A former Minnesota bank CEO has been sentenced to 18 months in prison after pleading guilty to falsifying bank records.   While acting as the CEO of Border State Bank, Roger Hager misappropriated more than one-point-six-million dollars as part of a scheme investing in African diamonds and gold. After maxing out his own borrowing, Hager used loans from customers and shareholders as well as unreported Standby Letters of Credit to have the materials delivered from Africa. The former CEO will also serve two years of supervised release.
