I went to the Caylee Daily site and looked at the photos. I can see the outline since someone traced around the enhanced stain images. I would not have been able to make them out otherwise. However, being OBJECTIVE, I can also argue that there may be nothing to them. So if they are brought in at trial in some manner, I doubt it will do more than provoke thoughtful consideration of the visual of Caylee, deceased, decomposing in a trunk. Something was decomposing in that trunk, the evidence presented will identify that "something" as Caylee. The enhanced photo will just top it off. A chocolate sundae is still considered by most people to be a sundae even if the cherry on top is on the side or ommitted entirely. The positive identification of this stain as an outline of Caylee will only serve as topping and isn't necessary to make the prosecutions case. IMO
I doubt it would ever be brought in by the prosecution as evidence, but I do think it may have it's place during the penalty phase when they can use it to evoke emotion from the jurors. While Andrea Lyons will be attempting to "humaize" KC and evoke sympathy for her, the prosecution will be advocating for a little girl who seemingly has no supporters in her own family. I think this is where the real case will be made.
