EDSON, Alta. - An Alberta man faces a manslaughter charge after police allege he supplied pills in a carfentanil overdose.

RCMP say 48-year-old Guy Kennedy was found dead in a hotel room in Edson, Alta., on Oct. 21, 2016.

Police say several tablets and powder residue were in the room, and tests later confirmed the tablets were counterfeit OxyContin and contained carfentanil.

In March, the Office of the Chief Medical Examiner in Edmonton determined that a carfentanil overdose caused Kennedy's death.

Shawn Taras Prokopchuk, who is 32 and from Calgary, faces a charge of manslaughter and trafficking.

He was arrested last week and is to appear Tuesday in provincial court in Whitecourt.
