MSNBC describes him as a Tea Partier in 3… 2… 1.
Via NBC News:
Federal agents on Wednesday arrested a suspect in the mailing of letters to President Barack Obama and a U.S. senator that initially tested positive for the poison ricin.
The suspect was identified as Paul Kevin Curtis of Tupelo, Miss., federal officials told NBC News. They said he may appear in court as early as Wednesday night.
Both letters carried an identical closing statement, according to an FBI bulletin obtained by NBC News on Wednesday.
According to the FBI bulletin, both letters, postmarked April 8, 2013 out of Memphis, Tenn., included an identical phrase, “to see a wrong and not expose it, is to become a silent partner to its continuance.”
In addition, both letters are signed: “I am KC and I approve this message.”
Under the heading, truth stranger than fiction, Kevin Curtis from Tupelo, Mississippi is a professional Elvis Impersonator, who goes by “KC” (short for Kevin Curtis). That also might explain why the letters are sent from Memphis, Tennessee, home of Elvis. On another site, he uses the same phrasing as in the letters sent above:
“It may take the rest of my life but I’ve been at it for 13 years now and have NO PLANS to stop this journey and crusade for JUSTICE. People called me “crazy” and a “nut” 12 years ago. Now…today..what are they calling me? Hmmmmmm……some food for thought. This is KC & I approve this message.“
Update: Lady Liberty makes a good case this is the guy.
