Missing Billionaire, Stanford, Tracked Down by FBI

In a civil complaint Tuesday, the SEC accused Stanford, two other executives and three of his companies with committing an $8 billion fraud that lured investors with promises of improbable and unsubstantiated high returns on certificates of deposit and other investments. It's not clear how much of the $8 billion was lost and how much investors might recover.

Until regulators got help Thursday from the FBI, the SEC had not been able to find Stanford.
