The forensic expert advised that the DNA from Lees’s T-shirt was 150 quadrillion times more likely to have come from Murdoch than someone else.
Then a detective – the one Gwynne had chosen for her acute attention to detail and who had sifted through thousands of Murdoch’s belongings – discovered a small, round, Mary Jane hair tie.
“It was the hair tie that was taken from Joanne Lees when she struggled to survive and keep her life. [Murdoch] had it wrapped around his shoulder holster, inside his belongings. I think it was a trophy but no one will ever know.”
Months later, when the hair tie was presented as evidence in the trial, it clearly made an impression on Murdoch.
“He recoiled and he wouldn’t touch it,” recalls Gwynne. “You could see that he knew that was it. That was the nail in his coffin.”
