Thank you for the further information.
That's too bad. If you had obtained an Order of Protection against her while she was within the jurisdiction of the US, you could then take this order to Switzerland and have it enforced against her immediately.
Unfortunately, the fact that she is in Switzerland prohibits you from being able to get a criminal order of protection against her from the police (which would be free for you). Thus, your current options are:
1. Because this woman has threatened to physically harm you and has actually damaged your property, this violates Swiss law. You may contact the Swiss police in the town where she lives and report the crime and ask for a restraining order there for further protection. You would be best served by contacting a Swiss licensed attorney (there are many American law firms with offices in Zurich or in Geneva with licensed Swiss attorneys) who can make contact with the police to report this on your behalf. It is much more likely that the Swiss police will take action if you use a local attorney to report the harassment
than if you attempt to report the matter yourself (not to mention the probable language barrier problem).
2. Further, because she was here when she caused the physical damage and has apparently defamed you, you could sue her in a Illinois court and assert "long-arm" jurisdiction over her for trespass to your property, for assault based on the threats of physical violence, and for defamation
for contacting your clients. You could request along with this lawsuit a civil restraining order (permanent injunction) barring her from contacting you and your parents by phone or from coming within a certain distance of you. Once you get a judgment from the courts in Illinois, you can take this judgment and ask the Swiss courts to enforce it for you. There are several treaties between Switzerland and the US wherein the courts will respect foreign judgments. Again, this would need to be handled by a Swiss attorney.
