From a New York Times obit by Gaia Pianigiani headlined “Maurizio Costanzo, Who Transformed Italian Talk Shows, Dies at 84”:

Maurizio Costanzo, for decades one of Italy’s leading prime-time talk show hosts and most prominent television journalists, who had been living under police protection ever since he took on the Sicilian Mafia in 1993, died in Rome.

He had recently undergone colon surgery and was recovering in a private clinic, Elisabetta Soldati, a publicist for his family said.
