A mafia informant who will give potentially crucial evidence in
any second trial of David Eastman faces serious and dangerous
retribution if his identity is revealed, a judge has said. The
informant, known only as "Witness A", could form an important part
of Eastman's defence, should he face trial again for the murder of
Assistant Federal Police Commissioner Colin Stanley Winchester in 1989. The
witness provided information to Victoria Police suggesting that another
person with no connection to Eastman may have been responsible for Mr
Winchester's murder. Revelations about the witness, heard during
the inquiry into Eastman's conviction last year, breathed new life into
an alternative theory that the Calabrian mafia, or 'Ndrangheta,
assassinated Mr Winchester in the belief the senior policeman had
double-crossed them.
