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 found dead 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.Nisman's death was initially ruled a suicide by a group of forensic experts appointed by Argentina's Supreme Court in 2015.
However, in 2018, Nisman's death was determined to have been a homicide by a forensic group of the Gendarmerie.
Cristina Fernández de Kirchner was accused of being the prime suspect in Nisman's homicide, and is currently being prosecuted on conspiracy to commit murder charges by a federal judge.
