Bed fabric fold explanation versions

Bounced back on the recent bed's analysis. Reposted from commenting on another thread and added speculation.

DISCLAIMER: I AM NOT AN FORENSIC EXPERT

Screenshot copied from another thread

Reconstructed version for explanation of the outline, imprint on the fabrics if the last who touched the bed and fabrics were the perp.

Movement of the fabric in connection to directly moving/taking victim's body.

This shows three distinct pressure points on the bedsheets and extremely crumpled pink pajamas (nightgown?). This scene is violent and peaceful at the same time, as we can see the folded duvet. Could something more than only subduing happen in this room, before JB had been taken to the basement?

Other manipulation with the fabrics on and near bed. The Christmas pajamas are moved after moving the duvet.

Careful movement of duvet on the right side. Forceful pushing of the Beauty and the Beast pillow (it's also crumbled on the side near Christmas pajamas) and the duvet on the left. Why movement on both sides of the bed? Did the perp lifted and then pushed the duvet and pillow (yanked) to the right side, or was the victim placed there after being taken from right side?

The bottom of the bed could've been disturbed during the taking. There is unmarked possible foot placement at the very bottom, as arrows are facing different directions there too.

Taking of the victim from the right side of the bed

Perp's dominant hand likely is the right (if the video/crime scene photo is not flipped). Right hand placed higher - for precision (holding head/neck/mouth). It was placed first (1st pressure point). Left hand - for heavy lifting (center of gravity of the victim's body around the waist) placed lower, (2nd pressure point), folds over the top fabric folds.

The victim at this point was subdued, so it explains lack of small wrinkling on the fabric, esp. if she was wrapped into a blanket.

Lifting of the victim

At the lifting point, knee on bed creates most pressure, it pulls the blanket's fabric from the left side.

Afterward's (or before) the victim might've been placed on the left side of the bed - on the folded duvet and pillow, like mentioned. Possibly, due to struggle.

However, other versions are possible:

1. The "knee" (most pressure on the fabric) migt've been kidnapper's buttocks print, and something also was lifted and taken from the 1. and 2. pressure point place.
2. The kidnapper's buttocks are on the 1. and 2. pressure point place. It explains slight pushing on the fabric and the rounded imprints. Meanwhile, something was dragged from middle of the bed and then lifted from the biggest (3.) pressure point "knee".
3. Perp might've sat on the bed or messed with the bed after the taking of JB.
4. Contaminated crime scene; Touched, sat on, checked by unrelated-to-the-crime people.

Another explanation of the folds on the right side

Version 4. is pretty plausible, if somebody checked under the bed (imprints from palm on bed, while leaning to see under the bed, then helping with that palm/hand to stand up from crouched position, creating the strong "pull" lines on 3.)

Is this helpful? I am skeptical, because normally fabrics on crime scene are analyzed by experts, but perp has not been found yet.

I wonder if dirt or other nature elements were found by the bedside too.
