"U.S. officials, who spoke on condition of anonymity because of the sensitivity of the ongoing grand jury investigation, said prosecutors were closing in on Ivins, 62. They were planning an indictment that would have sought the death penalty for the attacks, which killed five people, crippled the postal system and traumatized a nation still reeling from the Sept. 11 attacks.
Authorities were investigating whether Ivins released the anthrax as a way to test his vaccine, officials said. The Justice Department has not yet decided whether to close the investigation, officials said, meaning it's still not certain whether Ivins acted alone or had help. One official close to the case said that decision was expected within days."
