A Chicago jury convicted Rana in June 2011 on the charges of providing Headley cover as an employee of his immigration business to scout targets in Mumbai and the newspaper office in Copenhagen.
In court filings this week, federal prosecutors described the alleged Danish plot involving beheading newspaper employees and depositing their heads onto Copenhagen streets as "murder on a grand, horrific scale".
Prosecutors said Rana, who lived in Chicago and owned a Northwest Side immigration and travel service, operated the business as a front for funnelling terrorist money overseas.
