Lt. Antonio Vachris, the head of the Italian Detective Bureau in Brooklyn, stated that Petrosino was supposed to have been accompanied by police detectives in Palermo. He suspected that Petrosino was betrayed by someone within the Palermo police department and ultimately lured to his death. “He knew, as I do," Vachris told "The New York Times", "that Palermo is the worst hole in Southern Italy for the Mafia. In that city there are at least 100 criminals of the most desperate class who knew Petrosino. Because of his work many of them had been deported from this country, and he was a marked man with them.”
