UPDATE: Squatter is gone, and building is demolished!
I know that I have not heard the last of this man, he will probably try to raise some hell when he gets out of jail. However this does not concern me as long as my project can go uninterrupted now.
To answer everyones dying question, there was a 5 gallon bucket in the corner for him to do his business in. Also there was several kerosene heaters in there and the ceilings were black as a result. The extension cord running into the building had about 5 surge protectors plugged into it powering different lights and 4 TV's.
Some other interesting things found: massive amounts of porn, jui jitsu trophies, stacks of law books and everyones favorite "Rich dad poor dad" collection of books. Oh and also an Armando Montelongo dvd (no dvd player anywhere?) so that proves he was definitely a real estate guru. Also found a metric ton of papers regarding past and present lawsuits.
To top it all off, the mans brother and father came over when I was demo'ing the building and were nice as pie.
Thank you everyone for your support and words of encouragement. This site is truly amazing in bringing all of these likeminded people together to solve problems.
