Joseph Jenkins Knapp, Jr. was expecting to receive a sizable inheritance upon the death of his 82-year-old great uncle, wealthy retired shipmaster and trader Captain Joseph White. But with debts piling up, Knapp decided he couldn’t wait for natural causes; in April of 1830, he and his brother, John Francis Knapp, hired a hitman to murder him, faked some blackmail letters, and, in the end, didn't get any inheritance at all.
