I think the girls Birth certificates may have been why they would have wanted into the safe. Also I agree they may have wanted to place those fake notarized guardianship papers in the safe to make it appear as though Hannah signed them and put them in the safe herself for safekeeping.

I do have Russian nesting eggs brought by a client who worked in Russia. He also brought me eggs from Ukraine and a Faberge from Russia. BTW the Russian eggs are almost all wooden and are painted like Easter eggs. Six eggs in all. I have some from China, Japan, Taiwan, Brazil, Puerto Rico, Guam and other countries courtesy of clients who worked there. I have them from Jamaica, Bahamas, and other islands from cruises.
