Testimony from a blood spray pattern expert is set to be heard in the North Carolina murder trial over the killing of Irish businessman Jason Corbett (39).

The Limerick-born packaging industry executive and father-of-two died from at least 12 severe blows to the head in his US home on August 2, 2015.

Such was the violence of the blows that parts of Mr Corbett's detached scalp and hair were found in both the master bedroom and hallway of his Panther Creek property.

His blood was found on the floor, walls, bed, bedclothes, bathroom and even utility equipment.


Two implements were used - a 28in Louisville Slugger baseball bat and a garden paving brick, Davidson County Superior Court heard.

Mr Corbett's blood was found on both the bat and brick while his hair was discovered imbedded in the paving stone.

Molly Martens (33), his second wife, and Thomas Michael Martens (67), his father-in-law, a retired FBI agent and lawyer, both deny second degree murder. They have argued self-defence and claimed Mr Corbett attacked his wife and threatened to kill her.

Her father said he then intervened and struck Mr Corbett to defend them both.

However, both father and daughter were found by police and paramedics at the scene with no bruises, cuts, abrasions or visible wounds.

The trial will resume for the 10th day with continuing evidence from Lieutenant Frank Young, Davidson County crime scene examiner.

He has revealed that a blood pattern expert examined the scene and photographs of the markings singled out by the expert have already been shown to the jury.

An analysis of the blood spatter marks in all the rooms - but particularly the master bedroom - will focus on where Mr Corbett's head was positioned when it was struck repeatedly by the two objects.

The angle and spray pattern of the blood found on the walls will be used to determine Mr Corbett's posture when he was being struck.

Pathologist Dr Craig Nelson has already indicated that at least one of the major blows suffered by Mr Corbett was sustained after he died. Two head-shaped blood imprints on the wall of the bedroom were found to be at a relatively low level.

Furthermore, substantial quantities of blood were found on the bedroom skirting board. Lt Young said that blood was also found on a vacuum cleaner - and the blood-drip patterns on the machine indicated that it had been moved by someone at the scene.


"It was as if it was laid down and moved back up," he said.

The expert will also address a number of as-yet-unexplained indentations on the plaster walls. These were of such significance they were specially circled on photographs of the scene taken by Lt Young.

Dr Nelson said Mr Corbett suffered at least 12 major blows - but such was the catastrophic damage to two rear portions of his skull, where multiple impacts had been sustained, that it was impossible to make an accurate count.

One skull wound, which had a linear detail imprint, was assessed as not having been made by the baseball bat.

The trial continues today.
