Is she in ND or AK? Were all of the knives shipped to the same address? Assuming the answer is "yes," I recommend calling LE in that jurisdiction. If y'all want the effort to be effective, I suggest getting in touch with each other, compiling the individual circumstances into a single document that identifies each victim, their contact info, exactly what they've lost, some reasonable demonstration of the how the values were established (not everyone, including LE, understands how expensive some knives can be), and send one document to the Sheriff's office (after a preceding phone call). You need to make their job as easy as possible.
