Argentine President Cristina Kirchner said Thursday that the prosecutor who investigated a 1994 bombing of a Jewish center did not commit suicide – and claimed he was murdered in order to implicate her in a cover up of Iran’s involvement in the deadly attack,.

“I’m convinced that it was not suicide,” Kirchner said in a stunning post on her Facebook page about the suspicious death of Alberto Nisman, who investigated the deadly attack on the AMIA Jewish charities federation center in Buenos Aires.

Kirchner contended that Nisman was killed to immerse her government in scandal after he had been “used” to publicly accuse her of involvement in the cover-up.

“Prosecutor Nisman’s charges were never in themselves the true operation against the government. They collapsed early on. Nisman did not know it and probably never knew it,” she said in the rambling post.

“The true operation against the government was the prosecutor’s death after accusing the president, her foreign minister, and the secretary-general of (her political faction) of covering up for the Iranians accused in the AMIA attack,” she said.

irchner offered no evidence to support her theory, and did not say who she thought was behind Nisman’s death.

Before his death, Nisman had filed a 280-page complaint charging that Kirchner had issued an “express directive” to shield a group of Iranian suspects in the bombing.

Kirchner’s comments come as evidence continues to mount that Nisman, who headed a probe which exposed Iran and Hezbollah as the perpetrators of the 1994 bombing, had not died at his own hands. It also marks a dramatic about-turn by Argentinian authorities in general, who initially attempted to play down the suspicious death as a suicide. 

On Wednesday, Argentine investigators said they found a footprint and a fingerprint in a recently discovered access hallway to Nisman’s apartment. The hallway links Nisman’s apartment to another unit that belongs to a “foreign man” – who may be an Iranian, according to some Argentinian media reports.

The corridor was reportedly often used by the technicians who maintain the building’s air conditioning system.

The investigative team is now trying to determine how anyone could have accessed that hallway and if someone could have used it to reach the bathroom where Nisman’s body was found, blocking the door from the inside.

The special prosecutor was found shot dead just hours before he was due to testify at an Argentine congressional hearing over his claims that the Argentinian government was trying to cover up his findings in return for oil deals with Iran.

Nisman’s body was discovered on the floor of the bathroom of his apartment on the 13th floor of Le Parc Tower on Sunday, with a .22 caliber pistol and one empty shell casing nearby.

Shortly following his death, it was revealed Nisman had received threats to his life over his investigation. That, along with other evidence of foul-play such as the lack of gunpowder on his hands and the fact that the pistol used did not belong to him, had already fueled suspicion in Argentina and elsewhere that he had been murdered.

Public anger over the official reaction to Nisman’s death – which officials initially attempted to dismiss as suicide – prompted the Argentine government to back a probe into his death.
