A Supreme Court jury will continue deliberations in the trial of a Youngtown woman accused of punching her then-boyfriend in the eye causing him grievous bodily harm.
Lisa Maree Doolan, 47, has pleaded not guilty to the allegation on June 5, 2016.
The jury of seven women and five men retired to consider their verdict at 3pm on Tuesday.
Justice Robert Pearce told them he could take a majority verdict, 10 or more jurors, after two hours of deliberation but the jury went home at 5pm.
An alternative verdict of assault was left open for the jury if it believed Ms Doolan did not intend to cause grievous bodily harm.
Early on Tuesday Ms Doolan gave evidence that she and Shannon Watson argued for 5-10 minutes when he arrived at her home after a function.
But she denied any physical contact. She said she had felt trapped and scared that he kept turning up.
Last week Mr Watson told the court that she had "fired" three punches at him, the last of which hit him "square in the eye."
He had undergone a corneal transplant the week before and the injury resulted in removal of his eye.
Defence counsel Fran McCracken suggested that the issue of the trial was "whodunnit" .
"Can you be satisfied beyond reasonable doubt that the injury was caused by Lisa Doolan," she asked.
Crown prosecutor Luke Brett cross examined Ms Doolan about a claim made three times in a police interview that she had called an ambulance to attend to Mr Watson.
A recording of a triple zero call revealed that Mr Watson's sister Kristie McLaren called the ambulance.
"Her credibility as a witness is not great and her evidence should not be accepted," Mr Brett said.
Mr Brett said the Crown's case was supported by the evidence of expert witness Dr Nicholas Downie, who said only blunt force trauma, not vomiting, which had been suggested by the defence, could have caused such a catastrophic injury.
