During the FBI’s ongoing investigation into letters containing ricin addressed to President Barack Obama, Senator Roger Wicker, and a Mississippi judicial official – Sadie Holland – evidence collected by the FBI from the former business, Tupelo Taekwondo Plus, located on Rankin Boulevard Ext. in Tupelo, Mississippi, tested positive for trace levels of ricin.
Because public safety is always the FBI’s first priority in any investigation, that location was immediately sealed off and appropriate public health authorities were notified. The FBI is now conducting further forensic examination for the purpose of identifying trace evidence, residues, and signatures of production that could provide evidence to support the investigation.
Ricin is a poison found naturally in castor beans. Ricin poisoning can occur when the substance enters the body through ingestion, inhalation, or injection. To date, the FBI is not aware of any illness as a result of exposure to these letters.
