(Washington, DC) -- A Tupelo, Mississippi man is under arrest in the mailing of ricin-laced letters to President Obama and U.S. Senator Roger Wicker. Federal officials are identifying the man as Kevin Curtis. Initial tests on the letters came up positive for ricin, a deadly poison that comes from castor beans. Reports say Curtis may appear in court as soon as tonight.
