Jury back.
Continued direct of Dr Vass by JA.
The chart he was shown (marked as next Exhibit) is the graph showing the inorganic compounds found on the LIBS from the junkyard car sample. Calcium was essentially not even present. The tall peaks were from the ICA car - calcium one of the main inorganic compounds in decomp.
He also tested the carpet using very minor chemical extracts. He did them. They cut a few of the fibers and placed it in methynol overnight and then injected it into the GCMS. This was to detect compounds that weren't going into gas form. The headspace test only shows elements coming off of carpet, not stuck in it. They found the presence of beuteric acid - a volotile fatty acid found in decomp. It is the first compound liberated during decomp of the volotile fatty acids. This was actually in the carpet itself.
His first reaction to opening the can - he jumped back a foot or two. It was very, very strong and he immediately recognized it as human decomposition that he has smelled for 20 years.
