Forensic tests on the body of Argentine state prosecutor Alberto Nisman who accused the President of a cover-up with Iran indicate that he was murdered , his ex-wife said today . He was found shot dead in the bathroom of his locked apartment in January , hours before he was due to testify against President Cristina Fernandez de Kirchner in the Argentinian Congress . He was trying to arrest the President after claiming she helped cover up Iran 's alleged role in a 1994 bombing which killed 85 at a Jewish community centre in Buenos Aires . The mysterious circumstances surrounding Mr Nisman 's death unleashed a storm of conspiracy theories . His ex-wife , Sandra Arroyo Salgado , hired a private team to analyse the autopsy results and run additional tests . On the offensive : Argentinian President Cristina Fernandez de Kirchner ( left ) has denied claims helped Iran cover up a terrorist attack . The claims were made by Alberto Nisman ( right ) - who was mysteriously shot dead . Argentine authorities have not released full results of his autopsy , more than six weeks after he was found sprawled in a pool of blood in his flat . The few details made public so far have suggested suicide , although the lead investigator into Mr Nisman 's death said she could not categorically say if he shot himself in the head or was killed . But today , his ex-wife - the mother of their two children - said : 'Nisman did n't have an accident . He did n't commit suicide . They murdered him . ' Earlier today , Ms Arroyo Salgado , who is a judge , deposited the forensic evidence backing up her allegations at the state prosecutors ' office in Buenos Aires . She did not give details of the findings to journalists . Yesterday , a full-page advert , signed by the Government of Argentina and bearing an Argentinian flag , questioned Mr Nisman 's motives and attacked his argument . 'One must ask oneself what objectives Nisman was pursuing with a complaint plagued with contradictions , lacking logic and without legal basis , ' it declared . Mrs Kirchner : The president 's name was on a draft warrant discovered in the home of Alberto Nisman . 'Can one think of a hypothesis other than seeking to generate a destabilising political effect ? ' Mr Nisman had accused the President and top administration officials of helping Iranian officials hide their and Iran 's alleged role in the country 's worst-ever terrorist attack . His 289-page investigation , which was published a few days after his death , was based on wiretaps of top administration officials that he argued proved the secret deal with Iran . According to Mr Nisman , the President allegedly orchestrated the deal in exchange for economic trade . Ms Kirchner rejected the allegations , and Iran denied any role in the bombing . The prosecutor was found shot in the head in his apartment in the capital 's upmarket Puerto Madero district on January 18 , triggering protests in the streets . His mysterious death triggered a PR fightback by the government , whose officials said the prosecutor was trying to smear the nation . Senior government official Gustavo Lopez claimed last month the allegations were part of an attempt to unseat the President and bring neoliberals back to power . 'We are facing an attempted coup d'etat , that aims to get rid of the president , ' he wrote . But the alleged smears have upset other politicians . Cornelia Schmidt-Liermann told the Associated Press : 'It 's awful to see so many accusations against a person who ca n't defend himself . 'Instead of clarifying anything , Fernandez is damaging the investigation into Nisman 's death . ' Anger : Protesters clashed with police after the death of the prosecutor in his locked apartment in January . Horror : The 1994 bombing of a Buenes Aires Jewish centre , run by the Argentine Israelite Mutual Association , left 85 dead and remains the country 's most deadly terrorist attack . Iran has denied it was involved . Yesterday 's newspaper advert highlighted a judge 's ruling which said Mr Nisman 's argument had a lack of 'coherence and integration ' . Judge Daniel Rafecas , who made the ruling , said : 'There is not a single element of evidence , even circumstantial , that points to the head of state . ' That ruling was appealed yesterday by prosecutor Gerardo Pollicita , who has taken up the case following Mr Nisman 's death . He said the judges ' decision was 'premature ' and an investigation was needed to 'prove or disprove the facts ' . The appeal sends the case to the Federal Chamber of judges , which can uphold or reject last week 's decision by federal Judge Rafecas . Argentinians will go to the polls in October , but the President is barred from running for a third term by the country 's constitution and will have to step down . She has nevertheless gone on the offensive , accusing opposition parties of using the row for political gain and claiming the U.S. and Israel were meddling in Argentina 's affairs .
