You just made your best argument in your reply. I would add to that argument that at the time she was given the perfect opportunity to observe what you where removing and that you removed nothing of hers.
You are right that she will have to prove the items where taken by you. If you show up at least and make the above argument then she has to have proof (photographic, possible testimony form someone saying they have seen the items in your possession.) If she has no proof she looses. If you do not show up for the hearing she will not have to prove anything, she wins automatically.
