(AP Photo/Northeast Mississippi Daily Journal, Thomas Wells, File) (Newser) – The case against the new ricin suspect is looking a lot stronger than the one against the old suspect. An FBI affidavit says investigators found traces of ricin at the martial arts studio once owned by James Everett Dutschke, along with traces on a dust mask tossed in a nearby trash can, reports AP. Dutschke also bought a key ingredient in the poison, castor beans, over the Internet, says the filing. The Tupelo man is accused of sending tainted letters to President Obama, Sen. Roger Wicker, and a local judge, and the 41-year-old faces life in prison if convicted.
