Deadly poison in letter to US senator
Washington, April 17, 2013
US authorities on Tuesday intercepted a letter sent to Mississippi Senator Roger Wicker that preliminary tests showed contained the deadly poison ricin, and the Capitol police, FBI and other agencies have launched an investigation.
The letter has been sent for further analysis to an accredited laboratory, Capitol police said Tuesday night.
It was postmarked from Memphis, Tennessee, and had no return address, Terrance Gainer, the Senate sergeant at arms, said earlier in a warning to members of the Senate.
Gainer first said in a statement that the substance had tested positive for ricin, which is found naturally in castor beans and can cause death from exposure to as little as a pinhead amount, usually within the first 72 hours.
Police later issued a statement saying the test was "preliminary" and "indicated" that ricin had been found in the letter.
It was intercepted in a mail handling facility and quarantined, the statement said.
"Senate employees should be vigilant in their mail handling processes for ALL mailings," Gainer said in his written statement.
Members of the Senate were briefed on the incident by Gainer during a meeting with FBI Director Robert Mueller and Janet Napolitano, the secretary of Homeland Security, on Tuesday on the bombings in Boston.
Several senators told reporters after the briefing that the incident reminded them of the anthrax attacks in the wake of the Sept 11, 2001, attacks on the Pentagon and World Trade Center.
The ricin test came one day after the explosions at the Boston Marathon that killed three people and injured 176.
"I don't know if it's a coincidence. It's too early to tell. We don't know enough about Boston," said Senator Richard Durbin, the No 2 Democrat in the Senate.
Senate Majority Leader Harry Reid said he had been told the letter was addressed to Wicker, a Republican senator from Mississippi.
All mail to the US Senate had been stopped, and post offices at the Capitol had been closed as a precaution, the senators said. They were getting in touch with their state offices, where mail is not subject to the same extensive screening, to ensure that precautions were being put in place.
Many senators expressed concern about their staffs and the risks to postal workers.
They said they were aware of only one letter that had been intercepted that tested positive for ricin.
A law enforcement source, speaking on condition of anonymity, said initial field tests on the letter produced mixed results, prompting authorities to order further analysis at an accredited laboratory.
It was not immediately clear whether Wicker, a Republican, had attended the briefing by Mueller and Napolitano that was open to all senators from both parties.
Wicker issued a statement saying only that the matter was being investigated and expressing gratitude for thoughts and prayers on his behalf.
"This matter is part of an ongoing investigation by the United States Capitol Police and FBI. I want to thank our law enforcement officials for their hard work and diligence in keeping those of us who work in the Capitol complex safe," he said in the statement.
PREVENTION SYSTEM WORKED
Several senators noted that the system of mail screening, begun after the anthrax attacks, had worked.
"The bottom line is the process we have in place worked," said Claire McCaskill, a Democratic senator from Missouri. She said a suspect had been identified, and said it was someone who wrote to senators often.
Other officials could not immediately confirm that report. - Reuters
