Video: Jailhouse blocked: charges against ricin letter suspect dropped Following the discovery of letters containing ricin addressed to Barack Obama, Paul Kevin Curtis was arrested by the FBI at his home in Corinth, Mississippi last Wednesday and charged with threatening the life of the President. Lawyers for Mr Curtis suggested he was framed, and an FBI agent testified in court this week that no evidence of ricin was found in searches of his home. At a news conference, Mr Curtis said that he loved his country and "would never do anything to pose a threat to [President Obama] or any other US official." This past week has been a nightmare for myself and my family. My mother has suffered as well as my children. "I would like to get back to normal, which for me means being the best father that I could be to my children," he added. The move came as police searched the home of former politician J Everett Dutschke in relation to the case. Mr Dutschke, also from Mississippi, has denied any involvement.
