The two things he did in terms of
sloppy are abducting someone between work (Ledcor office in Reno) and home (Fallon), and allowing his truck to be connected with her car at Sherwin-Williams. Given that he was arrested at work at the office in Reno, and he lived in Fallon, I think it's quite likely that he first saw Naomi at the Fox Peak Gas Store in Fernley at 5 AM. She was there every morning, and it's a convenient place from him to get gas and coffee on the way to work.
I don't think she knew him, or even noticed him, but I think he started paying attention to her at some place like the Fox Peak store. One day, he would have decided to see where she went from the store - and learned that she sat in her car in a dark parking lot using her phone for 20 minutes every morning.
Referencing the video with the co-worker, did the co-worker say that Troy said he had to miss work on Monday because he had an "under-age girl" summons to deal with? Did Troy say that he'd been camping with "wife and kids" on the weekend (he has no family that we know of)?
Naomi was abducted on Saturday. When exactly was Naomi's car parked at Sherwin-Williams? Was it on Saturday or Sunday evening? Monday evening?
We know the truck headed East in the late afternoon. Saturday sunset was at 6 PM. When did he drop off her car? Where did he go next? Home? Did he return to the same location that he took Naomi? Was she still alive? Monday noon she was reported missing. Tuesday he was uncharacteristically 30 minutes late for work. Her car was found on Tuesday at noon. Maybe he dropped off her car on Monday evening, after employees left the building but before sunset, so he could be home for supper (??).
Just an opinion after watching this:
