I think I read where you are going with this Mysterylover. Now, I am no conspiracy theorist, and I really don't want to open any can of worms on what is surely a very sensitive subject for those family members of the disappeared who are still alive. Specifically, Maria's Mother and brother whom it seems are directly involved with the Mothers of the Plaza de Mayo.(

It is my understanding that the circumstances of Argentina's Dirty War (
http://en.wikipedia.org/wiki/Dirty_war) are still sensitive. Even though both the U.S. and Argentina have declassified documents relating to the disappearances and other activities, I am not sure how far I want to take this train of thought.
That said, some interesting information that I scoured up last night from various websites;
-Cesar was a Dr. of Veterinary Medicine
-Maria's Father was a diplomat who tried to have her released
-Speech given by Maria's mother to Human Rights Council(
http://www.ngocongo.org/files/ngo_speaker_hls__marta_vasquez_eng.pdf), she seems like an incredible woman who has devoted her life to protecting the rights of others, I would hate for her to have to go through the kind of pain she suffered again, if there is any validity to this connection, and even if there is none.
-Declassified docs (

I can see this as being a very difficult avenue to follow that will be met with much resistance because the circumstances are almost beyond belief, and would raise many uncomfotable questions for all parties. I would hate for this to bring any further pain to those involved.
