TS,
见好就收 
The police already mentioned they wish to take this as a civil case .... i reckon you go draft a settlement agreement ...... including her compensation and the damage of the carmera (which i think she would not bother)
Both signed with a witness .... and whoever pay to who i dont care but close the case so that you can move on
Honestly, you are quite an asshole to post an ad to get free models and free sex ... those girls who came and gave you what you've planned, are no fool as well ... as they thought by doing so ... they are gambling for future fame ... or purely for fun
In my opinion, the above is already a fair deal, you gave an invitation to treat and they came with acceptance without an offer in the first place ......... However for that FL to try her luck .... your one sided story may not have mentioned that she did hinted to you ... that you needed to pay her for the sex .... god knows.
Neverthelss, most important, TS learn something from this chapter of your life. Go clean from now on with some proper documentation
