friend when he rounded a bend and saw Mr Devlin walking along the middle of the carriageway.
When he applied the brakes, his high-powered Range Rover moved across the road and struck Mr Devlin.
The victim, who was blind in one eye, was then thrown further along the road.
McChrystal got out of his car, attempted CPR and called for an ambulance.
A passing off-duty nurse also tried to help but could not find a pulse and Mr Devlin was pronounced dead at the scene by paramedics.
Crash investigators later concluded that McChrystal, who has previous convictions for driving offences, was likely driving at 71mph before the crash.
Sentencing him temporary, judge Sean Murphy QC described McChrystal as an "upstanding young man who has led an exemplary life".
However, judge Murphy added: "You displayed a high degree of carelessness in a vehicle relatively new to you.
"I accept the deceased contributed to the accident by placing himself in the middle of the roadway.
"Your error has caused the death of Mr Devlin and the only possible sentence is a custodial one."
