Wow...he sounds like a playground bully...taunting you like only a bully would. What a jerk! (I could think of other words, but I don't want to stoop to his level.)
I'm happy that her attorney has dropped her case because of his antics. I'm sure there's more to it than that. Certainly, Attorney Mera could have dismissed this jerk from being her assistant due to his childish (and threatening) behavior.
I also wondered, while reading his emails, if there isn't a 'relationship' between the abductor of him? I hope you do file a harassment suit against him...he needs to be "shut up" in his own country. He's a disgrace to the legal community in the DR, even if he's not an attorney (but working with one).
