Authorities have charged a Mississippi man with making and possessing ricin in the investigation into poison-laced letters sent to President Barack Obama and others.
U.S. attorney Felicia C. Adams and Daniel McMullen, the FBI agent in charge in Mississippi, made the announcement in a news release Saturday following the arrest of 41-year-old James Everett Dutschke.
FBI spokeswoman Deborah Madden said Dutschke was arrested about 12:50 a.m. Saturday at his house Tupelo.
The letters, which tests showed were tainted with ricin, were sent April 8 to Obama, Sen. Roger Wicker of Mississippi and 80-year-old Mississippi judge Sadie Holland.
Dutschke is expected to appear Monday in U.S. District Court in Oxford, Miss.
He faces life in prison if convicted.
His lawyer said in a text that she had no comment.
