Nisman case: Argentinean prosecutor says for first time that Nisman was murdered

Sáenz said the investigation should now be carried out by the Buenos Aires federal chamber, which has jurisdiction in the case.
Nisman’s former wife, Sandra Arroyo, had always maintained that the prosecutor was murdered.
The leftist Fernández de Kirchner government had blamed the conservative forces for trying to accuse its officials of a cover-up.
The inquiry had been stalled for more than a year as investigators could not determine a cause of death.
Ricardo Sáenz, the chief prosecutor at the Argentina federal judicial chamber, said in a writ that Nisman did not commit suicide – the first time that an official authority has clearly identified the death as a possible murder case.
