I had a rental house in Kansas City come vacant in January and hired a handyman ..in process of trying to become a contractor (he had recently formed an LLC company)... to replace some tiles and paint...simple job and nothing complicated. He came highly recommended as he had done good work for a couple people I respect & I had used him on smaller fixes and no problems. He also used to work at a large respected property mngt company that manages 1000 properties.

My job was suppose to be done end of February and we kept giving him extensions until finally we got super fed up & gave him a hard deadline of last week. We told him we'd pay him for whatever he could finish by then but he was off the job...fired basically. The work he did was extremely poor quality and mostly having to be redone. I suspect he might have fallen into hard drug use based on the work quality of what I saw & what the neighbors told me they saw of him when he did show up in the middle of the night. I did pay him partial payment and withheld funds to fix what wasn't done or done poorly...more than fair.  Although he let it be known that he thought he had done a perfect job & was completely delusional about it. 

I noticed the basement drain backing up on his final day after he had just left (and before he knew what he was going to get paid) but just thought it was the drain clogged and yesterday when my plumber came out he found there were rocks and cement that had been flushed down the sewage pipes which was causing the sewage to back up in the basement. There is even cement that was poured down the tub drain and cement over the drain in the basement..every plumbing hole he could find he poured cement in. My plumber said whoever did this spent a lot of time flushing rocks and he estimated about 80 pounds of cement down the sewer. He said it had to have been flushed down the toilet to get that far in the pipes & it was a crap ton of cement and whoever did it took A LOT of time to get that much rocks and cement down the pipes. I called the police and they told me that because I don't have him on video and no one saw him do it and because he had legal permission to be in the house working on it when this was done there was nothing they could do. They wouldn't even do a report. 

 No one else but him had keys/access to the house so clearly it was him or someone he brought in to work with but can't imagine why anyone but him would have a motive to do this & go to this much trouble. I feel he did it to get back at me for firing him. 

I am also afraid of what he is capable of doing if I publicly go after him too hard seeing how crazy he is but at the same time he's going to be out there possibly working for other investors or property management companies or homeowners etc and is a dangerous & super vindictive psychotic person. 

I am interested to hear what advice you guys have for me as I'm not sure what my next step to be. Feel free to PM me as well.
