Time and again through the last 10 threads, examples of people we can assume in equally poor condition as Jessica, as a result of fire have been documented speaking shortly after the incident. The inflammation, and edema caused by burns is not immediate. Here is where the introduction of flammable substances to the vocal cords and esophageal tract become important but not completely critical. People can speak without vocal chords, I can testify to that on the first hand. It is hard to hear or sometimes understand, and takes a great deal of effort, but it is possible. If her entire esophagus were obliterated you could assume the trachea suffered the same fate and she would have suffocated prior to emergency response arriving on the scene.
Re Eric/Derrick/Schmerrick etc... I've seen that quote "He said they told him there was an accident down the road and his name was mentioned" Now you could assume that Jessica gave that name, especially the way the story was reported, however, nowhere has anyone said "Jessica said something that sounded like Eric" Only the fact that his name was mentioned. Sha sha seemed a lot more talky before December 7, maybe she said something about Eric, maybe the talky FB people said something about Jerrick, maybe people at a party said something about Derrick. They only said the name was mentioned, and everyone inferred that Jessica was the source of that name. ( A lot of devil's advocating there. I do believe she said a name, and I believe they're working that avenue but don't have adequate evidence to convict) I don't know what name she spoke, but I believe she spoke a name.
I belong to the DTA club too, you want my trust you earn it, it doesn't come freely. A few details leaked and were left to twist in the wind. They've locked every detail of this case down for a reason, only people who were there / or spoke to those who were, are really going to know the details. When someone comes in with a story and can fill in the right blanks, they know they have the truth coming.
