Simon Gittany, who threw his girlfriend off a 15th-floor balcony in a fit of jealous rage, will be be sentenced next week, after a hearing that featured dramatic new testimony and a bizarre protest staged by his new girlfriend outside court.
Gittany was convicted late last year of murdering his fiancee, Lisa Cecilia Harnum, after he learned she was planning to leave him and return to her native Canada.
The trial heard that the 40-year-old installed hidden cameras in their Sydney apartment, spied on Harnum's text messages and made her quit her job and stop seeing her friends.
Gittany claimed she jumped off the balcony. During a two-day sentencing hearing which ended yesterday, the Crown produced a new witness, who testified that before she died he had repeatedly threatened to kill her and "make it look like suicide".
The woman, who asked not to be named but attended a hair and beauty college with Harnum, 30, said her friend had been afraid that Gittany would poison her food.
