Yesterday

Mr. Yesterday was the man responsible for the construction of the Villa.

Background
Mr. Yesterday was the manager in charge of the Sierra Madre Villa construction. Although an affable, likeable person on the surface and a "friend" of Sinclair's, he was actually a con artist, planning to make the Villa his biggest steal ever. Cutting corners and expenses, storing money in personal accounts, substituting materials with cheaper, less efficient ones, he's done it all. Any incidents, such as the patio collapse in Salida del Sol, were covered up extensively: medical records deleted, witnesses paid off, and the whole affair protected legally. Everything was set up for the biggest con in history. Any problems were scrutinized by Mr. Yesterday to ensure that he is turning a profit. All with the help of the corrupt Villa staff.

He had a very profitable relationship with the construction crew foreman, paying him off and delivering hard liquor and chems to workers right under Sinclair's eye. Why? Because despite Sinclair's hardnosed insistence of his "contraband" policy, he really didn't care. He was more concerned with external security and items that could prove to be dangerous to the Madre. Going so far as to install a state of the art automated security system to return the items to the visitor's source address. However, when the Cloud placed at the Madre by Big MT as part of its research program began to manifest itself, problems started. Workers affected by its aggressive nature were hospitalized, with Yesterday delivering chems and cash to keep them silent. The delays combined with the Cloud led to the Villa not being entirely finished.

Although most were content with their under-the-table deals, the foreman of the Puesta del Sol section wasn't. He secured evidence to blackmail Mr. Yesterday into increasing his cut of the swindling. He then proceeded to confront Yesterday about his renegotiation, who agreed to meet him at the switching station so as not to be overheard. At the meeting however Mr. Yesterday murdered the foreman and made the incident look like an accident. Afterward Dean Domino swung by the foreman's crew to check if anyone else was in on the foreman's scheme. Yesterday's fate remains unknown, although hopefully, he has paid for his crimes, interred by the Madre.
