The  FBI has dropped charges against the Elvis impersonator accused of sending ricin-laced letters to President Barack Obama.   45 year old Paul Kevin Curtis from Mississippi has said since his arrest last week that he had nothing to do with the case.

According to the Associated Press, law enforcement officials in Tupelo, including some in hazmat suits, converged on the home of another Mississippi man, Everett Dutschke.  Around 11 Tuesday night, they concluded a 10-hour search of the man's property and nearby ditches and culverts. Investigators declined to say what if anything they had found.

A.P. reports, no charges have been filed against Dutschke and he hasn't been arrested. Both Dutschke and Curtis, say they have no idea how to make the poisonous ricin and had nothing to do with sending them to Obama, U.S. Sen. Roger Wicker of Mississippi and a state judge.

A one-sentence document filed by federal prosecutors said charges against Curtis were dropped, but left open the possibility they could be re-instated if authorities found more to prove their case. Prosecutors were not immediately available for comment.
