The two boys who murdered Kildare schoolgirl Ana Kriegel are due back in court today for their sentence hearing.

They were convicted in June of her murder, and one of them was also found guilty of aggravated sexual assault.

Their sentencing hearing is due to get underway later this morning.

It was previously adjourned to allow for various reports to be compiled – including psychiatric and psychological assessments.

The boys were just 13-years-old when they murdered Ana Kriegel in a derelict farmhouse in Lucan on May 14th last year. She was one year older.

They’re both now 14, and because they're still considered children in the eyes of the law, their identities have been, and always will be, protected.

They have been held at Oberstown Detention Centre since they became Ireland’s youngest ever convicted murderers back in June.

During their lengthy trial, the jury heard BOY B lured Ana from her home in Leixlip to a derelict farmhouse in Lucan where BOY A was waiting for her.

Both were convicted of murder, and BOY A was also found guilty of aggravated sexual assault.

Their sentence hearing was due to take place in July, but a delay with certain medical reports resulted in it being adjourned until today.

Neither boy was present when the case was mentioned last Friday, but the prosecuting barrister told the court that all the reports were now ready.

The judge has restricted the number of journalists allowed into the actual courtroom to just five, but a live video and audio feed can be accessed from another courtroom for the additional journalists expected to attend.

Mr Justice Paul McDermott said he felt it was necessary to reduce pressure on the boys at a time that is extremely difficult for them and their parents.
