Ok, after having scoured declassified documents with a possible list, I think that we can narrow down to a few possible folks.
The problem is that we don't have the full names and the spelling mistakes, which hampers any research.
- EMILIO & CARMEN DE IPOLA: The only Emilio de Ipola I found is on Facebook, his last public message was in Feb 2018. I haven't found any comprobating data about him nor about his wife.
My problem is that "De Ipola" gives me plenty of homonyms, so without any other names, I am hampered in this search.
- JULIA KLENK: I haven't found any corroborative element and it's quite a widespread name in German speaking countries. The fact that she has a German name doesn't prevent her from being of South American country.
But without age in 1976, no other background information, I am left without any solid clue.
I need a German speaker for digging into the Court cases about Argentina in Germany, as my knowledge of German amounts to zero.
- Antonio Misetich: okay, this case is particularly iffy. Scoring the database "desaparecidos.org", I haven't found him.
His employment history is unknown per the link. However, Argentina confirmed that he was detained in April 1976 to the IAHRC, but in November 1976, Argentina said that he was not registered:
Human Rights and the Phenomenon of Disappearances
Found a declassified document in 2019 about him:
The National Security Archive
He is a disappeared, but AFAIK, the US was not exactly known to bring disappeared in the US to kill them. They were killed in Argentina.
And yes, the US did kill disappeared:
Inside Argentina’s Killing Machine: U.S. Intelligence Documents Record Gruesome Human Rights Crimes of 1976-1983 | National Security Archive
I can not find a photo of him.
His case is very iffy. No independent finding to corroborate the fact that he is a disappeared, shape or form. I'm waiting for Abuelas de Plaza de Mayo's reply to shed the light.
- Luis Itarruga Casali: released in December 1976 per this cable dated 1977
Cable: 1977BUENOS05592_c (I know, Wikileaks. But I haven't found anything else so far)
He is absent in the list:
Presentes en Argentina: Muro de la Memoria
As he was released in December 1976, he was detained when our JD were found.
I haven't found any corroborative data to support his actual release.
- RICARDO ALBERTO HINRICHSEN: His name is so common in Latin America that I haven't found any corroborating data.
He is absent of the website "Desaparecidos.org" and I haven't found any element supporting his expulsion.
Per this cable
Cable: 1977BUENOS05592_c he has been deported. However, I haven't found independent data to corroborate this information.
I can't trust the declassified documents to corroborate a deportation, as the CONADEP found that the Argentina regime falsified documents to make believe that the disappeared has left the country when it's not true. So, for this person, I can't rule in nor rule out because of no independent corroborating data.
- MANUELA ELMINA SANTUCHO: She is said "Under review". Another cable about her:
The National Security Archive
She is a disappeared, but I have no independent data to support the fact that she is actually a disappeared.
- DR. MARIO SCHRAIER: I have found nothing beyond the cable I am scouring. Something I didn't expect, as because being called "Doctor" in Argentina in those days means that you are highly educated and hold a respectable position.
So, I have no element to rule him out, but unlikely him.
Possible spelling mistake? I'll revisit him today to be sure that I haven't missed anything.
- MARIA PEREZ BRAVO:
I found a Cuban homonyme, which can't be disappeared from Argentina Marta María Pérez Bravo - Wikipedia
The Cuban artist can not be our lady because she is alive.
You have to completely disregard the Cuban artist, she has not been involved in Argentina or Condor operation, shape or form.
The person told in the cable is another person whom I have not found a thing linked to Argentina, Uruguay, Chile or any country linked to Argentina Dirty War AFAIK. It needs a deeper digging to know the truth.
- GERARDO BATTI ATUNA: except this cable, I found absolutely nothing about him. He is nowhere listed as a disappeared.
I suspect homonyms and/or spelling mistake by the US services.
- RAIMUNDO NACHUMOW: found homonyms, so I am not sure about him at all.
I found possible elements making it possible to be him, but I can not display them unless and until I have more probative evidence.
It makes a shorter list, but more complicated to rule them in or out.
