In a case of a government conspiracy that turned out to be true, Argentina’s attorney general for criminal appeals, Ricardo Sáenz, declared on Thursday that the death of Argentinean special prosecutor Alberto Nisman, who was Jewish, in January 2015 was not a suicide, as previously announced, but a homicide.

Sáenz said to the media that there was no gunpowder residue on Nisman’s hands and his body had been moved after death. He also stated that Nisman had received death threats and his body showed signs of having been beaten.

“The evidence shows that major changes were made in the crime scene. There is no doubt that it was not Alberto Nisman who fired the gun that killed him,” ” he said, adding, “The evidence up to this point supports the hypothesis that Alberto Nisman was the victim of the crime of homicide.”

The ruling presented before the Appeals Court came as a result of a case brought by Nisman’s daughters, mother and sister, who launched a private investigation into his death.

Nisman’s body was found January 18, 2015 with a gunshot wound to the head hours before he was to give testimony to Argentina’s congress that was expected to implicate Argentina’s President Cristina Fernandez de Kircher in a plot connected to a terror attack. Nisman had drafted warrants for the arrest of President Fernandez and Hector Timerman, Argentina’s Foreign Minister, before his death, but the document was found in the garbage in his apartment.

A .22 caliber handgun and a bullet casing were next to his body, which lay in the bathroom, blocking the door. The two doors to his apartment were locked, but a locksmith called to the scene said the doors where not well locked. DNA from another person was found on a cup in the sink. Viviana Fein, lead investigator in the case, said that traces of DNA found on the pistol, its ammunition, and other items from the scene “undoubtedly” matched Nisman, indicating suicide as cause of death.

In June, a video was released of the crime scene investigation showing police allegedly tampering with evidence by neglecting certain precautionary measures.

In January, police discovered an additional entrance to Nisman’s apartment, a hallway that connected Nisman’s apartment to another unit owned by a foreign resident. Police found a previously unknown fingerprint and footprint there.

Nisman was the chief investigator of the 1994 truck bombing of the Asociacon Mutual Israelita Argentina (AMIA), the Jewish center in Buenos Aires, which killed 85 people and wounded 300. It was the worst terror attack in Argentina’s history. In October 2006, he formally accused the government of Iran of directing the attack and ordering Hezbollah to carry it out.

After Nisman’s death, the Argentinian court released his report, which implicated government officials, judges, intelligence agents and intelligence officers who were allegedly involved in an attempt to cover up Iran’s involvement in the attack so Argentina could import oil from Iran and export grains to them.

President Fernandez claimed that Nisman had been tricked by a former Argentine spy chief into fabricating baseless allegations in order to destabilize her government and defame her. She theorized that the ex-intelligence officer then needed to kill him in order to maintain the subterfuge.

Nisman’s accusations against President Fernandez were dismissed by an Argentinina court and it was ruled that there was not enough evidence to continue the investigation.
