I think he will cross examine her about the abduction and murder ... he is one of the best around apparently, The defence's case seems to be welll thought out ... they are going in a logical order, establishing her history and character and showing evidence to back up their defence strategy. If he can poke sufficient holes in her story under cross-examination, her credibility will be compromised, leaving a larger window of opportunity for the jury to see MR at the very least as the more sympathetic of the pair. Having said that tho the forensic evidence has not yet been presented, and from what we know so far, it wil be difficult to refute. There is still a long ways to go in this trial.
