The murder trial of retired Tauranga doctor, who is accused of murdering Australian socialite Maureen Boyce, is nearing its end.
Lang is on trial in the Brisbane Supreme Court, in Australia, after pleading not guilty to fatally stabbing Boyce in her Kangaroo Point sub-penthouse.
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.
It's reported that Lang had gone to Brisbane for love and was arrested on Friday October 23 2015 and taken to Dutton Police Station for extensive questioning over Maureen's death.
This followed a 12-hour questioning period which took place on Thursday October 22 2015.
Maureen's body was found on the Thursday morning in her Kangaroo Point sub-penthouse.
She had a single stab wound to her abdomen.
Lang's relationship to the former model was unclear, except for police confirmation that he was staying in the Macleay Towers apartment and knew Maureen “quite well”, the Brisbane Times reported at the time of Lang's arrest.
