"Durham has earned a place among the greediest, most selfish and remorseless of criminals," Hogsett wrote in a sentencing memorandum earlier this week.
Attorneys for the defendants were hoping for shorter sentences.
John Tompkins, an attorney for Durham, has asked that the financier be sentenced to three years in prison and two years of home detention. Attorneys for Snow and Cochran also requested sentences lower than those recommended.
Snow's attorney, Jeffrey Baldwin, noted in a sentencing memo that former Enron Corp. CEO Jeffrey Skilling was sentenced to less than 25 years in prison after his convictions on 29 counts of fraud and conspiracy, while former WorldCom Inc. CEO Bernard Ebbers was sentenced to 25 years after being convicted of nine felonies including securities fraud in a loss of more than $1 billion.
The charges against Durham led several GOP politicians, including Indiana Gov. Mitch Daniels, to return hundreds of thousands of dollars in campaign contributions sought by Fair Finance's bankruptcy trustee.
