Man Charged with First-Degree Murder in 2022 Penticton Couple Homicide
Yves "Oliver" Grenier, a 36-year-old man, has been formally charged with two counts of first-degree murder in connection with the tragic deaths of Douglas Barker and Alannah Brown, both aged 30. The charges stem from a double homicide that occurred nearly four years ago in Penticton, British Columbia, marking a significant development in a complex and lengthy investigation.
Discovery of the Victims
The investigation began on September 15, 2022, when Royal Canadian Mounted Police officers discovered the bodies of a man and woman inside a torched vehicle near the Kickininee Provincial Park pull-out. The victims were later identified as Alannah Brown and her boyfriend, Douglas Barker, whose deaths shocked the local community and prompted an extensive police inquiry.
Recent Arrest and Charges
Grenier was arrested on Friday and remains in custody following the announcement of charges on Saturday. This arrest represents what authorities describe as the "final anticipated arrest" in this investigation, bringing some closure to a case that has involved multiple suspects over several years.
Previous Charges in the Case
This case has seen previous developments with three other individuals charged in July 2025:
- Jilane King was charged with first-degree murder of Douglas Barker and being an accessory after the fact to the killings of both Barker and Brown.
- Simon Bourbonnais faced multiple charges including accessory after the fact for both killings, unlawful confinement of Alannah Brown, indignity to human remains for both victims, and manslaughter of Brown.
- Tyler Stuart was charged with accessory after the fact to the murders of both victims and indignity to human remains.
Additionally, another person was arrested in November in connection with the investigation, though specific charges for that individual were not detailed in the recent announcement.
Police Statement on the Investigation
B.C. RCMP Superintendent Sanjaya Wijayakoon addressed the media on Saturday, stating: "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 statement underscores the challenging nature of the investigation while expressing sympathy for the victims' families who have endured nearly four years of uncertainty since the tragic discovery in 2022.
The case now moves forward through the judicial system as the accused face formal legal proceedings for their alleged roles in the deaths of Douglas Barker and Alannah Brown.
