Edmonton Police Charge Partner With Second-Degree Murder in Marika Sutton Case

Police say they delayed public notice to protect the investigation.

Edmonton police have charged a man with the killing of Marika Sutton, 29. Pictured is the vehicle that police believe the accused was driving when her remains were likely disposed of along Highway 2 between Wetaskiwin and Lacombe.
Marika Sutton was last seen in early August in the Richfield neighbourhood in Mill Woods, according to a news release from Edmonton Police Service.

Overview

  • Edmonton police said Friday they charged John Angus Joseph MacArthur, 47, with second-degree murder and indignity to a body in the death of Marika “Mika” Sutton.
  • MacArthur was arrested in South Melville, Prince Edward Island, on March 17 and transported to Edmonton on March 20, where he has been remanded.
  • Investigators classify the case as an intimate-partner homicide after finding a history of domestic violence in the relationship that had not been reported to police.
  • Sutton’s remains have not been found, and detectives believe they were left between Aug. 22 and Aug. 29, 2025, along Highway 2 between Wetaskiwin and Lacombe.
  • Police are asking anyone who saw a 2014 black Jeep Patriot with Alberta plate CFB 2578 in that corridor, including landowners and hunters, to contact investigators.
