She says that the guy she originally sent the pics to a long time ago is dead, died, and has been dead for quite a while now..
I also think it is someone that knows her, because he is trying to blackmail her for more pics/vids, which is weird to me.. He isn't asking for any kind of payment like $$ or BTC, but more pics..
Creepy AF..
This is a job for the authorities, especially since some of the photos are of her as a minor. The person in possession of the photos is very likely related to the dead guy, it shouldn't be hard for the cops to track down who ever it was that took possession of his electronic devices.
