James Everett Dutschke, 41, will appear in a Mississippi court Monday, two days after being arrested and charged with mailing letters laced with the poison ricin.
Dutschke's arrest came after the April 23 release of Paul Kevin Curtis, 45, an Elvis impersonator with a history of mental illness. Curtis was arrested April 17 after letters sent to President Barack Obama, U.S. Sen. Roger Wicker, R-Miss., and Mississippi judge Sadie Holland tested positive for ricin earlier this month.
"I am KC and I approve this message," the letter to Obama said, ABC News reported. The phrase was reportedly used by Curtis, who believes he uncovered an organ-harvesting conspiracy at a Mississippi hospital.
The charges against Curtis were dropped after a search of his home and car revealed no evidence of ricin or castor beans, which are used to make the poison. An FBI agent testified in court that Curtis did not perform Internet research on making ricin, based on a search of his computer.
Dutschke's home was searched last week, after Curtis was released.
Curtis's attorney, Christi McCoy, told The Associated Press on Saturday: "We are relieved but also saddened. This crime is nothing short of diabolical. I have seen a lot of meanness in the past two decades, but this stops me in my tracks."
Judge Holland, the AP reports, is a common link between the two men. She sentenced Curtis to six months in jail for the 2004 assault of a local attorney, and Holland's son, a state representative, was challenged in a 2007 election by Dutschke.
The Wall Street Journal reports that the two men were involved in a feud over Curtis's allegations of organ harvesting and Dutschke's refusal to print them in a local newsletter. Curtis's brother told the Journal that Dutschke then attempted to scuttle the Elvis impersonator's musical gigs.
Before his arrest, Dutschke told The Northeast Mississippi Daily Journal that his last interaction with Curtis was in 2010, when the men engaged in a testy email exchange over Curtis's allegedly fake membership certificate from Mensa, an organization for people with high IQ scores.
Dutschke worked as a martial arts instructor and in January was charged with molesting three girls under the age of 16, according to news reports. He is awaiting trial on those charges.
According to a news release from the U.S. Attorney's Office of the Northern District of Mississippi, Dutschke is charged with "knowingly developing, producing, stockpiling, transferring, acquiring, retaining and possessing a biological agent, toxin and delivery system, for use as a weapon," which carries the possible sentence of life in prison and a $250,000 fine.
