Yes, you are correct about Allison being the one who was flipped over with her mouth open- and it was compared to the "7th body" photo that later turned out to be from a completely different crime scene- I saw that too and know exactly what you are talking about.
The photo of Dawn was lying on a morgue table as you also correctly described.
However- I believe you may be incorrect about Ronnie shooting Dawn from the doorway- he shot Allison from the doorway. Ronnie shot Dawn at close range (hence teh gunpowder on her clothing and severe damage to her face), and she had to have been facing away from him for the bullet to enter behind her left ear, causing her skull to implode.
Allison was awakened by the gunshots and looked up to see Ronnie aiming at her from her doorway- she was clearly awake as her eyes were open and her mouth open in a frozen scream of terror.
It breaks my heart, Allison would have grown up to be such a beautiful woman, I think she would have broken a lot of guy's hearts- all the kids would have had good lives ahead of them I think
Where's all the ballistics and forensic experts usually lurking around on here? My original question still hasn't been answered...
