So the story here is that this friend of yours send, at some point, nude pics (some of them when she was minor...) to a guy that he is now dead.
Then all of a sudden, she receives a mail (?) or a FB message (?) to send to this account more pics or else the blackmailer will post the pics that he has already to her job, friends etc surroundings. Am I say it correctly or I miss something?

Sorry to ask again but some details can make a big difference.
