A 19-year-old man has been sentenced to 14 months in jail for careless driving causing the death of a 16-year old girl and for careless driving causing serious harm to two friends.
Edward O'Shea of Magnh, Fenor, in Waterford was the driver of a car which went out of control and crashed near Tranmore in October 2016.
Katie Murphy, 16, died when O'Shea lost control of the car and crashed near Tramore.
Her friends, Jessica Flynn and Joseph Walsh, were seriously injured.
Ms Murphy was described by her brother as someone who injected humour and kindness into the lives of those who knew her.

Her father described her as "so loving" and said she was loved by all her friends family and was a "joy to be around".
Speaking to RTÉ News her mother Vivienne said their house was so quiet following Katie's death.
On 5 October 2016, Katie was a back-seat passenger in a car being driven by O'Shea.
He was 17 and worked with his father as an apprentice mechanic at the O'Shea's garage.
He was on a learner permit and was not accompanied by a qualified driver.
His car was a high-powered, modified, Japanese import owned by the O'Shea garage. It was alleged he was driving at an excessive speed.
O'Shea was convicted by a jury last month of careless driving causing Katie's death and causing serious injury to his two other passengers.
Judge Eugene O'Kelly sentenced him to 14 months in jail, adding that it was blatantly irresponsible of the O'Shea garage business to facilitate his driving of the car.
