A Mississippi man charged with sending poison letters to President Obama, Sen. Roger Wicker and Mississippi Judge Sadie Holland was ordered held without bond at a Monday hearing.
Prosecutors are expected to describe what evidence they have against James Everett Dutschke at a Thursday hearing.
Authorities spent several days last week searching Dutschke's home and former business but have said very little about the suspect beyond a news release announcing the charge of making and possessing ricin.
Dutschke was brought to federal court in Oxford, Miss., wearing an orange jumpsuit with his hands shackled.
He said little during the brief hearing other than to answer the judge's questions about whether he understood the charges against him. He answered that he did.
Dutschke was arrested Saturday. An attorney from the public defender's office who has been appointed to represent Dutschke declined to comment after the hearing.
