Authorities have arrested a Mississippi man believed responsible for letters apparently tainted with the poison ricin that were sent to President Obama and government offices, including that of Sen. Roger Wicker, R-Miss.
The FBI identified the man as Paul Kevin Curtis of Corinth, Miss.
He was arrested at his home at approximately 5:15 CT, the FBI said in a written statement, adding he was "believed to be responsible for the mailings of the three letters sent through the U.S. Postal Inspection Service which contained a granular substance that preliminarily tested positive for ricin. The letters were addressed to a U.S. senator, the White House and a Mississippi justice official."
