CORINTH, Miss. — A Mississippi man was arrested Wednesday, accused of sending letters to President Barack Obama and a senator that tested positive for poisonous ricin and set the nation's capital on edge a day after the Boston Marathon bombings.
Paul Kevin Curtis, 45, was arrested at 5:15 p.m. at his apartment in Corinth, near the Tennessee state line about 100 miles east of Memphis, said FBI Special Agent in Charge Daniel McMullen. It wasn't immediately known where he was being held.
Authorities still waited for definitive tests on the letters to Obama and Sen. Roger Wicker, R-Miss. Preliminary field tests often can show false positives for ricin. The letters were intercepted before reaching the White House or Senate. Ricin is derived from the castor plant that makes castor oil. There is no antidote, and it is at its deadliest when inhaled.
