CNN: The Mississippi man accused of sending ricin-tainted letters to President Barack Obama and other officials has been released from federal custody, a spokesman for the U.S. Marshals Service said Tuesday.

Paul Kevin Curtis, an Elvis impersonator from Corinth, Mississippi, was charged with sending a threat to the president last week after letters containing the poison triggered security scares around Washington. But a preliminary hearing that had been scheduled to continue on Tuesday was canceled and Curtis was released.

There is a bond attached to his release, but the conditions of the bond are under seal at this point, said Curtis' attorney, Christi McCoy. She said her client has been framed by someone who used several phrases Curtis likes to use on social media. "I do believe that someone who was familiar and is familiar with Kevin just simply took his personal information and did this to him," McCoy told CNN. "It is absolutely horrific that someone would do this."
