Hughes brought it about so that the consignment of olive oil to Lupo was held up, compelling Lupo himself to write out a list of the goods he desired to have admitted over his personal signature. The statement was then taken to a handwriting expert and also the letter containing the counterfeit five-dollar bill was placed at the disposal of the expert, who declared that the handwriting of the letter and that of the statement written by Lupo for his consignment of olive oil was one and the same. Now I had established a connecting link that would stand the test of the courts. But there were many other things about the letter that led me to go further before making any allegation against the wily Lupo. It occurred to me it might be well to know why the letter had been sent away out to a railroad camp in Portage La Prairie. I got men to work on that end of the case. We found that Andrea Pollara was a laborer in a railroad camp at the address to which the letter had been sent. Further, it was established that Andrea Pollara was the agent of the gang in the camp where a number of Italians were employed mending and building spurs on the railroad. He had been sent there to investigate and see whether it was a profitable place in which to distribute some of the spurious bills. Additional information disclosed the fact that the railroad camp had moved and the letter having been addressed to Portage La Prairie, and not being called for, was returned to the address written on the back, Giuseppe Conti, No. 8 Prince Street. This cleared up in my mind the reasons for the letter being sent to the Canadian railroad camp and also the cause of its being returned. Other little connecting links were established over which I was building a bridge to Lupo in his Italian grocery store. It came to my mind that Lupo had done quite some business with Banker Acritelli, and Lupo was also on more than familiar terms with Banker Pati. I knew that Lupo and Inzarillo were very friendly. It was found that the man to whom the letter had been addressed to in Canada was not Andrea Pollara. This was an assumed name. The right name of the "Black-Hander" was Salvatore Maccari, who had a wife living in New York City. The net of evidence was closing on Lupo. While I was gathering the threads together, the tragedy of the barrel murder came to public notice. While the police of New York were groping around in the dark, I submitted information of which I have spoken previously in this book, and the arrest of a number of the gang for the murder of the victim in the barrel followed. Among those arrested was Lupo. When he was placed in custody his house was searched, and the following letter, written in Italian, was found. It was postmarked Portage La Prairie, Manitoba, Canada, addressed to Pietro Inzarillo, No. 226 Elizabeth Street, New York City, dated September 4, 1902, and translated reads: "DEAR FRIEND:
