Lost & found briefcases in Bismarck

Found black leather briefcase with important documents at Bismarck mall parking lot near a blue minivan.

I found a black leather briefcase at the Bismarck mall parking lot near a blue minivan around 3 PM on Saturday. It looks like a nice, professionally used one and has a few important-looking documents inside which might help in identifying the owner. If this is yours, please describe the contents or any unique features to verify ownership.
