Ex-wife of dead Argentine prosecutor rejects suicide claim

The ex-wife of a dead Argentine prosecutor rejected claims he'd killed himself and called for independent oversight of the probe Thursday, a day after huge crowds called for justice in the case.
Alberto Nisman was found dead last month, just days after accusing Argentina's President Cristina Kirchner of interfering in the investigation of a 1994 bombing of a Jewish center and covering up the role of Iranian officials. The attack killed 85 people and wounded 300 more.
Judge Sandra Arroyo Salgado said nothing in her ex-husband's personality led her to suspect he took his own life.
"He had no reason to do this, considering his personality. I do not see this possibility, much less so with the use of a gun," Arroyo Salgado said.
She told Vorterix radio that if Nisman was murdered, it was "very sophisticated."
Arroyo Salgado also called for the Inter-American Commission on Human Rights to oversee the death probe due to the difficulty of carrying out an impartial investigation.
The charges drawn up by Nisman were subsequently endorsed by a new team of prosecutors and are now before a judge.
Kirchner previously suggested Nisman was killed by rogue intelligence agents, and has asked lawmakers to disband the country's Intelligence Secretariat.
Arroyo Salgado took part in a march Wednesday, when tens of thousands of protesters gathered in Buenos Aires and cities across the country to pay tribute to Nisman and to demand justice.
Investigators say there were no signs that Nisman resisted an attack in his apartment in a guarded neighborhood in the capital. They initially said the 51-year-old's death appeared to be suicide, though that theory is widely disbelieved in Argentina.
Nisman was appointed by Kirchner's husband, late-president Nestor, to lead the stalled investigation of the bombing.
In 2006, Nisman accused several senior Iranian officials of involvement in the bombing of the Argentine Jewish Mutual Association.
In 2013, Kirchner signed an agreement with Tehran to resolve the case. On January 14, Nisman accused Kirchner of covering up Iran's involvement in exchange for oil.
