Dr. Furton (the expert who does have a background in chemistry), a very well respected chemist in the field used a lot by FBI, DOD, NSF, etc, stated that the decomposition signature in the air sample from the Pontiac trunk was consistent with the decomposition of fatty acids present in the trash items that were in the trunk (i.e. bag of trash from the trunk, and maybe other items. Remember there was the crystal light container in that bag that the FBI lab said appeared to have urine in it, Wasn't that the bottle found at the remains site? There was a bottle/can in the trash that contained chewing tobacco but no urine etc, hair in that bag, various food package items, the used pizza box, stained napkins, etc, all sitting in the heat of the trunk at the towyard.) The prosecution apparently had reports from two of the chemists in Dr. Vass's group, as well as from Dr. Vass, but chose not to use the reports by the chemists, and only used Dr. Vaiss's testimony (he is apparently not a chemist). While his major was not in chemistry he still was required to take chemistry and has an understanding of chemical compositions It sounds like the defense will argue this point. It looked from evidence testimony like the defense will also argue the fact that Dr. Vass only included chloroform in his final report after receiving info from the investigators/prosecution that chloroform was suspected. And, one of the control samples (carpet from car trunks not involved in this case) supposedly also contained chloforom in its air signature, so that most likely will be a point mentioned at trial. The control sample contained very little (normal) amounts while the carpet sample from the Pontiac contained amounts that were over the capability of the meter to read it, something like 10,000 times as much as normal. Pure chloroform I believe they said.
The thing about the trunk smell that still puzzles me is that Casey was talking openly to Amy saying there was a smell in her car, wondering what it was, finally saying it must be from an animal. The prosecution insist decomp in the trunk must have begun around June 16, and that Casey finally abandoned the car due to the smell. Yet, Tony L stated there was no smell while standing next to her car on June 23 and I believe he stated that all he could smell was the gas. (? please correct me on that date), and Tony and the roommates said she parked the car at their place up to the day at Amscot and apparently they didn't notice any smell throughout that time, they stated no strange smell on her person either while she was driving it. Tony stated in his depo that they pretty much used his car when they went out. And there was one day when KC went to Jesse's to shower. [/INDENT][/COLOR]
I agree it's strange that this bag of trash would be in her car trunk to begin with, that's the main question regarding the bag of trash that still puzzles me. That, and whose urine was that in the container LOL
