60 Minutes reports: Tables Turned In Anthrax Investigation

But five years after letters sent through the U.S. mail containing anthrax killed five and injured 17, the FBI has yet to charge Dr. Steven Hatfill. In 2003, he sued the government.

The resulting depositions of FBI personnel and law enforcement records obtained by 60 Minutes provide an inside look into one of the FBI's biggest investigations ever and raise the possibility that the bureau may have a cold case on its hands.

Correspondent Lesley Stahl's report, which contains revelations from those depositions, will be broadcast this Sunday, March 11, at 7 p.m. ET/PT.

Hatfill, a scientist who worked at an Army laboratory where the strain of anthrax used in the attacks was stored, is the only "person of interest" named publicly in the case. He has maintained his innocence all along.

Hatfill is suing the government for destroying his reputation by, among other things, naming him "a person of interest." According to depositions taken for Hatfill's suit and obtained by 60 Minutes, the FBI official who oversaw the investigation says the bureau was looking at many more people.
