Conspiracy theories abound when Alberto Nisman is found dead, hours before he planned to present the results of his investigation into the AMIA bombing.

Special prosecutor Viviana Fein discusses investigating the crime scene. Experts debate contradictory evidence and ask: Was Nisman's death suicide or murder?

It seems clear that the death of Albert Nisman is connected to the AMIA bombing 10 years previously. Links between Iran, Hezbollah and the AMIA bombing are investigated and Jaime Stiuoso, ex-director of the intelligence service, discusses his partnership with Nisman.

Nisman's ex-wife and others reveal events that occurred in the days before his death, including his accusation against Cristina Fernández de Kirchner.

As unrest over Nisman's death grows, Prosecutor Viviana Fein is accused of malpractice and taken off the case. A new investigation sensationally concludes that Nisman was murdered.

As the first people are indicted for Nisman's murders, contradictions between major players in the AMIA case come to light.
