So I guess out of all the video LE pulled, they found nothing?!
If this is true, I can't help but think he went on the trail. But I can't believe there's enough booze that would have made him take the dangerous path at night?
If for some reason he was mugged and hurt by a camper, would they realize the value of his credit card? He had cash on him but would that be enough?
Did they get his phone records? Could he have called someone while on his way out of the apartment to come pick him up that night?
Depending on the conversation he had with his gf, why would she try to immediately call him? Why not go back to bed, hope he sleeps it off and talk to him in the morning. Was she afraid he'd hurt himself or did she really think he'd walk on the river trail?
