Appeal – Sentencing – Evidence – Whether Court of Appeal erred in materially altering and reinterpreting the facts set out in the Agreed Statement of Facts put before the trial Judge at sentencing

On the morning of March 3, 2005, on a farm near Mayerthorpe, Alberta, James Michael Roszko ambushed and murdered four RCMP Constables and then killed himself. Although not on the farm at the time of the shootings, the applicant pleaded guilty to manslaughter as a party to the murders. Sentencing was based on an Agreed Statement of Facts. At issue is the fitness of the applicant’s sentence. According to the Agreed Statement of Facts, the applicant had been “involved” in a marijuana grow operation that was located in a Quonset on Roszko’s farm. At the time of the shooting, the Quonset was under police control and being investigated. Roszko fled the farm the day before when a bailiff who had arrived to seize a vehicle called police for assistance. Roszko had returned to the farm overnight with a plan to burn down the Quonset in order to destroy evidence of the grow operation. The applicant was accused of assisting Roszko in his preparations. The applicant gave Roszko a rifle and ammunition. The Court of Appeal held that, because he was involved in the grow operation, the applicant was motivated to assist Roszko to burn down the grow operation in order to destroy evidence. The Court of Appeal inferred from the Agreed Statement of Facts that, in the hours preceding the shoot out, the applicant helped Roszko commit the crimes of vehicle theft, arson and obstruction of justice by accompanying Roszko in his own vehicle while Roszko hid the sought-after vehicle from authorities, driving Roszko to a road nearby his farm, dropping Roszko off so he could return to the farm armed and on foot, and failing to warn the police.
