What is the most bizarre case you have ever inspected?

"The most bizarre case I have ever inspected was an apartment building that had a new sprinkler system put in. The building inspector called me to assist with the inspection of the system before the occupants could return. While inspecting one of the apartments, I heard a noise coming from behind a cabinet in the kitchen. It was strange because all of the occupants were out of the building. I opened the cupboard and saw a piece of wood that looked like it had been cut out of the back of the cabinet but wasn't placed in the hole correctly. I pulled the wood out and saw a face staring back at me. Apparently, there was a secret room behind the cupboard where a person was living. She had access from outside of the building and used the hole in the cupboard to enter the occupant's kitchen and eat their food."
