Letter testing positive for Ricin sent to President

[Cheshire Cat]

A letter sent to President Obama has tested positive in an initial screening for the poison Ricin.  It is being reported through multiple news agencies that some of the filters in the mail facilities for the Capital have also tested initially for Ricin.  White house police have detained a person with a backpack filled with "suspicious" letters, some received outside of protocol when delivered to various offices at the Capital.  According to police the person caught their attention as they were acting strangely.  No word on whether or not those letters actually contained Ricin or to whom them were addressed.http://www.reuters.com/article/2013/04/17/us-usa-obama-letter-idUSBRE93G0OU20130417
