A pregnant Co Armagh woman was killed in a "prolonged assault", a murder trial has heard.
Natalie McNally, 32, was killed at her home in Lurgan a week before Christmas in 2022.
Stephen McCullagh, 36, of Woodland Gardens in Lisburn, has denied murdering his girlfriend Ms McNally, who was 15 weeks pregnant with their child.
A jury of six men and six women has been sworn in to serve during the trial, which is expected to last for around five weeks, before Judge Mr Justice Patrick Kinney.
Yesterday, prosecuting barrister Charles MacCreanor KC set out their case that Ms McNally's murder was "planned, calculated and premeditated, one which he (McCullagh) hoped to get away with".
Ms McNally's time of death has been estimated to be between 8.50pm and 9.30pm on 18 December 2022.
The emergency services were alerted the following evening on 19 December.
State pathologist for Northern Ireland Dr James Lynas, who carried out a post-mortem examination of Ms McNally on 21 December 2022, gave evidence to the trial today.
He said her death was caused by compression of the neck, stab wounds to her neck and blunt force trauma to her head, and detailed bruising and injuries across her head, neck and arms, as well as internal injuries.
"A male foetus of approximately 15 weeks gestation was within the womb... It seems likely that the foetus died as a result of the assault," he added.
Dr Lynas described Ms McNally as being of a slim build and 5ft 5 (165cm) in height, and tests having shown no alcohol in her blood at her time of death, but a therapeutic concentration of an anti-depressant medication.
He said bruising on the left and right side of her neck had a circular profile suggestive of having been caused by finger tips, "as may have occurred if the neck had been forcibly grasped by a hand".
Meanwhile he said the type of bruising on the left side of the neck may suggest that a ligature had been tightened around it, but also said such bruising may have also occurred if her neck had been gripped, particularly if there was "interposed clothing".
He said the compression of the neck could have caused her to rapidly lose consciousness, and if sustained, caused her death.
However there were also three stab wounds to her neck caused by a bladed weapon which, he said without medical attention, would have been expected to bleed quite rapidly and would have caused her death.
A third area of injuries were lacerations to her head, "in keeping with her having sustained at least five heavy impacts to the head", which could have been caused by an object with a semi-sharp edge, such as the corner of a piece of furniture.
"There were also multiple bruises of the scalp and face, again in keeping with her having sustained additional blunt impacts, some possibly the result of blunt blows such as punches," he added.
"Microscopic examination of the brain by a specialist neuro pathologist revealed evidence to suggest that she possibly survived in her moribund condition for a short period of time."
Dr Lynas said bruising to her left wrist and right arm may suggest raising her arms to protect herself, while the finding of food in her lungs further indicates she may have survived for a short period of time in an unconscious state.
He said he believed it had been a "prolonged assault".
"This is a complex case, and it is difficult to be certain of the exact fatal sequence from the autopsy findings alone," he said.
"Both the neck compression and the stab wounds of the neck could have caused her death on their own... It is difficult to completely exclude the possibility that the multiple severe head injuries she had sustained may have played some part in the overall fatal sequence.
"The compression of the neck, stab wounds of the neck and blunt force trauma of the head all contributed to the fatal outcome."
Earlier, the court heard Mr McCullagh told police at the scene that her ex-partner was responsible.
Sergeant Stewart attended the scene at Ms McNally's house on the night of 19 December and described seeing Mr McCullagh "very upset", and seeing him being led out of the house by a colleague.
He said Ms McNally was lying on her back at the top of the stairs in the townhouse, beside the living room in the property, with blood visible around her and a puncture wound on her neck.
He also saw a small black-handled knife lying on the floor of the living room and blood on the wall.
The sergeant said he briefed the on-call duty detective sergeant that night for Lurgan CID by telephone.
He said Mr McCullagh was arrested at around 11.40pm and taken into custody at Banbridge police station.
The on-call detective sergeant also gave evidence to the trial.
He said he briefed a senior officer who instructed him that the incident should be treated as murder.
He agreed that Sgt Stewart told him Mr McCullagh had told police at the scene: "I know what has happened, the ex-partner has done this", and that he had directed Mr McCullagh to be arrested for murder.
Constable Orr, who arrested Mr McCullagh, said he said: "Murder, why?" in response to being arrested.
The trial continues and will hear the defence case set out by barrister John Kearney KC later this week.
