A judge can't see through anything as they think logically and are not swayed by gut feelings like a jury may be. Put it this way, there is only one way to prove that she had prior knowledge of what was in that trailer and toolbox, that is if Dellen Millard testifies that he told her as much. Will he? Not likely in my opinion based on the fact that he's still got two more murder trials in front of him and he'll want to keep what he says and admits to to a minimum. But who knows, spite for keeping those letters? Millard's attorney insinuated about a "you testify against him, he'll testify against you" arrangement, so who knows? But would anybody believe what Millard says at this point?
