The thing i see here is you don’t have to know if it’s a crime to report it. If you believe a crime has taken place, you are free to contact any authorities you believe would be appropriate and make a report. You can contact any or all of the possible agencies having authority to investigate and seek prosecution. If they don’t see it as criminal activity, they may tell you so or simply accept your report and take no further action. Often times the victim believes they have to know what specific crime has taken place. It is never the victims place to make that determination. That is up to the entity filing charges (prosecuting attorney or more often referred to as the prosecutor, the district attorney (DA), states attorney, or several other titles that mean roughly the same position).
So, if you believe a crime was committed, make some calls to the local and/or the state police where the suspected offender lives. As well you can file a complaint at the link I provided. If any of them see a crime involved, they will take it from there.
