I’m not understanding where the clearly seen comes in? There’s a wooded area between the gravel road & the creek. If the van gets to the house first, it’s even further away & more woods. I also don’t recall anyone stating whether the van was seen or heard (hard to sneak down a gravel lane in a vehicle) but I could be mistaken. Just about every part of the crime was brazen - middle of the day, people on the trails, van shows up, clothes strewn along the creek, running down the road muddy & bloody.
Just trying to see through your eyes, not arguing.
