Birchmore trial turns on disputed evidence and police failures
Legally Brunette: Sandra Birchmore Pt. 2 with Andrea Canning
The case tests how investigators, forensic experts, and federal prosecutors interpret a death first classified as suicide.
- 1Prosecutors allege Matthew Farwell groomed Sandra Birchmore and killed her after her pregnancy threatened to expose their relationship.
- 2Texts, surveillance footage, paternity evidence, and disputed forensic findings leave both sides competing over the death’s narrow timeline.
- 3The investigation’s failures and the broader crisis of missing and murdered Indigenous women widen the case beyond one courtroom.

Andrea explains how surveillance, digital records, crime-scene details, and renewed forensic scrutiny challenged the original suicide ruling.
The brief
Emily Simpson and Shane speak with Dateline correspondent Andrea Canning about Sandra Birchmore’s death, the federal charges against former officer Matthew Farwell, and allegations that he groomed Birchmore while she was underage.
Tens of thousands of texts, pregnancy and paternity evidence, and Farwell’s other relationships shape the central question: what did he know, and what motive did the pregnancy create?
The prosecution points to surveillance, phone and Apple Watch data, a broken necklace, hair on a duffel-bag strap, and forensic opinions suggesting a struggle; the defense emphasizes uncertainty and the undetermined ruling.
Andrea describes how an initially inadequate investigation gave way to renewed scrutiny involving Birchmore’s family, Chief Donna McNamara, the FBI, and federal prosecutors.
The conversation closes by connecting Birchmore’s case to missing and murdered Indigenous women, including Andrea’s reporting on Olivia Lone Bear and Lissa Yellowbird’s advocacy.
