Anita Weinstein was on the second floor of a Jewish community center in Buenos Aires on July 18, 1994, when the ceiling and walls collapsed from the force of a truck bomb outside.

Disoriented, and terrified by the screaming and sudden darkness, she still managed to climb down through the rubble and call her daughter to tell her she was OK.

The emotions of that day came rushing back two weeks ago, when her daughter called with news that Alberto Nisman, the prosecutor investigating the bombing at the Argentine Israelite Mutual Association (AMIA), had been found dead with a bullet to the head in his Buenos Aires apartment.
