Summary
A three-part series—A man walking home from work suddenly hears screams coming from a house... then a single sharp crack.
He follows the sound to the garage, where he finds a woman bleeding out on the floor.
It's JoAnn Wilson, mother of three and ex-wife of Colin Thatcher, a high-profile Saskatchewan politician.
Her murder was the tip of the iceberg of a decades-long saga that gripped the nation and drew comparison to the show Dallas — but would prove far darker than anything on TV.

| 0:00.0 | Canadian true crime is a completely independent production, funded mainly through advertising. |
| 0:04.7 | The podcast often has disturbing content and course language. It's not for everyone. Please take |
| 0:10.0 | care when listening. Hi there. I hope you're well. As I mentioned in the update a couple of weeks ago, |
| 0:16.7 | this is a carefully selected replay from the archives as we prepare to return with new episodes |
| 0:23.1 | in late April. Thanks so much for your patience. Many of us have watched Yellowstone, the glossy, |
| 0:30.8 | modern Western TV show about the fictional Dutton Family Ranch. There's a powerful family patriarch with a giant ego who becomes |
| 0:40.5 | the governor of Montana. There's high stakes family disputes, calculating power and land grabs, |
| 0:47.6 | and a lot of moral ambiguity. Eventually, all subtlety packed up and left the ranch. |
| 1:00.4 | The characters became self-parodies, and storylines spun in circles like that spinny horse maneuver that creator Taylor Sheridan seemed obsessed with. |
| 1:04.9 | Decades before Yellowstone, the TV show Dallas did something similar with the ruthless Ewing family's fictional oil and ranching empire in Texas. |
| 1:16.0 | While Dallas also leaned into melodrama, a real-life version of that story was unfolding just over the Canadian border. |
| 1:25.2 | And that's today's case. |
| 1:27.6 | Colin Thatcher came from a prominent ranching family in the prairies. |
| 1:32.1 | His father, Ross Thatcher, was the Premier of Saskatchewan, |
| 1:36.3 | and Colin followed him into politics. |
| 1:39.3 | Publicly, he was ambitious, influential, and a little chaotic. |
| 1:44.1 | Privately, his marriage was collapsing |
| 1:46.5 | into hostility, legal fights and escalating tension that eventually spilled into the public. |
| 1:54.0 | Then, his wife Joanne, mother of their three children, was found dead in her garage. The case gripped the nation. People drew parallels |
| 2:04.7 | to the TV show Dallas, comparing Colin Thatcher to the fictional oil tycoon J.R. Ewing, |
| 2:12.5 | scheming, manipulative, controlling, and always two steps ahead. |
| 2:23.2 | This case would turn out to be far darker than anything on scripted TV. |
