Yes, it can be checked whether he had them, and if he did indeed lose them, I would like for them to be returned. But as of now, I do not trust this person. If I ever wanted too, I could probably gather up 20 of my friends and have them all tell the Staff the same story about how I lost items I never had.

It'd go something like this:
Well, I was in the trade tables, and I was showing these items to my friends. Suddenly, my ISP crashed, and I couldn't get back online for 15 minutes! By the time I returned, my items were GONE! My friends told me that som, guy ran in and claimed ownership of the table when I signed off and he took all my items! I have evidence and witnesses! Give me back my items!

A staff, faced with 20 witnesses usually wouldn't bother doing the long and tedious task of sifting through logs, and instead grant him these items.

My thought is simply that despite that this guy claims to have 20 witnesses, I suggest that the staff still go through the logs before returning these items that may or may not have ever been in his hands.
