I am with you when you say that this is one instance that you wish you were wrong. I am one of those people that sincerely likes to be proven wrong-I love a good discussion, and I enjoy being educated by others while taking in new information, new perspectives, etc. Unfortunately, the mishandling of this particular crime scene is nothing that we can wish away.
I am keeping my fingers crossed that Jessica's body preserved some type of evidence-beacuse the entire scene of the fire as well as her car can pretty much be written off as a bust, IMO. What wasn't ruined by LE and first responders was tainted by the complete lack of protocol. However the increased tip $ from the FBI did put a damper in my vibe as far as hoping for evidence to have came from her body. While trying my very hardest not to be pessimistic, I am currently of the opinion that aside from either a direct confession from a perp or somebody snitching with VERY persuasive information-along with some type of evidence-be it shoes/clothing from the night of the murder, the container of accelerant used, a video, or some other sort of physical evidence tying said persons directly to the crime; this is going to be an extremely difficult case to prosecute. This is clearly JMO, and it is subject to change in the morning, and I sincerely hope that what my gut is telling me, is wrong.
