Traces of the poison ricin have been found on items and at a business that once belonged to Everett Dutschke, the Mississippi man arrested last week for mailing a toxin-laced letter to U.S. President Barack Obama.<br /><br />An affidavit states Dutschke's computer was used to purchase castor beans - the precursor to ricin - online.<br /><br />On April 22, investigators watching Everett Dutschke saw him dump objects in a garbage bin near his martial arts school. Among the items recovered were a mask, a coffee grinder and a box of latex gloves.<br /><br />Forensic officers also took evidence from his taekwondo school and traces of the poison were found on the mask and samples taken from the school. <br /><br />Documents from a printer owned by Dutschke also showed the same printing artifacts - unique to each printer - as were found on the toxic letter.<br /><br />Dutschke made a short court appearance Monday, but said little other than confirming he understood the charges against him.<br /><br />FOR MORE NEXT MEDIA ANIMATION, GO TO: http://www.youtube.com/subscription_center?add_user=NMAWorldEdition <br /><br />FOR MORE NEXT MEDIA ANIMATION IN ENGLISH, GO TO: http://www.youtube.com/subscription_center?add_user=NMAtv <br /><br />FOR MORE TOMONEWS US, GO TO:<br />http://www.youtube.com/subscription_center?add_user=TomoNewsUS <br /><br />FOR MORE TOMONEWS JP, GO TO: http://www.youtube.com/subscription_center?add_user=TomoNewsJP <br /><br />FOR MORE APPLE DAILY ENGLISH, GO TO: http://www.youtube.com/subscription_center?add_user=AppleDailyEnglish <br /><br />CHECK OUT THE ODDBODS!<br />http://www.youtube.com/user/nxTomo
