That is my question as well and why I think he State should have filed a Motion in Limine to block arguing such a theory without experts who would provide the necessary link between being molested as a child and being unable to either (1) report the death of your child or (2) grieve over the death of your child.
Is it possible that the defense is just now trying to get their expert in?
On 5/26 Baez was asking JP to sign a motion for approval for the transcripts of Dr. Krop. On 5/27 the defense filed a Supplemental Defense Witness List, which (I believe) we haven't seen yet.
Generally, the attorney who is most likely to elicit an adverse reaction from a witness should be the one to cross examine the witness.
Casey has specifically expressed her dislike for Ashton.
Also, Linda is a very methodical questioner, meaning it would be easier for Casey to maintain a consistency and time continuum with Linda's style of questioning. On the other hand, Jeff is better at examining without a scrit if you will and is more comfortable being argumentative with witnesses, whereas Linda maintains her composure and level.
