This stuff happens a lot with elderly people with some money, and diminished faculties.
Friend of mine’s grandmother wired several hundred thousand dollars to what is believed to be scammers (nobody knows how they got in contact or what they said). She also sold her newish truck to the neighbors for $100.
My friend’s mom’s half siblings managed to talk her into cutting the mom out of the will - - even though they are wealthy. The mom had about 100k bilked out of her by her shitty other daughter and son in law. (Trump supporters and “good Christians”)
