Denver Post:  “The details on the raids . . . come from an affidavit in the criminal case against Diaz and provide new context for the largest federal operation against medical-marijuana businesses ever in Colorado. Agents executed ‘approximately 15’ search warrants during the raids, the affidavit states. Sources have told The Denver Post that the raids — which a search warrant shows targeted 10 men — were part of an investigation into a single enterprise that detectives believe may have ties to Colombian drug cartels. . . . The raids focused especially on stores, cultivation warehouses and individuals connected to the VIP Cannabis dispensary in Denver.”
