Friends had called police, etc and had taken care of the body and the animals... so far, so good.  

@Mitchell Frisby just go forward with the eviction process and inform them that you will do everything within your power to collect on any damages to the property as well as press criminal charges for vandalism if they intentionally destroy your property (unlikely that will go anywhere unless you have solid proof they did it, and can get the police to do anything about it, but they don’t know that).

A police officer once said; "People love to tell their story".

Don't cause trouble for me, the neighbors, or the police.

In my market, without this notice posted on all four corners of the property, police will not remove/charge any person from the property.3. 

The daughter tried to threaten me with police because her idiot parents misread my email wrong to send the application to...then she tried to change her story when I explained things to her and her excuses with apologies made no sense.

I am not interested in policing that type of activity. 

The last thing you want is for the police to conduct a drug bust.

And, if his customers are sketchy, there could be issues with them, too.And would your insurance cover damage caused by it.I'm assuming it's legal, but prior to it being legal here, the power company would tip off the police if a place started using lots of electricity, then you have the police showing up, too.And, don't remember if someone else mentioned this, but is it legal to run a business out of your property? 

Your city may require you to attend a Crime Free/Drug Free class to be certified, this is a good class and get set up and take it, call your police department where the property is located and find out more.Apartment buildings are sold everyday, Some with 100's of current tenants with leases that are transferred so your not assuming something that other landlords haven't done and will continue to do.
