The family of a nurse has welcomed her killer being found guilty of murder 33 years after she went missing on Sydney's north shore.
Robert John Adams was convicted on Friday over the death of Sydney nurse Mary Louise Wallace in 1983 following a judge-alone trial.
The court heard advances in technology allowed authorities to match hairs seized from Adams' car boot to strands from Ms Wallace's hairbrush.
"We've waited 33 years for this decision," Ms Wallace's sister Anne Fraser said outside court.
"...I didn't believe it, it'll take a while to sink in.
"We've known since the first week (it was Adams) and it's just thanks to police."
Adams was taken into custody following the verdict and is due to face a sentence hearing in February.
