Would agree with your reasoning, but allowing the phone to go along for the ride doesn't lead me to believe that this cat is intelligent or experienced. I think the route is telling - in the sense that he circled back around. He had somewhere to be for an alibi, IMO, and not too awful far from the scene of the crime (re: same city/county). A budding predator? Perhaps. Was he one at the time? Not likely.
We also are giving him too much credit. The fact is that if the crime scene would not have been corrupted by hundreds of folks stomping on potential evidence, there would likely have been some solid forensics obtained. Also - had Clint got his shotgun like he was told to do, this guy would be under a gravemarker right now. Not very calculating if you ask me.
Finally - if he is or has become a serial predator, he has clearly moved on. and committed other crimes There would be enough victims by now for a forensic pattern to show. I'm not talking a pattern like that one dudes illogical 'young blonde' theory either - I'm talking about solid evidence of a repeat offender.
Remember experienced psychopathic predators will consistently do the unexpected. They all seem to have another self behind their mask of normalcy. This other self's thought pattern and actions are 180 degrees from that of a normal person's.
Tonto, in every case involving an experienced sexual predator/serial killer, there will always be this comment; 'I think we are giving him too much credit'..
If the full camouflage perp was turkey hunting, Clint would have noticed a shotgun during the altercation..The hunting attire was only a ruse; a means to an end..
Three reasons for full camo, imo..(Full camo includes cape, coveralls, & gloves. Coveralls can be removed very quickly to change clothing and the clothing description, analogous to a chameleon. )
Forensics/DNA contamination prevention(analogous to an encapsulated suit used by CSI)
Camo is normal attire worn during turkey season in many rural areas/blend.
The perp that abducted Holly was not only brazen and experienced, but very lucky, imo...
RE: Finally - if he is or has become a serial predator, he has clearly moved on. and committed other crimes
Imo, he did move on, and has taken other unsuspecting innocent victim/s...
