How do you convict a killer with no DNA, no fingerprints and no weapon?

In 2005, 14-year-old Chelsey Acorn was murdered and buried in a shallow grave beside the Coquihalla River near Hope, BC. Two men confessed to undercover police: Jesse Blue West and his son, Dustin Moir. But the confessions didn’t match. Once the case reached court, each man told a new story in which the other was the killer and he was only the one who helped bury her.

In Part 2, I break down how the Crown proved murder using almost nothing but the killers’ own words. The evidence includes a borrowed shovel, four secret details only the killers could know, a newspaper clipping hidden in a safe, and a recorded conversation in the back of a sheriff’s van where the father told his son, “It wasn’t all me.”

You’ll hear how a joint trial fell apart 8 weeks in, and why a jury’s murder conviction was overturned on appeal. You’ll also hear how the Supreme Court of Canada’s ruling in R. v. Hart changed the rules for Mr. Big investigations in the middle of the case, which forced the Crown to fight for the son’s confession all over again.

Along the way, I explain in plain language what makes a murder first-degree, how the law separates a murderer from an accessory after the fact, and how judges decide whether to believe someone who takes the stand.

It took three trials and more than a decade to get there.

Content warning: this episode discusses the murder of a child and the sexual exploitation of youth.
