Three men found guilty of first-degree murder in the beating death of Shawn Douglas are appealing their convictions and sentences.

Dennis Thompson, Joshua Wilson and Jonathan Peepeetch were sentenced to life in prison with no chance of parole for 25 years in the August 2014 death of Douglas.

Thompson and Wilson say in their appeals that the trial judge allowed prejudicial evidence and erred in her instructions to the jury.

Peepeetch claims in his appeal that he wasn’t properly represented by his lawyer, and that the prosecution used unfair tactics. He also says there was a lack of evidence to support a conviction.

The trial heard that Douglas was forced into the trunk of a vehicle and driven to a wooded area northeast of Regina, where he was beaten with weapons, including crowbars and a sledgehammer.
