Friend of mine from Bari had the same problem with their old grandma. She (my friend, not the grandma) showed up with a bunch of male friends and told the fake caretaker "Leave by the door or you'll be leaving by the window, either way do not come back". The scammer left by the door and that was the end of it. The grandma died 18 months later in her bed surrounded by her family.
