The Ana Kriegel trial has heard that her DNA and the DNA of one of two boys accused of her murder was found on a mask seized from the boy’s home.

The boys, who are both aged 14, deny murdering the Kildare schoolgirl at a derelict farmhouse in Dublin last May.

The prosecution claims Boy B lured Ana Kriegel from her home in Leixlip on the evening of May 14th last knowing what was going to happen to her.

Boy A is accused of violently sexually assaulting and murdering her.

This afternoon, forensic scientist John Hoade was recalled to give evidence about his analysis of a number of items found in a backpack in Boy A’s bedroom.

He said Ana’s blood was found on the bag itself as well as on a mask, some gloves and knee pads contained inside.

No blood was found on some plastic shin guards and a woollen snood that were also in the bag.

The mask, which was shown to the jury this afternoon, was described as a “half-mask” showing eyes and a hole for the nose. The area around the eyes was black, extending to green and the bottom of it was jagged with red around the mouth.

Mr Hoade said he developed a mix DNA profile, containing all the elements of Boy A’s DNA profile and of Ana’s on the mask.

Earlier, the trial heard that a forensic analysis of Boy A’s phone revealed data from a few months beforehand relating to “15 gruesome torture methods in history” and “Horror movies that will blow everyone away.”

The jury heard the words “Abandoned places in Lucan” were also found during the analysis.

Garda Thomas Doyle told the court that, during questioning, the boy told him that he was looking for horror movies online.

He also said he did not have Safari on his phone.

Boy A was also presented with part of a statement made that day by his co-accused and when asked if he had any additions or clarifications to make to his own statement, he accused the other boy of lying.
