Back to square one?
I originally thought they fell down a mine shaft, cave, hole where they were overcome by some toxic fumes or off a cliff.
To me, the dog in the truck could mean they met a person as they were leaving and went with him in his vehicle to make the final deal for the sale of the land with the money they had in the satchel.
I seem to remember a dog scenting near a water tower. I believe they could have been killed there and later dumped at the site where their remains were found.
