A federal judge has dismissed the indictment against seven men accused in 2012 of cheating investors out of $132 million.

U.S. District Judge J. Thomas Marten granted on Monday the request from prosecutors to dismiss the case. Its end comes nearly three years after the government announced the indictment, alleging at the time that investors were bilked with false promises and phony reports about companies that leased drilling rigs and related businesses.

Prosecutors did not explain their decision in the filing, nor respond to email and phone messages seeking comment.

The order dismisses charges that had been filed against Michael McNaul, formerly of Hutchinson; Dale Lucas of Wichita; Russell Kilgariff of Preston; Lloyd Nunns of Hutchinson; Greggory Krause of Hutchinson; Steven Tallman of Owasso, Okla.; and Fredie Hembree of Hutchinson.
