New here so forgive me if I’m making mistakes. I lived in the area for several decades and also volunteered on the fire department with Carey Mae Parker’s dad before he passed away. The area where a bike and remains were found is close to where the MC family used to live.
Just throwing this theory out because this is the part that keeps jumping out at me quoted from the Discovery Site:
Did This 70-Year-Old Grandfather Stage His Own Suicide, Or Was He Murdered?

I think it’s possible MC drove to the location, his truck was taken back to his house by someone else, the blood splatter staged, truck left at the house and the bike was rode by that someone else back to the area. The only thing that isn’t clear is when did the Walmart stop happen. If it was after his first trip to the 2 mile bridge then my theory is no good.
