The Ponzi scheme that devastated Napa Valley. In 1988, a daring San Francisco drug bust led investigators straight to a massive financial fraud scheme in the Napa Valley. Hundreds of residents, many of them elderly, had entrusted their life savings to respected businessman David Hanson only to lose everything as his scheme unraveled. The destruction spread like ripples in a pond, with victims losing retirement savings, houses, and more. Multiple arrests were made, and every trial revealed another twist. Join author and retired Napa Superior Court judge Raymond A. Guadagni as he tells the story of the pursuit of justice for the citizens of Napa.
