HORACE Lorenzo Lyken Jones kept his head down as graphic images of his mother's dead body were shown to a jury yesterday.
But then it all became too much.
Visibly distressed, the 21-year-old had to call for a break on day two of his trial in the Rockhampton Supreme Court.
Jones has pleaded not guilty to murdering his mother, Roxane Gilbert, at his Gladstone home on June 29, 2012.
Ms Gilbert lived in Bundaberg, but often visited Gladstone.
The body of Ms Gilbert, 38, was found wrapped in a tarp on the backseat of her car, which had been dumped in swamp land near the Calliope River.
Forensic pathologist Dr Nigel Buxton gave evidence about her injuries yesterday.
Describing Ms Gilbert's injuries as "quite extensive", Dr Buxton said there were 17 wounds on her head and neck alone.
"Some are quite dramatic," he told the court.
When shown a 64cm long samurai sword and smaller kitchen knife, alleged to be the murder weapons, Dr Buxton agreed they could have caused the injuries.
He said there were two stab wounds to Ms Gilbert's chest, one going through the lung to the back of the chest wall, and moderate force would have been required to cause such injuries.
As a photo of a deep cut to Ms Gilbert's arm was shown to the court, Jones beckoned to his solicitors who then called for an adjournment.
A short time later, Justice Duncan McMeekin told the court Jones had become physically unwell and would be not returning for the remainder of Dr Buxton's testimony.
Earlier in the day, a recording of a police interview with Jones on July 2, 2012, was also played for the jury.
During the interview, Jones described his relationship with his mother as "crazy" and "dark".
The court heard he believed Ms Gilbert was being paid for sex.
He told police he was kicked out of home when he was in Year 7, after he confronted her about her lifestyle choices.
Jones also said Ms Gilbert drank most nights and would often go "ballistic" at him.
He said on the day of her death she was "not acting like mum".
"She was really drunk and disorderly," he told police.
The trial continues today.
