The whole GPS thing has me thinking that they found a Garmin or Garmin GPS files on his computer that take him directly there to that spot in Pala. If this guy was a hunter or fisherman, or even was somewhat active outdoors, having a Garmin would be THE thing to have, gadget-wise and it gives EXACT locations, unlike the iPhone, which has GPS but it isn't quite like the Garmin.
Either way, I feel very strongly that they either found something very exact that led them there OR he made a plea. I just cannot wrap my mind around this 'coincidence' because it just doesn't seem plausible.
I have no idea what it is most of you have against coincidences.
