Alberto Nisman, the Argentine prosecutor who was found dead in January while preparing a high profile case against his country’s president, did not fire the gun that was found by his body, ballistic reports have suggested.
In the latest twist to the case, a series of tests carried out in a laboratory in the northern Argentine city of Salta have shown that the gun that killed Nisman would have left traces of gunpowder on the hand that pulled the trigger. Tests done on Nisman’s hands in the days following his death found no such residue.
