Finger Prints?
KEILFRANK:
"Where all this will go?" depends entirely on how far you and your girlfriend are willing to take this matter!
For the ex-tenant's trash talking and what not, you can either consider the whole thing to be just a storm in a tea cup, put it down to experience and move on with your lives, or you can get litigious and spend thousands of dollars prosecuting a slander suit which will have you in and out of court rooms from anywhere between 12 to 24 months.
And while you may have cause to pursue a slander suit, you have absolutely no cause to pursue the ex-tenant for burglary. None whatsoever, and I am amazed that the police have taken your complaint as far as they have, even crossing into the ridiculousness by dusting the place for prints. Of course the place is going to be plastered all over with the tenant's prints; she lived there after all.
It is a legal impossibility to charge someone with burglary for breaking into her own place in order to steal her own personal belonging. Because until a judge issues an order setting the time and the place for the eviction, and until that time has come to pass, the place is still hers and she can come and go as she pleases. In fact, you may well find yourself in some hot water for entering the rental unit before eviction is complete. So, save yourselves a lot of unnecessary headache and wait until after the upcoming hearing to enter the property.
As for the slander; well, from what you have said, your girlfriend's loss of income, which if as you say was directly due to the tenant's online rambling and other acts of character assassination is very much actionable. Because gone are the days when slander actions where commenced and insanely maintained for simply having feelings of hurt and embarrassment. Now days, it is not enough just to say so-and-so slandered me, because in order to recover, a plaintiff has to show actual damages suffered as the result of the slander.
That said keep in mind the neutralizing factor in this equation which is: truth is an absolute defence to a charge of slander. Meaning that even though your girlfriend lost contracts because of something the tenant said about her on line, she cannot recover if what was said is the truth and was not a made up story.
If shutting her up (the tenant) is your primary concern, you may want to take out a restraining order against her and see if that works.
