Case into Nisman’s death in Argentina stuck in limbo

The investigation into the mysterious death of a prosecutor probing Argentina’s worst terrorist attack is in limbo after the country’s top penal court said Thursday that there’s not enough proof to determine that he was killed.

Nearly 18 months after Alberto Nisman’s death, authorities have yet to determine whether he took his own life or was killed by someone else. Nisman was found dead in his apartment on Jan. 18, 2015. Days earlier, he had accused then-President Cristina Fernandez of helping Iranian officials cover up Iran’s alleged role in the unsolved 1994 bombing of a Jewish community center. Fernandez denied the allegations and judges threw out the case.

Conspiracy theories have swirled around the case: some people believe Nisman killed himself because he felt his claims against the former president lacked proof, others say he was murdered because he was a threat to the Argentine and Iranian governments.

The decision on the unsolved Nisman case was announced Thursday by Argentina’s Criminal Appeals Court. The case will now return to lower court Judge Fabiana Palmaghini who tried to push the case to federal court in March.
