All of the items and swabs taken in the two studios tested positive for ricin. Agents also found records indicating Dustchke had ordered castor bean seeds through eBay late last year. Castor beans are the source material for ricin, which can be deadly, especially when inhaled.
In hindsight, officials could have surmised back in January that Dutschke was up to something. On Jan. 18, pursuant to his arrest on state charges of child molestation, his computer and hard drives were subject to a full search by police. At that time, officers uncovered two publications downloaded on Dec. 31, 2012: One was called, “Standard Operating Procedure for Ricin,” and the other, “Immunochromatography Detection of Ricin in Environmental and Biological Samples.”
Dutschke was arrested April 27 and is scheduled to appear in an Oxford, Miss., courthouse on Thursday morning.
