    communicating the validated request from the tracker server to the plurality of wireless networks of different communications carriers to collect geographic coordinates at which the wireless communications device is located;

    collecting, from two or more of the wireless networks, two or more sets of geographic coordinates of the wireless communications device;

    processing the two or more sets of geographic coordinates to identify an average set of geographic coordinates;

    communicating the average set of geographic coordinates of the wireless communications device from the tracker server to the government agency server;

    repeatedly collecting and communicating the geographic coordinates;

    stopping, collecting and communicating the geographic coordinates in response to receiving a request to stop collecting the geographic coordinates; and

    storing the average set of geographic coordinates in a storage unit in communication with the government agency server and not in direct communication with the tracker server.
