"The charges that Mr. Brown pleaded guilty to also included helping one of his co-conspirators, Pawel Dynkowski, set up an offshore bank account to hold money from the Asia Global pump-and-dump. According to the indictment, he travelled to Costa Rica with Mr. Dynkowski on Oct. 21, 2006, to open an account that would be hidden from the U.S. Securities and Exchange Commission. After the men finished the trip, Mr. Dynkowski confirmed in an instant message that his "set up is now 100% sec safe."
