Ricin Letters Case Heading to Grand Jury

A grand jury in Mississippi will hear the evidence against James Dutschke, the man suspected in the mailing of letters laced with the poison ricin to President Barack Obama and others.

A judge today ruled that there's enough probable cause to send the case to a grand jury.

An FBI agent testified today that a dust mask that tested positive for ricin also contained DNA from Dutschke.

Dutshcke was arrested Saturday. He is suspected of sending the poison-laced letters to Obama, U.S. Sen. Roger Wicker and a Mississippi judge.

Dutshcke's attorney waived a detention hearing, so he will remain behind bars. He has previously denied sending the letters.
