A 21-year FBI veteran with experience investigating terrorism, organized crime and drug-trafficking cases is the new head of the agency's high-profile Chicago office.
The FBI announced Cory B. Nelson's appointment Wednesday afternoon.
As the special agent in charge in Chicago, he'll be responsible for overseeing operations in northern Illinois.
Nelson replaces Robert Grant, who recently retired to take a global-security position with Walt Disney Co. in Los Angeles.
The Chicago office has taken the lead in multiple high-profile investigations, including the corruption case of former Illinois Gov. Rod Blagojevich and terrorism links to the 2008 attacks in Mumbai, India.
Nelson most recently served as deputy assistant director of the FBI's inspection division in Washington, D.C. He previously headed the agency's San Antonio office.
