JACKSON, Miss. - A dust mask and other items seized from the martial arts studio of a Mississippi man charged with sending poison-laced letters to President Barack Obama and two other public officials tested positive for ricin, according to a court document released on Tuesday.
Records seized by the FBI also showed that Tupelo martial arts instructor Everett Dutschke ordered castor bean seeds, used to make ricin, from eBay, FBI Special Agent Stephen Thomason said in an eight-page affidavit.
Dutschke is expected to appear in US district court in Oxford, Mississippi, for a detention hearing on Thursday.
Contacted by Reuters, Dutschke's attorney, public defender George Lucas, declined to comment.
Soon after the seeds were delivered to Dutschke's home address, someone using his laptop computer downloaded a publication on safe handling and storage of the poison, Thomason stated.
