This absolutely was not mentioned in the agreed statement of facts. It was stated out of court by Noudga's lawyer that everyone acknowledged she did not know.
Nothing of the sort was said or even hinted at by the prosecution. What Craig Fraser said was he believed the Crown had a strong circumstantial case but there was no direct evidence Noudga knew.
The judge, in a declaration that left many jaws on the floor, announced he would not have been able to find NOudga guilty beyond a reasonable doubt. The Crown attorneys declined to comment on the pronouncement.
People are completely free to disagree on what Noudga did or didn't know.
From the National Post
"In an eight-page agreed statement of facts read aloud in court by Assistant Crown Attorney Brett Moodie, Noudga admitted she helped move, destroy and hide evidence relevant to the police investigation into Bosmas murder, but without knowing of the murder."
