Soon after the murders and an ensuing immigrant protest, the Italian government sent in the army to help the local police. Italy's Interior Minister, Roberto Maroni, said the Casalesi clan had "declared a war on the Italian state."
Setola had been on the run since last April, when he escaped the house arrest he had been granted based on a doctor's certificate that declared him virtually blind. Prosecutors are still trying to ascertain how he was let out of jail on an apparently fake infirmity.
In November police arrested a carabinieri officer suspected of tipping off Setola about police operations. The suspected "mole" commanded a carabinieri station near Casal di Principe -- the town in the area from which the Casalesi gets its name.
In the small, abandoned-looking house in the town of Trentola Ducenta from which Setola fled Monday, police found 12,000 euros in varying-size bank notes and Setola's wife, Stefania Martinelli, whom they arrested for possession of an undeclared pistol. She was questioned all night and will appear before the judge tomorrow.
The home was reportedly piled high with trash and appeared in squalid condition. Also found in the hideaway was an anti-anxiety medication, a bottle of Cartier perfume, a book by Pope John Paul II, "Rise, Let's Be On Our Way!" with an adoring dedication from a fellow clan member, and the book "The Gold of the Camorra," an investigative book written about the Casalesi clan.
Neighbors in Trentola Ducenta questioned on Italian state TV turned their backs on a television reporter. "I don't know anything and I haven't seen anything," said one unidentified neighbor.
"Why should I care? I don't even know who he is," said one young man who was interviewed.
Italian news programs aired video of Setola's hideaway, filmed after his escape that showed a bedroom furnished with a double bed and a wardrobe and another single bed in the kitchen. Police were seen shining flashlights down the trap door into the sewer, and a number of uniformed policemen were shown rather dejectedly on guard or searching the messy rooms in the house.
The humble home, however, was reportedly fitted with at least two-closed-circuit TV cameras on the outside walls, which were monitored in the kitchen and might have tipped off Setola to the police's imminent arrival.
The prefect of Naples, Alessandro Pansa, a long-time investigator of organized crime in Italy, told reporters today that "the police force's commitment to capture dangerous criminals is unquestionable. ... The capture of fugitives is a bit like a game of roulette: Sooner or later the winning number will be the one."
Monday, one of the magistrates on the Setola case received an envelope containing five bullets accompanied by an anonymous threatening letter, according to Italian newspaper Corriere della Sera. It was mailed from Marcianise, which is in the Casalesi-controlled territory.
