The jury in the Gable Tostee trial has indicated it is struggling to reach a verdict over whether he killed Tinder date Warriena Wright, who fell off his 14th floor Gold Coast apartment balcony.
Tostee, 30, could be found guilty of the murder or manslaughter of New Zealand tourist Warriena Wright.
In August 2014, the pair had been on a first date which turned violent and saw Tostee lock Ms Wright on the balcony of his 14-floor Surfers Paradise apartment.
Shortly after she fell to her death trying to scale the balcony.
The jury of six men and six women began deliberations yesterday afternoon, but sought extra instruction from Justice John Byrne this morning and again this afternoon.
Their deliberations continued until about 5.30pm this afternoon when they were sent home for the night, to meet again in the morning.
Justice Byrne said he would only discharge them if he was genuinely satisfied they could not reach a verdict after further deliberations.
“You are entitled to take as long as you wish to reach your verdict,” he said.
“Judges are usually reluctant to discharge a jury because experience has shown that juries can often agree if given enough time to consider and to discuss the issues.”
Justice Byrne reminded the jury to listen “carefully and objectively” to their fellow jurors.
“This often leads to a better understanding of the differences of opinion you may have and may convince you that your original opinion was wrong,” he said.
“That is not of course to suggest you can, consistently with your oath or affirmation as a juror, join in a verdict if you do not honestly and genuinely think that it is the correct one.”
