Now that additional information has come out, it is pretty easy to understand what happened to Jerold.
He was separated from his mother at the campsite along forest road 241. Somehow he managed to find his way back to forest road 241 and started walking east, AWAY from the campsite. He may have walked through the forested area for awhile before he found road 241 again.
While initially searching for him, his family may have been concentrating on the area between the campsite and the main road to it, which would be to the west of the campsite. As they were concentrating on the immediate area, Jerold was walking further away down road 241, or in that direction.
He walked and walked and walked and walked down road 241, about 6 miles all together. His fatal mistake was when he made a left turn onto forest road 240. This would have been a lightly traveled primitive road which is really only suitable for 4 X 4's and ATV's. He continued walking down this road until it dead ended.
The timeframe in which he did all of this is unknown. It's very obvious that he could have easily slipped out of the initial 2 mile search zone rather quickly. By the time LE arrived, he may have already been well beyond the 2 mile search radius. Keep in mind, LE and the parents had no idea which direction to look, so they were forced to look in ALL directions, 3 of which were wrong. As they continued to fan out around the campsite, Jerold continued to walk down the 241 road.
None of us know how long this journey took, or if he walked this road 241 in the dark, or how many times he stopped and circled back. He at least had the presence of mind to stay on or near the main road. That area is heavily forested and the terrain is rocky and a burden to hike around on. Staying on the main road would be much easier and safer.
Keep in mind, when I refer to the "main road", I'm talking about the forest road 241. This is an unmaintained road that is lightly traveled. These roads are not anything like the nice smooth gravel roads like you may find on the drive to grandma's house in the country. They have rocks jutting up, low spots, soft spots, huge mud puddles, uphill climbs and downhill drops.....and all that in a one mile stretch. Many times you have to literally crawl along in a full sized pickup, unless you don't care about tearing up the suspension on your vehicle. Many of these roads aren't much more than glorified game trails. I suspect that forest road 240 was an even rougher road than 241, simply because it would have rarely been traveled by anyone other than ATV enthusiast and hunters. This may well have been why Jerold ventured down it......he was following tracks.
He would have had NO access to water, there are no signs of civilization in that area, and it would have been pitch black dark at night time.
In my mind, the worst part about this is the fact that had he continued to walk down forest road 241, rather than taking 240, it would have dumped him out right there at the main highway to the Grand Canyon. Just another 2 miles on 241, and he would have heard and seen cars passing by on the paved highway. He was that close.
Below is a map I made up late yesterday showing where he was found and how he got there. The first 6 items on the menu are what I added. The other items below are things I was noting before he was found, such as the location of watering holes.
Recap: He walked along road 241, he took a left at road 240, and he was eventually found somewhere towards the end of road 240 where it dead ended. He was found approx. 4 miles in a
straight line from the campsite, which equates to around 8 1/2
drivng/walking miles.
