LV would have almost certainly have disposed of the bodies within the first 2-3 hours after the murders, possibly even sooner imo. Remember that this wasn't a secured crime scene where LV could live out his fantasy as he would have undoubtedly liked to with the two young women, then spend unlimited time in body disposal. There were too many variables potentially at work that could have gotten LV busted red handed with corpses. He would have been in a pretty big hurry to get rid of the bodies and be back at the Theatre to tighten his only plausible alibi (slept all night, saw no one, knows nothing). This is what has leant me to believe that he used the river for disposing of Pearsall or possibly even dumped Pearsall separately but out in the same general area as K&B. Everytime I think about how this would have unfolded I just can't get past the rising fear/paranoia and stress that LV would have felt continuing to cruise around with 3 corpses in his vehicle. He wouldn't have felt comfortable enough imo to spend a significant amount of time planning body disposal. Pearsall was over six feet tall and weighed between 150-160 pounds. LV wouldn't have taken him up hill from the highway and risk being seen by a passing motorist. He would have taken the path of least resistance down the hill from the highway. It's entirely possible that he would have placed the body in a place that wasn't in plain sight but I don't believe he would have buried him. I think Pearsall's remains rest within roughly 100 yards or less from the highway on the down sloping side of the road. Likely at the bottom of a ravine or pretty good slope (to ease the dragging 150-160 pounds of dead weight) and possibly somewhere obscure, like under old growth bushes etc. I strongly believe that if Pearsall didn't end up in the river that he is with-in a15-20 mile stretch of the highway in that same Highway 3 region that the female victims were found in.
