The FBI has disclosed two threatening
letters from a mysterious source that could shed light on who might have been
responsible for mailing the deadly poison ricin to a prominent senator earlier
this year - as well as an attempt to send it to the White House last year.
The FBI says two letters received at government postal facilities last October
both contained ricin and threatened more attacks if new regulations requiring
truck drivers to rest for longer periods of time were not repealed.
Both were signed by someone identified only as Fallen Angel. In one, the
writer, who claimed, according to the FBI, to own a fleet of tanker trucks
- threatened to produce large quantities of ricin if those federal regulations
were not rolled back. A second letter, this one addressed to the White House
but intercepted at a mail facility in Tennessee - threatened, "to turn Washington
into a ghost town" - if the new rules took effect.
The FBI is making the letters public at the same time it is offering a $100,000
reward. Officials hope it will lead to the arrest of whoever tried to send
ricin to the White House last year, as well as whoever succeeded in sending
a small amount of the deadly substance to Senate Majority Leader Bill Frist's
office earlier this year. There were no injuries, but Senate office buildings
were shut for several days, in an incident that was a reminder of the still
unsolved case of the anthrax spores mailed to Senator Tom Daschle in 2001.
