An arrest has been made in connection with possibly contaminated letters sent to President Barack Obama and Sen. Roger Wicker, the Department of Justice said Wednesday. Paul Kevin Curtis was arrested by the FBI at his home in Corinth, Mississippi, the department said in a statement. Discovered Tuesday, the letters were addressed to Wicker, a Mississippi Republican, and to Obama. The justice department release said a third letter was sent to a Mississippi justice official. The letters to Wicker and Obama were stopped at a government mail-screening facility after initial tests indicated the presence of the deadly poison ricin. Because initial tests can be "inconsistent," the envelopes have been sent off for additional tests, an FBI statement said. The FBI does not expect to receive results from the tests until Thursday, federal law enforcement sources told CNN.

Initial tests on those envelopes detected the deadly poison ricin; additional tests under way
However, the @placeholder said additional testing was needed because field and preliminary tests produce inconsistent results.
