A mysterious person called "Fallen Angel" have sent letters of Ricin in an attempt to change federal trucking regulations.
According to this CNN article, this was his demand:
The typewritten letter was addressed to the Department of Transportation and demanded that changes in truckers' sleep/work schedules not be implemented.
"I have easy access to castor pulp," the author of the letter wrote, referring to the waste of castor bean processing which can be used to make ricin.
"If my demand is dismissed I'm capable of making ricin," the letter continued. "My demand is simple, January 4, 2004 starts the new hours of service for trucks which include a ridiculous ten hours in the sleeper berth. Keep it at eight or I will start dumping."
Those federal regulations did go into effect Sunday, allowing long haul drivers to be on the road for 11 hours after 10 hours off-duty.
The author, who claimed to be a fleet owner of a tanker company, signed the letter, "Fallen Angel."
1st Letter:
To Department of Transportation, intercepted at Greenville, SC.
2nd Letter:
To White House. Intercepted at sorting house. Not disclosed because the government believed ricin posed "no public health risk".
3rd Letter:
A Ricin Letter was delivered to Senate Majority Leader Bill Frist. At first,
there appear to be no link to the first Ricin case mentioned above...but it seemed that there was a link being discovered.
Apperantly, the US government is stumpted over who is responsible for the ricin letters...but appear to have concluded that
the Ricin Attacks was a hoax , conducted by a prison inmate. So, it might be an iffy case.
