Daniels eventually filed simple assault charges and he said the judge who handled the case was Sadie Holland — one of the three people who received a letter suspected of containing ricin, according to authorities. Records show she sentenced Curtis to six months in the county jail.
Daniels was an assistant district attorney at the time. "He launched a smear campaign against me, saying I attacked him and tried to shoot him," Daniels said Thursday.
"It made my life miserable for almost two years, having to deal with this guy," he said.
On Thursday, North Mississippi Medical Center confirmed Curtis' employment and said in a statement he was not terminated in response to allegations about the facility.
Under the name Kevin Curtis, multiple online posts describe the conspiracy Curtis claimed to uncover when working there. The posts say the conspiracy began when he "discovered a refrigerator full of dismembered body parts & organs wrapped in plastic in the morgue of the largest non-metropolitan health care organization in the United States of America."
The hospital's statement says it works with an agency that specializes in harvesting organs and tissue from donors, and then immediately transports those organs for donation. The hospital says it does not receive payment for the donated organs.
In one post, Curtis said he sent letters to Wicker and other politicians.
"I never heard a word from anyone. I even ran into Roger Wicker several different times while performing at special banquets and fundraisers in northeast, Mississippi but he seemed very nervous while speaking with me and would make a fast exit to the door when I engaged in conversation ... "
Wicker said Thursday in Washington that he had met Curtis when he was working as Elvis at a party Wicker and his wife helped throw for an engaged couple about 10 years ago.
Wicker called him "quite entertaining" but said: "My impression is that since that time he's had mental issues and perhaps is not as stable as he was back then."
Early Thursday evening, the FBI said lab tests confirmed the presence of ricin in the letters mailed to Obama and Wicker.
At least a dozen armed officers wearing gas masks and hazardous-material suits went into Curtis' home Thursday evening in Corinth. There was no immediate word on what they found inside.
Police had blocked off the home with crime-scene tape since Wednesday's arrest. No neighbors have been evacuated.
Raymond Zilinskas, a chemical and biological weapons expert at the James Martin Center for Nonproliferation Studies in California, called the process to make ricin elaborate. He said it would not be difficult to create a low-concentration version using instructions from the Internet, but a finer and more concentrated version would require laboratory equipment and expertise.
Laura Curtis said she doesn't think her ex-husband has the knowledge required to make ricin. She said he collects a monthly disability check, and she did not know where he would get ricin.
She said she cried when she heard about the arrest.
"It's more sinking in today, because you see the longer picture," Curtis said. "It's just me and the kids."
