The DPP is to appeal a sentence against a drunk driver who killed a Co Donegal woman and her unborn child.
The late Roisin and her husband Stephen.
Roisin Connolly, from Fanad, was killed when returning to Dublin after spending Christmas in her native county in 2010.
Kevin McArdle of Longfield, Carrickmacross was released from prison last month.
McArdle was three times over the legal alcohol limit and on the wrong side of the road when he crashed into a car on the Carrickmacross by-pass on December 27th.
Two of his friends were killed along with the passenger in the other car 39 year old teach Roisin and her unborn daughter.
Kevin McArdle was jailed for 4 years and disqualified from driving for 12 years at Carrickmacross Circuit Court in 2011.
The DPP is now appealing against the sentence claiming that it is too lenient as the accused had previous driving convictions and showed limited insight into the devastating consequences of his actions.
McArdle’ s lawyers say he knows his actions were wrong, he has served his time and the appeal should fail.
Ms Connolly was in the car with her husband Stephen at the time.
