A new Senate investigation has revealed that six different U.S. banks helped former Chilean dictator Augusto Pinochet stow away more than $13 million. Riggs Bank, Citibank and Bank of America were all named in the investigation. Some of the banks allowed Pinochet to use assumed names on accounts. In addition, banks arranged international wire transfers and helped the Pinochet family set up offshore companies. An estimated 3,000 Chileans were killed by Pinochet’s regime between 1973 and 1990.
