The murder trial of Brisbane socialite Maureen Boyce, who was found dead with a knife her abdomen, is nearing its end.
New Zealand-based doctor Thomas Christopher Lang is on trial in the Brisbane Supreme Court after pleading not guilty to fatally stabbing Ms Boyce in her Kangaroo Point sub-penthouse in 2015.
Defence barrister Tony Glynn QC and Crown prosecutor David Meredith are expected to give their closing arguments on Monday, followed by Justice Peter Flanagan's final directions to the jury.
The court has heard Ms Boyce was discovered in bed on the morning of October 22 with a knife so deeply embedded in her stomach that part of the hilt was inside her body.
Mr Meredith told the jury at the start of the trial that they must decide whether the 68-year-old, who had a history of depression, took her own life or if she was killed by Lang in a "jealous rage".
