Frank Serpico is now an Italian citizen.
His parents had emigrated from Marigliano (Na) and he was born in New York in 1936.
Serpico’s story became known worldwide after Peter Maas wrote a book about the deadly struggle he had engaged against corrupted fellow cops. Then an iconic movie was shot in 1973, directed by Sidney Lumet and with Al Pacino interpreting Serpico.
