An appeal by Douglas Hales of his murder conviction in the death of Daleen Bosse has been dismissed by the Saskatchewan Court of Appeal in Regina. Hales was found guilty of strangling Bosse and burning her body near Martensville in 2004. Last December, he was sentenced to life in prison with no chance of parole for 15 years. The move to appeal Hales’ conviction was based on a Supreme Court judge ruling that a “Mr. Big” sting operation, in which officers†pose as low-level criminals to get information, was inadmissible. However, the three appeal court judges said evidence against Hales was overwhelming and not solely due to the “Mr. Big” sting. Hales led undercover officers to Bosse’s body in a stand of trees north of Saskatoon in 2008.
