Medical Teams Gather to Investigate the Death of Alberto Nisman

Two medical teams are meeting in Argentina's capital in an extraordinary session aimed at concluding whether the head prosecutor investigating the country's worst terrorist attack killed himself or was slain by another person. The meeting began Wednesday after months of debate about how Alberto Nisman died Jan. 18, when he was found in his bathroom with a bullet in his head. The shot that destroyed Nisman's skull was fired with a gun that was loaned to him by aide Diego Lagomarsino, a computer technician who said the prosecutor asked for the weapon because he feared for his and his daughters' lives.
