U.S. District Court - Las Vegas, NV

Please be aware that the criminal prosecution in the District of Nevada (United States v. John Edwards, et al., 2:09-CR-00132-RLH-RJJ) is separate from and unrelated to a civil suit in the Central District of California that has now been dismissed (David Anderson, et al., v. Christopher Cox, et al., 8:10-CV-00031-JVS-MLG). In Anderson, the plaintiffs alleged that the SEC and other agencies of the U.S. Government conducted a sting operation against "illegitimate brokers, dealers, market makers, hedge funds, and other persons and entities that had engaged in naked short selling of CMKM Diamonds Inc. Stock." Essentially, the Anderson case involved allegations against an entire industry.

In contrast, the superseding criminal indictment in the Edwards case charged a more clearly defined group of defendants: specific insiders who engaged in fraud through shell companies. Specifically, between approximately May 1997 and April 2008, the defendants used various shell companies – including Pinnacle Business Management, Inc. (May 1997 to December 2003); CMKM Diamonds, Inc. (November 2002 to October 2005); St. George Metals, Inc. (July 2004 to July 2005); and Global Diamond Exchange, Inc. (November 2005 to April 2008) – to defraud purchasers of stock in those companies. The defendants secretly authorized increases in the number of available shares and falsely represented or hid the true number of shares from investors. At the same time, the conspirators issued billions of shares to themselves through affiliates. By falsely claiming that these shares had not been issued to company affiliates, the conspirators were able to sell these shares without restrictions imposed by law. By issuing false and misleading press releases regarding the companies’ business activities, the defendants were able to drive up demand for the companies’ stock while selling their shares at a profit.
