Saddam Hussein loses the Gulf War and orders aides to destroy stocks of germ-filled bombs. Regime officials lie to U.N. inspectors about prewar program and hide evidence of biological warfare factories.
A U.N. weapons inspector speculates in a memo that Iraq may be using mobile germ production facilities to hide its bio-warfare program. U.N. launches unsuccessful raids to find the suspected germ trucks.
Curveball gets job
Curveball is hired out of engineering school at Baghdad University to work at the Chemical Engineering and Design Center. He says he is first in his class, but records later show that he was last in his class.
Enter 'Dr. Germ'
Curveball says he is assigned to help his boss, Dr. Rihab Taha, also known as "Dr. Germ," as she begins planning for secret assembly of vehicles that can brew deadly germs and avoid detection.
An Iraqi admission
Regime officials admit to U.N. inspectors that Iraq produced and weaponized anthrax, botulinum toxin, aflatoxin and other biological poisons before the Gulf War. CIA analysts suspect Baghdad has secret mobile labs.
Curveball says he helped assemble a germ-production unit on trucks at Djerf al Nadaf. But the Iraqi says he did not see the unit in use, and did not know what germs it was designed to produce.
