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

Michael 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.

His lawyer argued before the Appeal Court that the trial judge erred when she asked jurors to consider White's conduct after his wife's death in July 2005.

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.

The Appeal Court ruled that the judge did not err in any of her instructions to the jury.
