Final Justice: The Murder of Guylaine Potvin

Episode 369: In the quiet city of Jonquière, Quebec, the brutal 2000 murder of 19-year-old Guylaine Potvin sent shockwaves through her community and left investigators baffled for over two decades. For years, the case grew cold, with few leads and little hope for justice. But in 2022, a remarkable breakthrough in forensic science and persistent detective work finally led to the arrest of Marc-André Grenon, a man whose name had lingered on the periphery of the investigation for years. This episode takes you inside the investigation, the science that cracked the case, and the long-awaited trial that brought answers to a grieving family. Sources:⁠2024 QCCS 551 (CanLII) | R. c.
