Salvatore Maranzano
Salvatore Maranzano was an organised crime boss and bootlegger operating in New York City in 1927. Maranzano was ordered by someone significantly more powerful than him to keep a sealed container in a locked dockside warehouse. Maranzano was unaware of the true identity of his superior nor of the contents of the container, but he was terrified of what it might be, and was eager to have it destroyed. Sometime later, under the pretense of stopping competing bootleggers, he sent his men to abduct two individuals who he suspected had come to deal with the mysterious container. After he was satisfied that Jack Harkness and Angelo Colasanto were the right people, Maranzano forced Harkness to swear that they would transfer the container to another warehouse without opening it — thus protecting Maranzano from retribution.(TW: Immortal Sins)
