Contact the police and arrange for her to set an appointment to meet with the (possible) scammer and have a cop there to grill and possibly arrest the (possible) offender. Or verify that she's valid.
Our police department here is worthless, probably not by the fault of individual officers, but because of the top brass and the leftist government which directs them.
Even in my relatively conservative large Texas city, the “defund” movement has made inroads. Our police chief bowed before BLM madness two years ago. The officers are spread thin and have to cut corners. I’ve made calls for service and waited hours, or was never contacted at all. A lawn maintenance acquaintance of mine was robbed at a convenience store gas pump by three “Amish” thugs who hit him over the head and stole money and a GUN, and police never responded to his call - at all.
We are living in the beginnings of anarchy.
