HUNTER: Suspected serial killer David Snow charged in 1991 cold case murder

Article content
David Alexander Snow wouldn’t look out of place with a bookkeeper’s pocket protector stuffed in his short-sleeve shirt.
But Snow, now 70, is nothing so innocuous.
He is a suspected serial killer.
On Monday, the OPP announced that they had arrested and charged Snow in a long-unsolved cold case murder in the Bancroft area. A dangerous offender, Snow is currently under lock and key at Millhaven.
“Angelien Quesnelle was murdered in 1991 and, for 34 years, her family has lived without answers. OPP investigators have never stopped searching for her killer, relentless in their pursuit of the truth. This arrest represents an important step toward providing Angelien’s family and the community of Apsley with the long-awaited answers they deserve,” OPP Det. Insp. Shawn Glassford said in a news release.
Less than a year later, Snow killed again.
Cops say that on Oct. 9, 1991, Quesnelle, 40, of Apsley — between Peterborough and Bancroft — was reported missing. She had disappeared on Oct. 7, after being seen in Peterborough around noon.
One month later, her vehicle was found in an abandoned quarry in the area of Ridge Rd. and Hwy. 620, east of Coe Hill. OPP investigators found several personal items nearby. On Nov. 15, 1991, a hunter discovered her body. A post-mortem deemed her death a homicide.
On Thursday, detectives arrested and charged Snow. He remains in custody.
In 2019, Snow tossed a Hail Mary in the hopes of winning parole, but the sadistic sex offender’s gambit fell short. The details of his parole hearing are shocking.

Known as the “House Hermit,” Snow is serving a life sentence for the first-degree murders of Toronto realtor Ian Blackburn, 55, and wife Nancy, 49, in April 1992. He was living in their Caledon property, took them hostage and stole their firearms, the decision noted.

Snow put the hog-tied, strangled Nancy Blackburn into the trunk of her car and forced her husband at gunpoint to drive to the couple’s north Toronto home. He asphyxiated Ian and left both bodies in the trunk in their driveway.
The killer then boarded a train for Vancouver, where he used his victims’ guns to terrorize women in the Pacific coast city. Snow kept one woman as a sex slave for eight days in one of the area’s forests. She was one of his three West Coast victims.
“I was like a toy to him,” the woman said in 1992. “It was like he was watching some pornographic movie and I was sexually assaulted every day.”
She added: “He didn’t see me as a human being. He would do what he pleased with me.”
According to the National Parole Board, Snow had only recently grasped his twisted obsession with evil sexual fantasies “fuelled by pornography”, the Toronto Sun‘s courtroom legend, Sam Pazzano, reported in 2020.
Snow told one victim: “I’m going to f— you to death.”
The parole decision noted that the double-killer “was caught with pornography” in his prison cell before taking the Long Term Sex Offenders program in 2000. He was convicted of more than 20 criminal offences, including two murders, kidnapping, sexual assault causing bodily harm, and sexual assault.
Snow had been diagnosed with several sexual deviancies – sexual sadism, preoccupation with anal intercourse, erectile dysfunction, antisocial personality and narcissistic personality disorder.
Snow “didn’t agree with” the diagnosis. Of course, he didn’t.
