OKLAHOMA CITY (AP) — The FBI says an anthrax hoax that targeted federal government and Oklahoma state agencies was mailed by a state prison inmate.
FBI agent Martinus McConnell says the case is under investigation and no decision has been made on whether the inmate — whose name was not released — will face charges.
The head of the FBI's Oklahoma City office, James Finch, said Friday that the U.S. Attorney's Office in Muskogee received a letter from the inmate on Wednesday indicating a white powdery substance in the letter was anthrax. Similar letters were sent to the FBI and U.S. Attorney offices in Oklahoma City, the Oklahoma Attorney Generals' Office and federal courts in Oklahoma City and Washington, D.C.
Tests on the substance found that it was not hazardous.
