The family of Arlene Arkinson is "deeply frustrated" at delays in concluding an inquest into her death, a coroner's court has heard.
The 15 year old from Castlederg disappeared in 1994 after attending a disco in Bundoran. She had last been seen in the company of convicted child killer Robert Howard, who died in prison last year.
Her body has never been found
The BBC is reporting that at the latest preliminary hearing at Belfast's Coroner's Court this morning a barrister said the family is "becoming more and more upset" at the delays.
He said authorities in Dublin are yet to hand over documents in relation to Garda investigations into the schoolgirl's disappearance.
The court was told representatives for the coroner met officials from the Chief State Solicitor's Office and An Garda Síochána in Dublin to discuss the case in September.
Howard was acquitted of the teenager's murder in 2005 by a jury not told about his conviction for killing another teenager in England.
It’s understood that a further preliminary hearing has been scheduled for later this month.
