Wow, very sick. An easy prey indeed would be older people. perhaps with memory problems, feeling alone and intimidated.
It reminds me of another scam where they send COD some piece of junk that the newly-deceased spouse supposedly ordered just days before death.... what will the grieving and confused spouse do? Pay the imposter....
Yes and its even worse when you don't know your rights. You have someone threatening you if you don't do something now and people do stupid things like dig into their 401k or borrow money from relatives to pay what amounts to a conman or conwoman.
