A former martial-arts instructor from Tupelo, MS., is now charged with making  ricin and putting the poison in letters sent to President Barack Obama and two other public officials.

The FBI charged James Everett Dutschke, 41 on Saturday, days after dropping similar charges against an Elvis impersonator who insisted he had been framed. Coincidentally, the two men know each other and each has claimed being set up by the other.

Dutschke’s house, business and vehicles in Tupelo were searched earlier in the week  by crews in hazardous materials suits.

A news release from the FBI said, Dutschke was charged with “knowingly developing, producing, stockpiling, transferring, acquiring, retaining and possessing a biological agent, toxin and delivery system, for use as a weapon, to wit: ricin.”

Dutschke already had legal problems. Earlier this month, he pleaded not guilty to two child molestation charges involving three girls under age 16. He was  also appealing a conviction on a separate charge of indecent exposure.

The letters, tainted with ricin,  were sent on April 8 to President Obama, Sen. Roger Wicker of Mississippi and Mississippi judge, Sadie Holland.
