No gunpowder traces found on Nisman’s hands, tests ordered on alleged weapon
The forensic analysis on AMIA special prosecutor Alberto Nisman’s body confirmed that there were no traces of gunpowder on his hands. However, experts explained that it does not contradict suicide hypothesis.
Prosecutor Viviana Fein, who leads the investigation of Nisman’s death, said this was not an “unexpected result” and that it “does not rule out the possibility that Nisman had fired the gun himself.”
Fein had already confirmed yesterday that there was no sign of a third-party being involved in the death, but she had refused to rule out the possibility that the deceased was forced to take his own life by some as yet unknown factor.
She explained that the with .22 caliber fire arms, as the one used in Nisman’s death, “usually do not deliver positive results” for gunpowder traces in forensic analysis.
"When the weapon is fire, since the quantity [of gunpowder] for an electronic sweep test is so small, the test could not give a positive result," Fein underlined.
"[The gun] is not a weapon of war, it usually does not allow for an electronic sweep to show up as positive."
The investigator, with consent from judge Emma Palmaghini, subsequently ordered new studies on the .22 calibre pistol to be carried out. The gun will be fired by a different person whose hand will undergo the same test as Nisman's, to determine whether it leaves gunpowder residue.
"There are so many tests that can be ordered in this case, we must wait for blood studies found on the gun and on the scene to yield results," Fein added. She also gave some information on the Prosecutors' office employee who had lent the weapon to Nisman shortly before his death.
"He has worked there since 2007 specialising in information technology, a technical part of the prosecution unit, and he worked mostly on Nisman's requirements. He is a technician, a Computer Science graduate," she indicated."We have not taken any other weapon from doctor Nisman's home, nor from safes, drawers or any other places they could be appropriately stored. Right now no other weapon has been found or taken."
