Sandra Arroyo Salgado has become the keeper of the flame for her ex-husband, the late Argentinean prosecutor Alberto Nisman. Chief investigator of the 1994 bombing of the AMIA Jewish community center, which killed 85 people, Nisman fingered Iran as the culprit and accused then-President Christina Kirchner and Foreign Minister Héctor Timerman of colluding with the Islamic republic.
The night before he was due to testify before congress on the matter, Nisman was found shot to death in his apartment. The incident was almost instantly ruled a suicide, which nearly no one believed, and it is now widely assumed that he was murdered. By who remains an open question.
Arroyo Salgado, herself a federal judge, has led something of a one-woman campaign to find the answer. She continues to insist in both domestic and foreign media that her ex-husband was murdered and the Argentinean government is covering up the crime. In 2017, she went so far as to meet with the pope, who expressed support for her efforts. (Photo credit: YouTube screenshot.)
