A worker washes the sidewalk of the apartment building where the late prosecutor Alberto Nisman was found dead in Buenos Aires, January 21, 2015. The mysterious death of an Argentine prosecutor just days after he accused the president of directing a cover-up in the bombing of a Jewish community centre two decades earlier has jolted the country with accusations of foul play coming from all sides. The body of Nisman, lead investigator into the 1994 car bomb that killed 85 people, was found in his apartment on Sunday night, a handgun by his side along with a single shell casing.
