This could have been a attempt to pump and dump.Turk had about 23 million shares come out of lockout the end of July and he may have wanted to dispose of them. From a recent SEC filing:
"Mr. Turk signed a Lockup Agreement and agreed not to sell the common stock underlying his shares of Series A Preferred Stock until July 31, 2006. Additionally, under the Agreement, Mr. Turk cannot sell or otherwise dispose of 22,930,067 shares of common stock or any options, warrants or other rights to purchase shares of common stock or any other equity security of the Issuer which Mr. Turk owns or has a right to acquire as of the date of the Agreement, other than in connection with an offer made to all shareholders of the Issuer or any merger, consolidation or similar transaction involving the Issuer, until July 31, 2007".
