The Saskatoon man on trial for first-degree murder in the 2011 death of his wife took the stand Monday to say he is innocent.

When David Woods was asked if he had anything to do with the death or disappearance of Dorothy Woods his answer was "no, I did not.”

Dorothy Woods was last seen in November 2011 and her body was found almost two months later south of Saskatoon in a frozen culvert near Blackstrap Lake.

David Woods testified a note was left on his windshield while he was out for lunch in January 2012. It had directions to a location south on Highway 11 and mentioned Dorothy. Woods said he was curious so he travelled the route but didn't see anything. This was the trip where police investigators tracked Wood’s vehicle via GPS and which the jury and court participants travelled last week.

Woods talked about what he did on the days surrounding Dorothy's disappearance and testified he never thought she was missing -- just that she had run off.

He did say he gave inaccurate information to police. On Monday, he testified that he had locked his wife's credit cards away due to overspending and that he threw her makeup bag in the garbage when he was upset and found it in her truck.

Woods also testified that in the spring of 2011 he and Dorothy decided to have an open relationship. Their agreement was to keep the arrangement private so their children and family didn’t find out. He admitted he saw prostitutes.

Earlier Monday an expert on tape and adhesive told court that tape found on Dorothy's body matched a roll of tape found in Woods' garage and that the ends of both pieces fit together like a puzzle.

The Crown’s cross examination of David Woods was expected to begin Tuesday morning.
