Sam's most recent run isn't something he'll ever claim credit for. Seems a mid-to-high level finance manager at Saeder-Krupp met a nice young man for lunch one day; a few months later, he found that a significant chunk of the company's funds had disappeared. Suspecting embezzlement, he contacted security to have them track down the perpetrator. When they reported to his boss that the money had been transferred to a series of untraceable accounts using his credentials, the manager found out and committed suicide.
Around the same time, and completely coincidentally, the Yakuza experienced a slight surge of income.
