Forensic experts in Argentina have found DNA evidence of a second person in the apartment where an Argentine prosecutor was found dead last month in a case that has shaken the country.
Alberto Nisman was found in his bathroom on Jan. 18, a bullet in his head and a pistol by his side. He had been scheduled to bring a case to Congress the next day accusing president Cristina Fernandez de Kirchner of trying to derail the criminal investigation into possible Iranian involvement in the bombing that killed 85 people in a Jewish community center.
The judge in the case filed court papers saying a sample "corresponding to a genetic profile different from Nisman's" had been found; until Tuesday there had been no evidence of anyone else in Nisman's apartment.
The president's chief of staff told reporters on Tuesday that everything pointed to a suicide. But messages from the government, including the president, have been contradictory.
Friends have said Nisman showed no signs of being suicidal and was ready to go to Congress on Jan. 19 to present his case.
The next big step in the investigation is expected to be testimony by former Argentine master spy Antonio Stiusso, who was fired by the president in December. The government says Stiusso manipulated Nisman into leveling the conspiracy accusation against the president in reprisal for his firing.
