CALGARY – A man and woman charged in connection with an ongoing 2017 quadruple homicide case are set to face a Calgary jury Monday morning.

Yu Chieh Liao, who goes by Diana Liao, and Tewidris Kebede are charged with first-degree murder in the death of Hanock Afowerk. The body of the 26-year-old was discovered in a ditch near Highway 8 and Highway 22 on July 12, 2017.

Two days earlier, the bodies of 36-year-old Glynnis Fox, 39-year-old Tiffany Ear and 25-year-old Cody Pfeiffer were found in a torched vehicle at a construction site in the northwest community of Sage Hill.

The accused, who are both 27-years-old, were arrested in Toronto on unrelated matters.

Liao also faces three counts of accessory after the fact to murder. Kebede is charged with one count of accessory after the fact for the death of Pfeiffer.

Fox and Ear were sisters from the Stoney Nakoda First Nation, who left behind 16 children between them.

Homicide charges have not been laid for the deaths of the three victims found in the vehicle. Calgary Police Service officials confirm to CTV the homicide investigation is still open and police will follow any new leads. 

The jury trial is scheduled to last six weeks.
