The accused 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.

Charges have not been laid in connection with 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 began six weeks ago. A verdict is expected sometime in early December.
