Argentina’s recently elected leader, Mauricio Macri, intends to make certain that justice is served regarding State Prosecutor Alberto Nisman's mysterious death.

The BBC reports the right-leaning Macri ordered the files on Nisman's death be made public on Jan. 15.

A year after the Argentine attorney was found dead in his apartment, it still remains unknown whether Nisman killed himself or was murdered.

As previously reported, Nisman's ex wife, Judge Sandra Arroyo Salgado, announced that the results of an independent investigation in Nisman's death found that he had been murdered. Nisman, who had been investigating the 1994 bombing at a Jewish center, had been worried for his safety days before he was found dead.

"Violent death only has three hypothesis: accident, suicide and homicide," said Salgado. "We can only conclude that Nisman was, without a doubt, a murder victim."

Nisman’s body was discovered hours before he was set to testify in Congress against former President Cristina Fernandez de Kirchner.

The Jewish Telegraphic Agency reports Macri spoke to Nisman's teenage daughters, Iara and Kala, on the eve of the first anniversary of their father's death.

By contrast, former president Fernandez de Kirchner never received Nisman’s relatives or even expressed any condolences to the Nisman family.

Nisman's eldest daughter, Iara, wrote an op-ed in which she expressed her belief that her father was killed in order to foster fear in people. "I hope that we can find the truth about my father," she wrote.

Before his death, Nisman had sued Fernandez de Kirchner for her government's alleged covered up Iran’s role in the 1994 attack on the AMIA Jewish center in Buenos Aires, which resulted in 85 people dead and hundreds more wounded.

The deadly attack came two years after 29 people died in a similar attack on the Israeli embassy in Buenos Aires.
