ROME — Police captured Cosa Nostra's No. 2 in a raid in Sicily and nabbed another Mafia fugitive strolling down a Milan street Saturday, as authorities crossed more names off the nation's most wanted list, Italy's interior minister said. Convicted Mafioso Gianni Nicchi, captured in the Sicilian city of Palermo, is a "young, dangerous, ambitious, pitiless killer," Minister Roberto Maroni said.
