Another hypothetical discussion stimulator!

The “children wandered into woods or road” option.
When I try to open my mind to the possibility that the children wandered into the woods, or to the roadside, I stumble over a lot of mental roadblocks.
Right away, I am troubled that the children were able to open the sliding door, as these are often heavy. I’m also troubled that it had apparently been a problem but the parents hadn’t come up with a fix, like a lock, or a bell on the door. I’m also troubled that this was the ONE time the kids had managed to close the door, as DM stated he’d yelled at them several times for leaving it open. But assuming the parents are truthful, and the children had gone silent for about 20 minutes, they would have had to be moving very very fast to get as far as they apparently have. This requires me to believe these kids, as soon as they made it out that sliding door, booked it as fast as they could. I have a hard time picturing children that small to be that motivated to get out of the yard and far away, that fast. The parents said the children had gotten out the sliding door before, but they certainly didn’t say anything about the children attempting to make a run for the woods or the road, not anything beyond playing in the yard.
But - If they went into the woods, the terrain would make it hard to get far. I just don’t see 2 little kids agreeing to forge on through the dense forest, with fallen trees, flies, ticks, cold weather. It would stop being fun fast. But let’s say they did. They never dropped a single clue, and managed to elude DM, dozens of searchers, and trained dogs? I personally am amazed at the skill of search dogs, and if those children had gone into the woods, I think the dogs would have picked up on it.
Some have suggested little kids might hide if they’re afraid they’re in trouble. I don’t think 2 children this age, after hours out in a bug infested forest, cold, wet and hungry, would place fear of a scolding ahead of getting home to safety, warmth and food.
But what if they wandered to the roadside?
Here are 2 possibilities. Someone picked them up. Maybe someone who happened by, and saw their chance to harm the children, or sell them. I find the chance of this to be remote, just like the area they lived in is remote. The other option is one or both children were hit by a car. I have a personal hunch that many unsolved missing persons cases are the result of someone accidentally hitting someone with a car, panicking, and disposing of the evidence. So maybe someone hit one or both children. If the children did head to the roadside, I believe “hit by a car” is a more likely scenario than “abducted by a predator who happened by at the exact right moment”. I hope the trained dogs were taken a certain distance down that road in both directions, to sniff out the potential for an accident scene.
And that is my unpacking of the “wandered to woods or to roadside” scenario in this case. I pray they are found and if there is someone responsible, that they are found and justice is served.
All my own opinion and speculation.
