Now, the FBI is releasing photographs of one of the hoax letters and its envelope in the hopes that citizens might be able to help solve the case.
- So far, more than 50 letters have been identified, nearly all of which use threatening language. The letters have all been mailed from Texas and postmarked at Amarillo.
- Most of the letters contained some sort of powdery substance. All field tests to date have turned up negative -- the powder appears harmless. Additional testing is taking place at regional laboratories.
- The letters have been sent to at least 11 states, including Arizona, California, Colorado, Georgia, Illinois, New Jersey, New York, Ohio, Oklahoma, Texas, and Virginia.
- Chase Bank
- The Federal Deposit Insurance Corporation, or FDIC, an independent federal agency
- The U.S. Office of Thrift Supervision, which regulates all federal and many state thrift institutions

"People who have mailed these kinds of hoax letters in the past have received some serious jail time," says Special Agent Richard Kolko, chief of the FBI's National Press Office in Washington, D.C. "This investigation will continue until those responsible are arrested, and we appreciate the public's support by providing information."
