A federal official says the man charged with sending poison letters to elected officials has been released from jail.
Jeff Woodfin, chief deputy with the U.S. Marshals Service in Oxford, Miss., says Paul Kevin Curtis has been released from custody.
Charges were dropped late Tuesday after searches of Curtis' house failed to turn up ricin.
The development comes hours after officials canceled a detention and preliminary hearing Tuesday.
Curtis was arrested Wednesday at his house in Corinth and charged with sending ricin-laced letters to President Obama, Sen. Roger Wicker and a Lee County, Miss., judge.
Curtis spoke out after the charges were dropped.
Curtis says he respects President Obama, loves his country and that he "would never do anything to pose a threat."
Curtis says this week has been a nightmare.
