It appears someone was trying to frame Dr. Assaad for an attack that hadn’t yet happened as far as the public knew.

It was well before anthrax panic gripped the nation — in fact, it was the same day that photo editor Robert Stevens, 63, was admitted to a Florida hospital.
It wasn’t until the next day that Stevens was diagnosed with inhalation anthrax, and another two days later, on Oct. 5, when he would become the first of five eventual fatalities caused by the apparent bioterrorist attack. The day after hearing from the FBI, Assaad met with special agents J. Gregory Lelyegian and Mark Buie in the FBI’s Washington field office, along with Assaad’s attorney, Rosemary McDermott.
They showed Assaad a detailed, unsigned, computer-typed letter with a startling accusation: that the 53-year-old Assaad, an Environmental Protection Agency scientist who filed an age discrimination suit against the U.S. Army for dismissing him from a biowarfare lab, might be a bioterrorist.Timelines:
