The police named Robert Seldon Lady, the CIA's former Milan base chief, Jeffrey W. Castelli, the agency's former Rome station chief, and two others, identified as Sabrina De Sousa and Betnie Medero, as their CIA contacts, according to the source. All had previously been named in prosecution documents.
