Yves Grenier Charged With Murder in 2022 Penticton Double Homicide

Alannah Brown and her boyfriend Douglas Barker, both 30, were found dead inside a torched vehicle near the Kickininee Provincial Park pullout on Sept. 15, 2022. Three and a half years later, the RCMP's E-Division District Major Crime Unit has charged a fifth person in connection with their deaths: Yves "Oliver" Grenier, 36, facing two counts of first-degree murder.

The BC Prosecution Service approved the charges against Grenier on March 6, 2026. He was arrested the same day and remains in custody.

The investigation, filed under RCMP case number 2022E-16671, stretched across more than three years of evidence collection, witness interviews, and forensic analysis before reaching this point. Four people had already been charged in 2025 before Grenier's arrest. In July 2025, the BC Prosecution Service charged Jilane King with first-degree murder of Barker and accessory after the fact to both homicides. Simon Bourbonnais faced a broader set of charges: accessory after the fact to the murders of both Barker and Brown, unlawful confinement of Brown, indignity to human remains of both victims, and manslaughter in Brown's death. Tyler Stuart was charged with accessory after the fact to both murders and indignity to human remains. A fourth suspect charged in July 2025 has not been publicly named by police. One additional person was charged in November 2025, also unnamed in available records.

BC RCMP Superintendent Sanjaya Wijayakoon addressed the Grenier arrest directly: "This was an extensive and complex investigation. We have now charged and made our final anticipated arrest for this investigation. Our thoughts remain with the families of Mr. Barker and Ms. Brown, and we hope that today's charges provide some measure of progress as the matter proceeds before the courts."

The RCMP has confirmed this represents the final anticipated arrest in the investigation. With the case now before the courts, investigators have stated no further information will be released. Motive, the specific evidence tying Grenier to the scene, and scheduled court appearances remain undisclosed.
