TUPELO, Miss. (AP) -- Charges of sending ricin-laced letters to President Barack Obama and others were dropped Tuesday against an Elvis impersonator from Mississippi who has said since his arrest last week that he had nothing to do with the case.
Meanwhile, in Tupelo, numerous law enforcement officers, including some in hazmat suits, converged on the home of another Mississippi man, Everett Dutschke. At around 11 p.m. CDT, they concluded a 10-hour search of the man's property and nearby ditches and culverts. Investigators declined to say afterward what if anything they had found.
No charges have been filed against Dutschke and he hasn't been arrested. Both Dutschke and 45-year-old Paul Kevin Curtis, who had faced charges in the case, 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.
Referring to officials' questions for him about the case, Curtis said after he was released from custody Tuesday afternoon, "I thought they said rice and I said, 'I don't even eat rice.'"
"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," Curtis added.
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.
The dismissal is the latest twist in a case that rattled the country already on edge over two deadly incidents, the Boston Marathon bombing and the plant explosion in West, Texas.
Curtis was well-known to Wicker because he had written to the Republican senator and other officials about black-market body parts he claimed to have found while working at a hospital -- a claim the hospital says is untrue. Curtis also wrote a book called "Missing Pieces" about his claims and posted similar language on his Facebook page and elsewhere. The documents indicate Curtis had been distrustful of the government for years.
He told The Associated Press Tuesday that he realizes his writings made him an easy target.
"God will get the glory from here on out. It's nothing about me. It's nothing about my book. It's nothing about the hospital. After 13 years of losing everything I have turned it over to God. After all these years God was the missing piece," Curtis said.
The two men the FBI are investigating are not strangers. Dutschke said the two had a disagreement and that the last contact they had was in 2010. Dutschke said he threatened to sue Curtis for saying he was a member of Mensa, a group for people with high IQs.
Since his arrest at his Corinth home on April 17, attorneys for Curtis say their client didn't do it and suggested he was framed. An FBI agent testified in court this week that no evidence of ricin was found in searches of his home.
Dutschke (DUHST'-kee) said in a phone interview with the AP that the FBI was at his home for the search connected to the mailings. Dutschke said his house was also searched last week.
"I don't know how much more of this I can take," Dutschke said just before 7 p.m. CDT, as investigators continued to comb his house.
Curtis attorney Hal Neilson said the defense gave authorities a list of people who may have had a reason to hurt Curtis.
"Dutschke came up," he said. "They (prosecutors) took it and ran with it. I could not tell you if he's the man or he's not the man, but there was something there they wanted to look into."
An FBI intelligence bulletin obtained by the AP said the two letters to Obama and Wicker said: "To see a wrong and not expose it, is to become a silent partner to its continuance." Both were signed, "I am KC and I approve this message."
Multiple online posts on various websites that could be seen by anyone under the name Kevin Curtis refer to the conspiracy he claimed to uncover when working at a local hospital from 1998 to 2000. In one post, Curtis said he sent letters to Wicker and other politicians. He signed off: "This is Kevin Curtis & I approve this message."
Curtis attorney Christi McCoy said she doesn't know what new information prosecutors have and that the plot to frame her client was "very, very diabolical."
