It seems to me that the part he *did* plan, the actual abduction, went perfectly for him. The failure was in the second part, which was keeping her. So if you look at it as two things, the first was indeed well planned and executed. The second, not so much and I think it's because he never thought beyond the "getting" and made good plans for the "keeping" MOO
I hope it's acceptable to wonder WHY he didn't plan well for her presence in his house somewhere.
As I think back on the things a Sociopath will do, one is to mimic actions usually from a movie or TV.
Maybe today, a video game.
Perhaps he had seen movies which showed someone storming a door ( SWAT team, the Marines) whatever, and that was the primary part of his criminal mind set, not that it was the GOAL, because abducting Jayme was, but that he was able to " recreate" the fantasy of kicking and shooting a door in easily.
Since he'd never BEEN a caregiver to any person as far as we know, and because I do not think a Sociopath can even THINK in terms of " What will ANY OTHER person need?" or " What will I need to do for this, that and the other thing that may come up?" this may have been his " troublesome area".
He does not discuss or describe much except the haphazard moving of a child sized bed and putting things which were already IN the house around the floor space to keep Jayme in the confined space.
This is something I can see siblings doing as game play OR maybe in anger to actually pin the other one in at around age 8-10. The dumbells and weights being the difference of course, but the larger, heavier child could have used something the younger child couldn't move in the same manner of weights.
We have the info from both Jayme and JP that music was played in his room and Jayme seemed to indicate it was for hours a day. She THOUGHT he had company over every day, lots of people coming and going.
I don't think so. I don't think he's EVER had much but an apparently persistent family or family member coming and going as they pleased since he became the lone tenant.
He was trying to look like a busy man, an important man with MANY FRIENDS, when he'd never been that or had that.
Why would he do so? Probably the sense of " What the movies showed about 21 year olds having friends over every evening and all weekend, in and out, parties etc". He almost certainly did NOT ever have those networks and relationships.
I think he wanted to play some sort of game for hours every day, and DID have some type of Internet access and a device to play on. Maybe it's not been mentioned by him because it wasn't HIS. Also, he stole gas from neighbors. If neighbors who lived close to him had home networks set up with relatively poor security, he could have hacked into their systems and played his game and they would never have known in certain types of internet connections and user preferences.
The other part is the incongruity. " I shot him in the face and he fell". I turned slightly and fired at her, hitting her in the head" which is true, we have every reason to believe, to " I played video games on a stolen tablet while J.L.C.was stuck underneath my old childhood bed for hours every day".
I think he didn't want to change ANYTHING about the things he liked to do in life, whatever horrible things we may or may not find out, and he planned so poorly that he truly could not support the daily captive life like a " real" kidnapper in a movie would have..
He said he hit the wall and screamed to scare her a couple of times. That is AWFUL for her, but it's a stark contrast to the PLANNED violence of what he'd just done to her parents.
