An employee at Parliament Buildings has been jailed after pleading guilty to causing death by dangerous driving.
Steven Warnock, 25, from Main Street, Portavogie, was driving at speed on the wrong side of the Bog Road outside Portavogie when his car hit another vehicle on 11 April 2009.
The driver of the car, John Cully, 21, was killed instantly. A passenger in Mr Warnock's car was grievously injured.
Warnock will serve half of the 16-month sentence.
Crown Court Judge David Smith told the court that Warnock, who had entered an early guilty plea and spent several weeks in hospital himself, had shown "genuine remorse" and that the former head boy of Glastry College was a hard working father of one.
The district judge also told Downpatrick Crown Court that this was a distressing, tragic case, and that the victim, John Cully, was also of good character.
Warnock sobbed as he was led away in handcuffs from the dock, with friends and family of both the victim and the defendant watching.
