A Scots pensioner who brutally murdered his ex-girlfriend in Canada has died in prison without revealing the location of her body.
Andrew Watson, 84, bludgeoned Lise Fredette to death with a shovel before putting her corpse in his car and dumping it at an unknown location.
The 74-year-old's body has never been found and Watson refused to disclose her whereabouts.
Watson, originally from Glasgow, was found guilty of murder by a jury in Ontario in April 2017 and was given a life sentence with no possibility of parole for 25 years.
Prison authorities said he died of "apparent natural causes" on Saturday at the Millhaven Institution in Ontario.
At Watson's trial, prosecutors told jurors that he was a "jilted and controlling" ex-boyfriend and he had killed Miss Fredette as the "final act of harassing her".
He was arrested ten days after the grandmother was last seen leaving her job at Walmart on November 12, 2014. Her glasses and keys were found next to her car at home and there was blood in her driveway.
At the sentencing hearing, Miss Fredette's children appealed directly to Watson to tell them where he had buried their mother but he refused.
After learning of Watson's death, his victim's son Stephane Leclerc, 56, told Canadian newspaper The Peterborough Examiner: "I know he suffered a great deal and he's going to hell because he deserves it.
"All your hopes just go down the drain. Now my hopes of ever finding my mom just went down to zero.
"He never said where he hid my mom, so now that he's dead, I doubt I'll ever find her. That's the part that really worries me.
"Maybe at one point he mentioned something and somebody listened. Hopefully he told a nurse or doctor when he was delirious."
Watson and Miss Fredette met at a dance in Peterborough, where they both lived, in 2011 and dated on and off for a few years before their relationship ended for good in April 2014.
Miss Fredette started dating another man a few months later but Watson wouldn't leave her alone and would sit outside her home and bombard her with letters.
Earlier this year, Miss Fredette's children launched a lawsuit against Watson for damages of £784,000.
They asked for damages for loss of care, guidance and companionship and for nervous shock and mental stress.
In a statement, the Correctional Service of Canada said: "On July 9, 2022, Andrew Watson, an inmate from Millhaven Institution's Regional Treatment Centre, died while in our custody of apparent natural causes.
"At the time of death, the inmate had been serving an indeterminate sentence for first degree murder, which commenced on April 24, 2017.
"As in all cases involving the death of an inmate, the Correctional Service of Canada (CSC) will review the circumstances. CSC policy requires that the coroner be notified."
