I believe there is probable cause to charge the defendant with these charges because:
On or about September 24, 2018, William Clyde Allen III sent, via postal mail, four letters containing ground
castor beans to the President of the United States, the FBI Director, the Secretary of Defense, and the Chief of
Naval Operations. During an interview of Allen III on October 3, 2018 Allen II confessed to having purchased
castor beans and having sent the letters. All four letters sent by Allen tested positive for ricin poison.
I believe these to be additional condition(s) for continued detention:
The person would constitute a substantial danger to any other person or to the community, or is likely to flee the
jurisdiction of the court
This is an FBI-led investigation and charges will be filed in federal court. We ask the subject not be released
because he poses a threat to the public. FBI will be taking custody of him on Friday, October 5, 2018 for his
initial appearance at Federal Courthouse.
