Page 6 of the FBI’s search warrant affidavit in the Ivins’ investigation states:
“Of the sixteen domestic government, commercial, and university laboratories that virulent RMR-1029 Ames strain Bacillus antrhracis material in their inventory prior to the attacks ….”
As the Baltimore Sun summarizes it:
“The government said that 16 government, commercial and university labs had the strain of anthrax with the same genetic mutations as the anthrax used in the attacks.
And even at Fort Detrick, the government said that more than 100 people had access to the flask, creating a lot of room for reasonable doubt.”
