It’s not entirely clear whether or not he’s running a business in Ohio any more. If you follow the links to the cleveland.com article, the current owners of Cleveland Plating had been trying to get a restraining order against him. He’d already broken in and put locks on all the doors, and assaulted an employee in another incident.
It looks like he owned the property and had run a business out of that location at one point, but was obviously feuding with Cleveland Plating over the lease–clearly in a constructive and healthy fashion.
The drilling episode gets better; two of the tanks he drilled into contained sodium cyanide and hydrochloric acid. Considering one of the products of that reaction is hydrogen cyanide gas, it’s a wonder he didn’t kill somebody, and I’m sure that cost the current owners a pretty penny to clean up.
