You are correct in that these items should not have been removed unless otherwise agreed to in writing. I would be surprised if the Bank or any of their reps. were involved. It very well could have been the former owners who came back and gained entry with an old key. Either way, I would file a Police report and notihfy your Broker & Agent. Have them notify the Listing Agent that you did not receive possession of the home as agreed to in writing. The Listing Agent should be able to pick up a report from the local Board of Realtors which will list all individuals who gained acces to the home via the Supra lock box during this period the items were removed. The only exception to this will be if the lock box was a combination lock box. You should also consult a licensed Attorney that specializes in real estate law if you feel your best interests are not being protected. Lastly, make sure you change all the locks to the home. Best of luck!
