Assume that you have bought a house that you are going to make into a rental property.  Some demolition is involved to remodel the kitchen.  During the demo phase, the old cabinets are knocked out by the construction crew.  A false wall is uncovered.  Inside the hidden chamber a construction worker finds $20,000 in cash.  The money is dated approximately 50 years ago.  The house has sold seven times since the 1970's.  To whom does the $20,000 belong?
