I think that the odor/air sample evidence should come in even though it will be argued it is "new" or "junk" science This is why ...
It isn't new science. First of all, Baez asks the question of how can you measure an odor of something that is no longer there? That is classic JB at his best trying to confuse the facts. While it is true that the primary source (body) was removed, a secondary source of odor remained -- the saturated carpet. It's kind of like when you wash a pen with you clothes and the ink ends up on everything in the wash. The stains don't vanish just because you find and dispose of the pen. The measurement and identification of odors from collected air samples has been in practice for many years. I remembered an advertisement for a meter that you blow into and it will tell you if you have bad breath. It tested for the presence of bacteria and enzymes associated with halitosis.
Not NEW, Not Junk Mr. Baez! Breathalyzers work in a similar fashion. You blow into a machine (or so I understand) air samples are trapped in a sealed container then analyzed to give a qualitative measurement as well as a quantitative measurement in respect to concentration.
NOT NEW SCIENCE In this case the stained carpet was the subject and you can't ask a piece of carpet to "blow" so the carpet was allowed to off gas into a container and then an air samples were collected and analyzed. This is
NOT a new technique ...

Now onto the "not new" science of identifying specific odors using GC/MS.
"
The e-nose created by surgeon David Morgan and engineer Ritaban Dutta and colleagues can sit on a doctor's desk and analyse gasses given off by swabs from patients for signs of methicillin-resistant Staphylococcus aureus (MRSA) and other strains of Staph aureus." Replace "swab" with "carpet" and change the bacteria to those associated with human decomp. This method used to collect, analyze and identify sources of odor using air samples is virtually the same technique used by Dr. Vass. It has been researched and peer reviewed is accepted and again
NOT new!
I this isn't new or unproven science. I am sure that Dr. Vass is brilliant <3, but he did not invent the science, he merely expanded its application.
There are a ton of articles that discuss odor detection and identification. Below is my google search results.
