These ex-employees were convicted of helping Bernard Madoff pull off his $20 billion scam -- the largest in history.
After nearly 6 months on trial, Bernard Madoff's former employees were found guilty of participating in the world's biggest Ponzi scheme.
Annette Bongiorno, a former employee of Ponzi mastermind Bernard Madoff, said she spent 40 years recording trades that it turned out didn't actually exist.
Bernard Madoff's ex-operations chief Dan Bonventre testified in federal court Tuesday that he had no knowledge that the firm where he worked for 40 years was a front for a massive Ponzi scheme.
