Federal authorities have dropped charges against a Mississippi resident detained last week for allegedly sending ricin-laced letters to President Obama, Senator Roger Wicker of Mississippi and a local official. Shortly after being released, Paul Kevin Curtis told reporters his arrest had been a “nightmare” ordeal.

Paul Kevin Curtis: “I respect President Obama. I love my country and would never do anything to pose a threat to him or any other U.S. 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.”

Hours after Curtis was released, the home of another Mississippi resident was searched in connection with the case.
