Ignazio Lupo, of No. 433 West Fortieth Street. Messina Genova, of No. 538 East Fifteenth Street. Vito La Duca, of No. 16 Stanton Street. Pietro Inzarillo, of No. 226 Elizabeth Street. Domenico Pecoraro, of No. 198 Chrystie Street. Lorenzo Lobido, of No. 308 Mott Street. Giuseppe Fanara, of No. 25 Rivington Street. Giuseppe La Lamia, of No. 47 Delancey Street. Nicola Testa, of No. 16 Stanton Street. Luciano Perrino, of No. 47 Delancey Street. Perrino was also known as Tomasso Petto. He was known among the members of the Black-Hand aggregation as "Il Bove," meaning "The Ox." Here was certainly a murderous aggregation of the most pronounced criminal type. They were all of them from Sicily. Most of them were armed with a revolver, some also had knives and even stilettos. On Morello the police found a .45 caliber revolver. A knife was tucked away in the waistband of his trousers, a cork being fixed at the point of the blade so that it would not scratch his leg. Petto, the Ox, whom Inspector McCafferty of the detective bureau, and I arrested later, carried his pistol in a holster and a sheath for his stiletto. Most of the suspects had permits from the New York Police Department to carry revolvers. It was this incident, practically, which brought on the crusade against, and the passing of the law forbidding, the carrying of dangerous weapons. The prisoners were presently hurried to the Morgue, where each of them had a look at the dead man. They were asked individually whether they knew him. The answer was the usual one--a shrug of the shoulders and the words "No understand," "don't know." Morello and Pecoraro were both asked whether they knew the dead man, but denied that they had ever seen him; this in face of my seeing the two in the company of the man now dead less than forty hours before he was murdered. The dead man still remained without a name, and without a friend or relative coming to claim kinship. Information began to percolate into my office which induced me to take a trip to Sing Sing prison in an effort to bring about the identification of the dead man. It was plain to me already then that the police force was failing in its efforts. I resolved to take a personal interest in the murder and to clear it up if possible. At this point, let me inform the reader that an anonymous letter was addressed to Lieutenant Joseph Petrosino of the Italian Detective Squad, then a part of the New York Police Department. This letter proved to be of value in elucidating particulars aiding us in identifying the man found murdered in the barrel. The Lieutenant showed this letter to me. Knowing that Petrosino was the best man in the Police Department to handle the situation, I asked him to go to Sing Sing Prison to investigate.
