The attorney for a man accused of mailing ricin-laced letters to the president and a senator says federal authorities have scant evidence linking her client to the crime.
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.
FBI Agent Brandon M. Grant testified during the hearing that he could not say if investigators had found ricin at Curtis' home. McCoy says the evidence linking Curtis to the crime so far has hinged on his writings posted online.
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.
