Independent tests show that Argentine special prosecutor Alberto Nisman was murdered, his family says.
At a news conference, Mr Nisman's ex-wife said the findings ruled out theories of accident or suicide.
Mr Nisman was found dead in his home on 18 January, hours
before he was due to testify in Congress against President Cristina
Fernandez de Kirchner.
He was probing Argentina's deadliest terrorist attack, the 1994 bombing of a Buenos Aires Jewish centre.
Sandra Arroyo Salgado, Mr Nisman's ex-wife, said a team of
experts had made their conclusions based on reports from a post-mortem
examination and existing forensic evidence.
Ms Salgado, a federal judge, added that her report was at
"the disposal of the prosecutor and judge" involved with the official
investigation into Mr Nisman's death.
Despite telling journalists the report's conclusions, Ms Salgado has not released the full details of the document.
