Schoolgirl Ana Kriegel was struck several times with a weapon as she lay on the floor in the room where her body was found, a blood-spatter expert has told a trial.

The blood spatter patterns near the doorway in the room also indicated her head was in contact with the wall when she was struck, John Hoade, an expert in blood pattern analysis with Forensic Science Ireland, said in his evidence.

He also said blood-spatter patterns indicated that Ana was assaulted when she was upright at the back of the room.

Mr Hoade told the Central Criminal Court trial of two 14-year-old boys accused of murdering Ana that he visited Glenwood House in Lucan on May 18 and May 20, 2018.

He was aware that Ana's body had been found on May 17. He had been told she had been assaulted and there was a laceration to her head that had bled.

The jury heard that Ana "bled from her injuries" and Mr Hoade agreed with prosecution counsel Brendan Grehan SC that there was "quite an amount of blood".

Mr Hoade said swabs were taken from the blood samples on the wall and floor and the DNA profile of the blood matched the DNA profile taken from Ana during the post-mortem.

Mr Hoade said that when he attended the scene on May 18, he noted a number of types of blood staining, including saturation blood staining, impact pattern staining, cast-off pattern staining and swipe staining.

He pointed out seven areas of blood staining in the room on a 3D reconstruction of the crime scene to the jury.

Mr Hoade said that impact spatter on the wall and saturation staining on the carpet indicated that Ana was "struck several times with a weapon" in this location.


This staining was in the corner on the left side when you entered the room, Mr Hoade told Mr Grehan.

Saturation blood staining on the carpet would also indicate that Ana lay in that position for some time after she was assaulted, though Mr Hoade said he could not say how long she had lain in that area.

Mr Hoade said that Ana's body had subsequently moved or been moved to the back of the room, where her body was found.

He added that the carpet in this area near the door had been "saturated with blood".

Blood-spatter patterns on the wall just above the skirting board also indicated that Ana's head was "in contact with the wall when she was struck", Mr Hoade said.

He also said there were patterns showing blood staining resulting from an object striking liquid blood as well as cast-off patterns showing blood, which was flung from a weapon.

Mr Hoade said that blood patterns on the wall at the back of the room were higher than the skirting board.

These indicated Ana had been assaulted when she was upright at the back of the room.

A "swipe pattern" on the skirting board indicated that Ana had contact with this area while bleeding or an item wet with her blood had been in contact with it, he said.

Mr Hoade said that he examined a white stick and a concrete block found in the corner of the room. These items were in situ when he examined the scene, which was a visual examination.

The two youths, aged 13 at the time, have pleaded not guilty before the Central Criminal Court to murdering Ana (14) at Glenwood House, Laraghcon, Clonee Road in Lucan on May 14 last year.

One of the accused, Boy A, has also denied a charge of aggravated sexual assault.

It is the prosecution's case that Boy B "lured" Ana to the derelict farmhouse and then watched as the other boy sexually assaulted and murdered her.

Earlier, Detective Garda Gabriel Newton gave evidence of collecting the clothing which Boy A and Boy B were wearing on the day Ana went missing.

Det Gda Newton, who was investigating an alleged assault on Boy A at the time, called to his home at 7pm on May 16, 2018.

She said she told Boy A's parents that any evidence on the boy's clothes could be helpful if the culprits were found.

The jury was shown the items given to Det Gda Newton by Boy A and his parents, namely a black hoodie top, white T-shirt, black boots and grey/black bottoms as well as a mobile phone.

Det Gda Newton said Boy A's mother told her she had washed the clothes twice.

The jury was told that Det Gda Newton called to Boy B's home on May 17, 2018.

Boy B was in the kitchen when his mother handed over his clothes, the court heard.

These clothes, consisting of a pair of blue runners, a grey hoodie, black bottoms and a white polo T-shirt with a navy collar, were also shown to the jury. Det Gda Newton said she then handed the two boys clothes to the exhibits officer in the case.

The trial continues this morning before Mr Justice Paul McDermott and a jury of eight men and four women.
