The mum of a teenager who was tragically found dead in a ditch after a night out has said she will be "traumatised for the rest of her life".
Matthew McCallan, 15, went missing after attending a country music event in Fintona, Co Tyrone in December.
A search was carried out before his body was found in a ditch by a passer-by two days later. A postmortem found Matthew died of hypothermia.
