Derstine won't be trying to prove his theory, but putting holes into the Crown accusations by way of another possible scenario.
I agree that Derstine made his inroads during the cross examinations.
He destroyed TLM's credibility with the revelations of the letters, music, and statements to her godmother. The jury now has to decide to believe all or any of TLM's testimony.
He forced the pathologist and forensics expert to admit there was no scientific proof of a sexual assault.
In addition to those cross examinations, Derstine presented a witness that raised questions with TLM's statements on how she abducted VS, and that there was no evidence of nefarious content on MR's Blackberry.
The Crown and defense now have the job of tying it up all for the jury to ponder during deliberations.
We will see how that goes.
