When you look at the map, the truck being found so car northeast seems inconsistent with where the location of part of his remains were found. Especially with the remains being found closer to his house and the truck not being near the river. That seems like someone was driving his truck after or during his death.
It would be nice to see the timeline of the weeks and days leading up to his disappearance being listed in the timeline.
-His day began at a worksite near McKenzie Bridge. This was twenty-three miles from his home. He left work around 9:30am to go home
-His truck was found at a popular place for mushroom hunting
-He left his tools plugged in and had plans to meet with a subcontractor so it seemed he would return to the job site
