Closing arguments are expected to begin Thursday morning in the trial of a man accused of first-degree murder in the death of a Saskatoon woman.

Douglas Hales is charged with strangling and savagely beating Daleen Bosse, whom he had met at a bar where he worked as a bouncer. Bosse disappeared in 2004 but her burned body was not discovered until four years later.

On Wednesday, Hales testified that contradictions in his statements are the result of the tremendous psychological pressure he was under.

He was arrested after a so-called Mr. Big sting, in which undercover RCMP officers posed as members of a criminal organization trying to recruit Hales.
