Bernie Madoff's younger brother got sentenced to 10 years in prison today after admitting to crimes such as falsifying documents and lying to regulators. But Peter Madoff, 67, continued to insist he didn't know about Bernie's massive Ponzi scheme, a claim the judge called "frankly not believable," reports AP. Peter Madoff's plea deal also calls for him to forfeit $143 billion. He doesn't have it, but the New York Times says it's a "clear signal that the government will seize all of his assets and distribute them to victims." Five others face trial next year for their alleged roles in the scheme.
