Sounds like AI is just greasing the wheels of a long established 'grandparent scam'... goes something like this:
1) voice one: young adult calls, sobbing 2) grandparent inquires with a name... "Ben, is that you?" 3) voice one: "Yes grandma, it's me, Ben... I'm in trouble, please don't tell mom 4) voice two: "Hello, I'm attorney..."
My grandmother fell victim to this almost 20 years ago, which only stopped when Western Union refused to let her continue sending wires... she was forced to call her daughter (at which point they just called my brother.)
Our takeaway (at the time)... the voice doesn't even need to be terribly accurate, since the original interaction is brief / somewhat inaudible over the tears. Typically just requires an older vulnerable adult, a lucky strike with the initial setup (e.g. grandparent actually has a grandkid), and a lot of high pressure / duress salesmanship.
