DNA is called anthrax case key

WASHINGTON — DNA taken from the bodies of people killed in the 2001 anthrax attacks helped lead investigators to Bruce Ivins, who oversaw the highly specific type of toxin in an Army lab, a government scientist said Sunday.

Using new genome technology, researchers looked at samples of cells from the victims to identify the kind of anthrax Ames strain that killed them, the scientist said. They noticed very subtle differences in the DNA of the strain used in the attacks from that in other types of Ames anthrax.

With that, investigators linked the specific type of anthrax back to Ivins' biological weapons lab at Fort Detrick in Frederick, Md., where he oversaw its use and handling for research.

”It had to do with the very specific characteristics in the DNA of the letters and what was in Bruce's labs,“ said the government scientist, who is close to the investigation. ”They were cultures he was personally responsible for.“

The scientist spoke on condition of anonymity because he is not authorized to speak to reporters.

The scientific discovery gave the FBI its first solid break in one of the nation's most high-profile unsolved crimes. Combined with other evidence, the Justice Department is expected to close the case this week
