Thanks, RickshawFan! I hadn't checked this thread for several weeks so I wasn't aware that our great mmarty was back!
Harmon sounds like a good possibility.
One thing about motorcyclists is that they would never dream of being without their motorcycles! It is in their blood, IMO. Maybe he had a motorcycle at the site and whoever had stolen that car left nearby took it? OR did the motorcycle break down and our unidentified person had maybe taken the car left nearby?
I have to go back and get my information right. Some of the circumstances have now escaped me.
Glad to see this thread moving again!
I'm thinking he could have been killed offsite, dismembered, and then delivered to the dump site. Or your option and Carbuff's where the perp came in the car, the UID on the motorbike, and the perp drove away with the motorbike. This would have had the added advantage of making everyone associate the car with the UID and not with the perp, which might easily send an inquisitive sleuth off track.
If the perp brought the body in the car and then left the car, the perp would have needed a ride to get back to town.
Good thought about motor bikers not wanting to be separated from their bikes. The scenarios in the previous paragraph would have the UID with the bike until the killing.
I'm thinking the UID might have been on the outs with his biking gang and went into hiding. They found him and killed him, then cut off his hands instead of pulling off his rings, filet-ed his tattoos, and grabbed his jacket and boots. (Gotta have boots if you're a self-respecting hard core biker. Forget the Walmart brothel creepers, which seem to pretty much describe the shoes found at the scene.)
Brief aside....The shoes that were found at the scene and were too short for the owner....could this be from driving? If used for walking, they'd be crazy blister-y. You wouldn't notice this as much driving because your feet point to work the accelerator?
The feet were missing on the UID because the perp couldn't get his feet out of the boots (maybe rigor mortis had set in), and so he simply cut the feet off? This would put the cuts somewhere up the shin from the ankles? Speculating.... (I bet motorbike boots are hard to get off and on even when you're the owner.)
The dog is confusing. I have seen dogs on motorbikes though.....And the dog sighting might be irrelevant, e.g. the dog belonged to someone else entirely, came across the body and tried to get help or just needed some store-bought food. Lots of possibilities....
I had some thoughts about the "campsite that is not a real campsite" and how it relates to the killing.
I'm thinking this is what is known as "dispersed camping", i.e. random sites in the woods, for free. It doesn't sound as though the UID actually camped there (they would have found micro-trash or cigarette butts, or something that wouldn't have been removed by animals or humans), but I can't imagine what he might have been doing there except a sudden trip to lay low. It also sounds as though it's an unlikely place to pick for a meeting: it seems to me if the killing happened there the perp followed the UID to that location.
But it is curious that no one found the body sooner, unless it was covered by snow quite soon after the murder and then reappeared in the spring after snow melt. Are we sure it wasn't moved there in the spring after being stashed somewhere else for the winter? No doubt we've been told this already, but I'm putting this out there again. (Now I recall, maybe the paint-splattered moving blanket was used to carry the body?)
"Dispersed" camping is sometimes used by folks who want to lay low or who don't want to pay rent for a while or can't afford a campground or are half way up a mountain. I would guess this site is not someone's vacation spot, since it doesn't sound very attractive. Dispersed camping is legal on much of USFS and BLM land. There's no real oversight. But a body in the summer out in the open should have been seen by someone sooner looking for a "dispersed" camping spot, IMO, especially since this one seems quite accessible.
I can't figure out this dump spot at all. Makes no sense. Why there? And why did someone imagine it would be a good idea? Of course, it worked out, but IMO this was luck and very chance-y.
