7 On 19 May, the day referred to in the indictment, the controlled delivery was made. Immediately afterwards Nguyen telephoned the offender and said to her, "I stay over here unloading the stuff and then I'll head back, all right." Once the foot spas were finally delivered to their destination the offender, using her mobile telephone sent further text messages to that number in Canada confirming that delivery had occurred. They then left the hotel where they were staying and went to the storage facility. Contained within the storage facility was a listening device that had been put there by the authorities. Once the offender and Mr Nguyen entered that particular storage unit there, authorities were able to hear through the use of the listening device, saw-like sounds as Nguyen and Pham attempted to break through the bases of the foot spas. It is apparent that they had some difficulty doing so because later on Mr Nguyen went to a hardware store and purchased a number of tools. Later, the offender and Nguyen went back to the storage unit and continued to work removing the contents of the foot spas. The offender received instructions as to how the foot spas should be dismantled, following which conversation was recorded in which the offender spoke to Nguyen about where they should be looking within the foot spas for the concealed packages. In that conversation the offender said that she would participate in the work by doing some chiselling.
