Natalio Alberto Nisman (5 December 1963 – 18 January 2015) was an Argentine lawyer who worked as a federal prosecutor, noted for being the chief investigator of the 1994 car bombing of the Jewish center in Buenos Aires, which killed 85 people, the worst terrorist attack in Argentina's history. On 18 January 2015, Nisman was murdered at his home in Buenos Aires, one day before he was scheduled to report on his findings, with supposedly incriminating evidence against high-ranking officials of the then-current Argentinian government including former president Cristina Fernández de Kirchner.
