Federal authorities have scant evidence linking a Mississippi man to the mailing of ricin-laced letters to the president and a senator, his attorney says.

Christi McCoy said after a court hearing Friday that the government has offered no evidence to prove her client, Paul Kevin Curtis, had possession of any ricin or the seed from which it is extracted — castor beans. An FBI agent testified during the hearing that he could not say if investigators had found ricin at Curtis’ home, and McCoy said the evidence linking the 45-year-old to the crime so far has hinged on his writings posted online.

He is adamant that he did not do this, and she said she has seen nothing to prove him wrong.

Curtis was ushered into the courtroom before the hearing began in an orange jail jumpsuit and shackles. He turned to face a young woman in the audience before the hearing and whispered, “I didn’t do it.”

Prosecutors had wanted to delay the hearing because searches of Curtis home and car had not been completed and DNA and other tests are pending.

Curtis’ brother Jack Curtis and 20-year-old daughter Madison Curtis watched the court proceeding and said afterward they are not convinced he did what he is accused of, even though they tried to keep an open mind about what would be presented.

“After hearing what I heard in this courtroom, it appears to me that the reason I haven’t been provided any evidence is there appears to be none that would link my brother directly to the charges that have been made,” Jack Curtis said after the hearing.

So far, Curtis is the primary focus for investigators and the only person arrested in connection with sending those letters and a third threatening letter mailed to a judge. But during a hearing Friday, FBI agent Brandon M. Grant testified that authorities were still trying to determine whether there were any co-conspirators.

As the hearing went on for roughly two hours, Grant said under questioning by Curtis’ attorney that he could not say whether any ricin had been found at Curtis’ home because the investigation was ongoing. Investigators had found a package they were interested in, but Grant said he did not know what was in it.

Grant also testified that there was one fingerprint on the letter sent to the judge, but that it didn’t match Curtis. He said several people handled the letter, and DNA and other tests are pending.

Curtis’ lawyer peppered the agent with questions in an attempt to show the government had little hard evidence, but Grant said people’s lives were at risk and it wasn’t like a fraud investigation in which authorities could gather more evidence before making an arrest.

Family and acquaintances have described Curtis as a caring father and enthusiastic musician who struggled for years with mental illness and who was consumed by trying to publicize his claims of a conspiracy to sell body parts on the black market.

Curtis is an Elvis impersonator and performed at parties. Friends and relatives also say he
