From the Associated Press:

A court filing says charges have been dropped against a Mississippi man accused of sending ricin-laced letters to President Barack Obama and others.

The one-sentence document was filed Tuesday, hours after Paul Kevin Curtis was released from custody. The document says the ongoing investigation has revealed new but unspecified information.

An FBI agent had testified in court that no evidence of ricin was found at Curtis's home.

Meanwhile, authorities searched Tuesday at the home of another Mississippi man in connection with the case.

According to the Clarion-Ledger, authorities are now focusing on J. Everett Dutschke, a disgraced former GOP politician. Federal authorities reportedly searched his home on Tuesday as they tried to find a link to the ricin letters. Dutschke apparently operates a taekwondo studio in Tupelo, Miss.

However, Dutschke also ran for county commissioner in 2008 as a Democrat in Lee County, Miss.,  J.D. Griffin of the Mississippi Republican Party told TheBlaze in an email Wednesday. So, the last time he ran for public office, he did so as a Democrat, Griffin said.

More from the Clarion-Ledger:

Dutschke, 41, of Tupelo, who is currently the subject of a child molestation investigation by the Tupelo Police Department and the Lee County Sheriff’s Department, adamantly claims that he has nothing to do with the letters attributed to Paul Kevin Curtis, who was released on bond before lunchtime today.

The bloggers over Lady Liberty 1885 have done some additional research on the new ricin letter suspect. Apparently Dutschke, like Curtis, also considers himself a "performer." Take a look:

The bizarre case of a Mississippi man who is accused of sending ricin-laced letters to Sen. Roger Wicker (R-Miss.), President Barack Obama and a Mississippi justice official is not anywhere close to over it appears. The accused, Kevin Curtis, was released from detention on Tuesday.

In an interview with CNN on Tuesday, the suspect's attorney, Christi McCoy said the case has not been dismissed even though her client's preliminary hearing was cancelled and he was released from custody.

The attorney said Curtis has not been released to the "general population" but argued he was not a threat to the public at all.

“You’re saying he’s the wrong guy?” CNN's Chris Cuomo asked.

“I have a client who is not only not guilty, he is truly 100 percent innocent... I do believe that the government did what they believe was in everyone – everyone’s best interest because of where the evidence pointed at that time,” McCoy replied.

Confirming information found in previous reports by TheBlaze, McCoy said Curtis is an "activist" and is concerned about the tissue donation industry. Curtis has alleged a massive conspiracy involving organ harvesting across the United States.

Curtis became a suspect in the ricin scare after police discovered his signature on social media outlets, which matched the signature on the ricin letters. It read: "I am KC and I approve this message."

However, McCoy said police found no evidence of Curtis' involvement in their search of his home.

“You think somebody was trying to frame him?” Cuomo asked.

“I absolutely do,” McCoy confirmed.
