In August 2002, she convinced a Pakistani arms dealer that she was interested in buying weapons. When he offered to sell her U.S. Stinger missiles, she turned the information over to the FBI.
The following year, posing as an Algerian member of Al Qaeda, she spotted a man writing in English in another Arab forum. "Just curious," he wrote, replying to Rossmiller's e-mail, "would there be any chance a brother who might be on the wrong side at the present could defect?" In a series of 30 e-mail exchanges, Rossmiller established that the man was Spec. Ryan G. Anderson, a National Guardsman stationed at Fort Lewis, Washington. A Muslim convert, Anderson was on his way to Iraq and wanted to sell secrets of weapons vulnerabilities and information about troops to Al Qaeda.
Rossmiller turned over her information to the U.S. Department of Homeland Security. She was a central witness at Anderson's court- martial. He was convicted of treason and is serving a life sentence.
