OXFORD, Miss. (April 17, 2013)--A man was arrested Wednesday in Mississippi in connection with letters containing suspected ricin poison that were sent to President Barack Obama U.S. Sen. Roger Wicker, R-Miss.
FBI Special Agent in Charge Daniel McMullen said Paul Kevin Curtis, 45, was arrested Wednesday afternoon at his apartment in Corinth, near the Tennessee state line about 100 miles east of Memphis, Tenn.
Authorities were waiting Wednesday night for the results of definitive tests on the letters to Mr. Obama and Wicker, which raised concerns at a time when many people were jittery after the Boston bombings.
An FBI intelligence bulletin that The Associated Press obtained said the two letters were postmarked Memphis, Tenn. and were dated April 8.
Field tests for ricin were positive, but lab tests are required to confirm the presence of the potential deadly poison.
In the bulletin the FBI said the letters both read, “To see a wrong and not expose it, is to become a silent partner to its continuance."
The letters, which were signed, "I am KC and I approve this message,” were intercepted at off-site mail facilities.
The FBI said there was no indication of a connection to the bombing at Monday's Boston Marathon.
