A judge has again ordered a psychiatric assessment on a Donegal man charged with the murders of his parents.

Julian Cuddihy, 42, appeared before a special sitting of Letterkenny District Court this morning.

He had been remanded in custody to Castlerea Prison after appearing at Ballyshannon District Court last Friday night.

At that sitting Judge Kevin Kilrane asked to have him psychologically assessed as soon as was practicably possible.

However, Mr Cuddihy's solicitor Ray Lannon told the court this morning that this had not taken place yet.

Judge Paul Kelly asked what the reason for the delay was and was told by Mr Lannon that Castlerea Prison does not have the facility to have a psychiatric assessment.

Garda Inspector Goretti Sheridan said a doctor from the Central Mental Hospital in Dundrum had contacted Castlerea Prison describing it as "a work in progress."

Judge Kelly then ordered Mr Cuddihy to be remanded in custody to appear at Harristown Court on 7 November.

Mr Cuddihy waved and greeted relatives when he arrived in the court but did not speak during the brief hearing.

He is charged with two counts of murder in or around 22 October.

The bodies of Kathleen and Jimmy Cuddihy were found at their home at Churchtown in Carndonagh last Thursday.
