On Tuesday in the NSW Supreme Court, Justice Ian Harrison's focus was on one thing - did Chris Dawson murder his wife Lynette?
He concluded yes after summarising in a five-hour long judgement the details that led to that fateful day on January 8, 1982.
Watch the Chris Dawson verdict here:
Dawson had a strong motive - something the Crown called "out with the old in with the new." The new being his teenage student whom he'd allegedly groomed before having sex with.
As Justice Harrison went through Dawson's movements in meticulous detail, he also went through those of 16-year-old 'JC,' as she was known to the court.
It made me sad. And mad. And horrified. She was not the focus of this trial, but to hear how this teenager's life was steamrolled by this man was just another element that made the whole judgement hard to listen to.
A then 33-year-old Dawson was a PE teacher at Cromer High. He first pursued JC through the final years of high school, leaving notes of love and affection in her schoolbag in 1980 and 1981. The Australian reports he had noticed her in Year 10, and altered the roll to ensure she would be in his class.
