    Suspicious White Powder Letters Received Around the United States

    Since Monday, December 8, letters containing a note and suspicious white powder have been received by the offices of more than 40 governors across the country. Additional letters have been received at several U.S. Embassies overseas, said Robert E. Casey, Jr., Special Agent in Charge, Dallas FBI.

    The white powder in each of these letters has been field screened and the tests have met with negative results. The powder has been forwarded to local laboratories and testing to date has been negative for biological agents. The FBI has contacted the governors’ offices and the State Department to be on the lookout for additional letters.

    Today, Mr. Casey announced the release of additional information regarding these mailings, to solicit the public’s help to identify the person or persons responsible for these crimes. Photographs of envelopes sent to governors’ offices are below. Although the photographs are of the envelopes sent to the governors of North Carolina and Connecticut, they are similar in content to all letters sent to the governors’ offices and embassies overseas.

    These envelopes have the following characteristics:

    1.The postmarks reflect mailing on December 4, December 8, or December 11, 2008.

    2.The postmark is either “Dallas, Texas” or “North Texas”. The “North Texas” postmark reflects the envelope was processed through the mail facility in Coppell, Texas, a suburb of Dallas.

    3.The return addresses used have been one of four addresses for FBI offices in Dallas, San Antonio, Houston, and El Paso, Texas. Names have been redacted from these addresses; the FBI is not disclosing the names at this time.

    4.There is a note within the envelope. The content of that note has been the same in each mailing. Although the content of the note is not being disclosed at this time, the meaning of the message is not clear.

    Although the substance contained in the mailings is not harmful, the threatening mailings not only constitute a federal crime, but cause alarm to victims and victim institutions and expend costly resources of police, fire, and other emergency responders and state, local, and federal laboratories.

    The FBI and United States Postal Inspection Service intend to vigorously investigate these crimes and arrest the person or persons responsible.

    The Postal Inspection Service is offering a reward of up to $100,000 for information leading to the arrest and conviction of the person or persons responsible for these mailings.

    Anyone with information on who may be sending these letters is requested to contact the FBI at 1-800-CALL FBI (1-800-225-5324), the Postal Inspection Service at 877-876-2455, or local law enforcement. If you receive a letter, please notify the FBI and your local authorities. Information on how to handle a suspicious package can be found on

    Since November, 106 suspicious packages have been sent to U.S. embassies, churches and National Guard bases around the country and the world.

    ...51 packages sent to National Guard offices around the country.

    all of the letters sent to the governor’s offices have Texas postmarks, while all of the letters sent to the National Guard offices have a Tennessee postmark.

    I wonder where the embassy letters are postmarked from?
