Initial findings into the high-rise balcony death of a Gold Coast Titans cheerleader may be flawed, based on new evidence, a biomechanical expert has told a murder committal hearing.
It is alleged Jayden Moorea, formerly known as Dan Shearin, threw his Gold Coast Titans cheerleader girlfriend Breeana Robinson, from the 11th storey of a Southport apartment on January 29, 2013.
Mr Moorea is facing a murder committal hearing in the Southport Magistrates Court to determine if there is enough evidence to go to trial.
The court heard key evidence from biomechanical expert Dr Zachariah Couper, who said in his initial statement that Ms Robinson's body was in a position consistent with someone "having been thrown" from the balcony.
Ms Robinson's body position was fundamental to the case being reopened in 2019.
But conflicting evidence given by witnesses on the position Ms Robinson fell cast doubt over Dr Couper's conclusions.
Prosecution taking the weekend to consider
During cross-examination, defence barrister Angus Edwards recalled evidence from Gordon Cassidy, the security guard who moved Ms Robinson's body to perform CPR before paramedics arrived.
He also recalled conflicting witness testimonies from several building residents about the way Ms Robinson fell.
Dr Couper said the evidence "may have a significant impact" on his conclusions.
Magistrate Catherine Pirie asked whether the hearing should be adjourned until a new biomechanics report could be conducted.
She said Dr Couper "needed to be provided with the actual evidence, the transcript of what witnesses say … because this is an important piece of evidence".
"I haven't had to deal with this in more than 20 years," Magistrate Pirie said.
The prosecution will take the weekend to decide and a determination of the remodelling will be decided on Monday.
Police officer did not take notes at scene
Earlier on Friday, Senior Constable George Liasides told the court the biggest regret of his career was "not recording" at the scene.
Senior Constable Liasides told the court Mr Moorea spoke of a "fight" he had with Ms Robinson on the night she died.
But the policeman said he had not asked if it had been verbal or physical.
During cross-examination, Mr Edwards questioned why Senior Constable Liasides failed to take notes at the scene.
"The things that were said stuck with me, so I remember them."
Senior Constable Liasides recalled the conversation to be "odd" and "concerning", but failed to take notes on the night.
He told the court he had felt regret for "a long time".
"There's certain jobs you go to in your career you think about a lot and you wish the outcome could be different," he said.
"I've regretted that job ever since going to that job on the night that it happened — I regretted that job in its entirety."
