Questions Swirl over Death of Argentina Prosecutor

People in Argentina took to the streets on Monday over the shooting death of Alberto Nisman. He'd been scheduled to testify that day about accusations against President Cristina Fernández de Kirchner. She first claimed Nisman's death was a suicide — but today she's saying otherwise.

For 10 years, Alberto Nisman investigated the bombing of a Jewish center in Buenos Aires that killed 85 people. He claimed that Iran orchestrated the incident—and that President Kirchner was part of a cover-up. Nisman was shot to death one day before he was scheduled to present evidence to lawmakers. Taos Turner, who is reporting from Buenos Aires for the Wall Street Journal, picks up the story.
