No, this doesn't explain anything, you have assumed there would be 'drag marks' but that's not a given at all. Where did the blood on the pillow come from, it it wasn't from June being shot - I suspect you will say the police placed her on the bed after shooting her? So why move her from the position she was shot? No one would have known where she was shot and moving her causes problem for the CS.
Why are the blood stains on the wrong side of the bed?
Also, there is no evidence to show when the blanket was pulled to the floor, it doesn't have to have happened before June left the bed. Were the cartridge cases on top or under it? I can also see that there is some blood staining to it.
Which door was closed that should be open and which photograph are you using for this?
Yes because I have said and explained this before. They had to move her quickly to stop more of her blood staining the carpet.

https://jeremybamberforum.co.uk/index.php/topic,11579.msg533789.html#msg533789The priority after their initial shock and horror would be to minimise the blood stain so they put her on the bed while they considered what they would do. Unfortunately the bed was now contaminated with her blood and this led to the need for the story to include, that she was initially shot whilst in bed.
Thirdly moving a heavily blood soaked body would require protection from becoming covered in June’s blood. I have set out more on this aspect of their actions in other posts.
