Well of course, there would also be cell-phone records of gps coordinates on that day in October or that day that either a tissue sample was photographed with the cellphone if done on-site...... assuming he did take cellphone pictures. That would be material especially if the October 8th day is correct and verification could take place anywhere from repeater or tower in that remote of an area. Ultimately, I guess the big reveal will be more dependent on other samples than the Sierra sample.
