> Law enforcement made a number of controlled purchases during the investigation into Porras and his co-conspirators. The purchases and subsequent surveillance followed the same pattern every time: make a purchase; watch Porras drive to a storage facility where he stored product; follow Porras to the Post Office; talk to Postal Inspectors about the package Porras or his co-conspirator had dropped into a USPS Blue Box.
