An Edmonton man has lost an appeal of his conviction for murdering his pregnant wife.

Three appeal judges were unanimous in turning down White's multi-pronged appeal. His appeal was centered on whether the trial judge should have instructed the jury on his post offence conduct.

Police watched White's actions after his pregnant wife went missing in the summer of 2005. They observed White as he retrieved garbage bags from a nearby field that were filled with bloody clothes.

The appeal argued that jurors should not have considered these actions when they deliberated on whether White committed murder. The appeal also questioned whether the judge should have instructed jurors on how to consider White's previous criminal record.

White's lawyer, told CTV Thursday that his client is disappointed.

White, a heavy-duty mechanic and former soldier, was convicted in 2006 by a jury of killing Liana White and dumping her naked body in a ditch.

Testimony at his trial indicated that White tossed bloody evidence into a garbage bag which he left in a field and returned later to pick up.

White testified he never killed his wife and said blood in the home came from her having a nosebleed.
