A gas chromatograph. Samples from C. Anthony's trunk were analyzed using a similar device
For the first time ever, air analysis may be used as evidence in a trial. Not just a trial. Her trial.
No, this isn’t out of Fringe or CSI. This is a newer methodology, something that has never before been used in the courtrooms. Scientists from Oak Ridge National Laboratory took samples of carpeting from the trunk of Ms. Anthony’s Sunfire, and they ran a series of analysis on it. They also included samples from two other Sunfires, a pizza box, and a blanket that had been wrapped around a dead child who had decomposed in it for months.
First off they found chloroform. But after concentrating the sample, they were able to detect 51 chemicals, 7 of which are linked to human body decay.
This isn’t junk science. The methodologies behind this had been proposed earlier to discovered unmarked grave sites. Unfortunately, it isn’t mainstream yet, so it may or may not be allowed in the courtroom. It also isn’t a proof positive, since in the report from the analysis, they admit that the data is not 100% conclusive. However, it does lend credence to the state’s argument. Or maybe I should say the more likely side of the truth.
The idea itself is pretty cool. To those who say it is baseless science, remember that dogs do the same thing, without expensive laboratory equipment. They follow their noses, which are far more equipped than ours for picking up scents. However, it is a new science, and one thing given in science is that measurement comes with uncertainty. In my engineering program, we’re required to take courses on measurement, and courses on engineering statistics. As scientists, you have to be able to qualify your data, and provide confidence levels. “Oh, it’s pretty close,” doesn’t cut it. ’99.5% chance that this is exact,” that’s what we’re talking about.
Should the judge allow it as evidence? Personally, yea. It is evidence that is workable from both sides. Also, they still allow fingerprinting and ballastics work as evidence. You would be amazed to learn that these two types of evidence, central to so many cases, are not yet fully backed by science. More work has to be done to determine odds of a match. It’s more police work than science, which is dangerous. “Yes, it is a perfect match, this is the only person/gun it could match to,” is an opinion, sad to say. Not a fact. So if they are going to accept that, then “air science,” might as well to.

All Caylee wanted was love. All Casey wanted was to sex and party.
Either way, we’ll see what happens. This is turning more and more into an all-star event, from high-dollar attorneys to cutting edge, national laboratory science. Unfortunately it still circles around poor Caylee. Hopefully her soul will soon be at rest, with justice served to her murderer.
