Convicted fraudster Daniel Two Feathers has agreed to plead guilty to a string of counts in relation to a Ponzi scheme involving Bermudian Andre Curtis.Federal court documents in the United States show Two Feathers has struck a plea agreement with the Attorney’s Office for the District of Montana over the scam which conned investors out of $4 million in 2008.He has agreed to plead guilty to conspiracy to commit investment fraud, investment fraud, receipt of stolen money in interstate commerce and money laundering.Those counts carry penalties of between five and 20 years in prison and fines of $250,000.The Montana Commissioner has previously ruled against Mr Two Feathers, Mr Swor and a number of co-conspirators, including Mr Curtis, the political campaign manager for former Premier Ewart Brown.The plea agreement states Two Feathers acknowledges that there was an agreement between two or more people to commit at least one crime of investment fraud.It states Two Feathers knowingly took part in a scheme to obtain money or property by false pretences, and by omitting facts when encouraging people to part with their money.A jury trial for defendant Shawn Swor has been fixed for Monday, May 7.Mr Curtis has previously been fined $335,000 and ordered to pay back victims he had duped by falsely promising massive returns as part of the scam.
