The 71-year-old manager of a Springfield store was arrested and charged in federal court for distribution of synthetic cannabinoids. 

Letha Dean of Salisbury was arrested by U.S. Marshals on April 13 for intent to distribute a controlled substance. Dean is the eighth person arrested as part of a continuing task force investigation into the sale and distribution of synthetic cannabinoids in Central Illinois. 

Dean worked at a store called Mystic Enchantments in Springfield. An undercover officer met with Dean and purchased 520 packets of suspected synthetic cannabinoids, federal prosecutors said. Agents then arrested Dean and searched the store, where they found 1,445 more packets in a back room. 1,967 packets weighing more than 26 pounds were seized from the store. 

Several men also face synthetic cannabinoid-related charges in the Decatur area in a different investigation.
