OXFORD, Miss. - Federal authorities have produced 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 his daughter in the audience before the hearing and whispered, "I didn't do it."
FBI spokeswoman Deborah Madden said Saturday that she couldn't discuss what was found during the search of Curtis' home because it's part of an ongoing investigation.
So far, Paul Kevin 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.
