The FBI now says threatening letters were sent to several federal and state offices in Oklahoma.
James E. Finch, Special Agent in Charge of the Oklahoma City Division of the Federal Bureau of Investigation, says the United States Attorney’s Office for the Eastern District of Oklahoma in Muskogee received a letter from an Oklahoma state prison inmate indicating a white powdery substance in the letter was anthrax on Wednesday.
FBI agents interviewed the prisoner who sent the letter and learned similar letters were sent to the FBI in Oklahoma City and the Oklahoma State Attorney Generals’ Office, Oklahoma City.
They also learned additional letters were sent to the U.S. Court of Appeals, Washington D.C., the U.S. District Court, Oklahoma City, and the United States Attorney’s Office for the Western District of Oklahoma, Oklahoma City.
On Thursday, the U.S. Attorney’s Office, Oklahoma City, FBI Oklahoma City, and the Oklahoma State Attorney Generals’ Office all received letters containing a white powdery substance from the prison inmate indicating they contained anthrax.
The letter intended for the U.S. Court of Appeals in Washington D.C was intercepted by the U.S. Postal Inspector’s Office on Friday.
Initial field screening and preliminary lab test for hazardous substances were negative for the letters that contained a white powdery substance. The letter received by the U.S. District Court, Oklahoma City, on Thursday, was determined to be a complaint.
