According to Bloomberg, in addition to conspiracy to commit fraud, the parents now face an additional charges of conspiring to launder the bribes and other payments they may have made to the admitted mastermind of the scheme, the U.S. attorney in Massachusetts said Tuesday.

"The prosecutor's case against Mr. McGlashan is deeply flawed and ignores important exculpatory facts," his lawyer said in a statement. "We look forward to presenting his side of the story."
