Why I believe she was in that trunk for around five days or less - according to the forensics preliminary report when the LIBS test was performed, "as decomposition progresses various inorganic elements found in human tissue are found in INCREASING
CONCENTRATIONS in drainage from the decompositions events". [caps mine] That can only mean that as the decomposition occurs, these compounds such as iron, calcium, magnesium etc, begin to concentrate as they are emitted from the body. The LIBS test measures the different concentrations from the first day these elements are drained to the last day - each day will show a different concentration from light to heavier and heavier - he is not saying that he found A concentration of calcium and/or magnesium etc., he is saying he found DIFFERENT levels of concentration of these elements in the fluids drained from the body. That is that some of the fluid showed a lighter concentration while some of the fluid showed a heavier concentration.
I cannot think of another way to interpret the results from this test. It simply cannot mean that the body was placed there AFTER two and a quarter days, it means that the body was IN the car for 2.6 days. I keep trying to find an analogy and the only thing I can think of is a glass of lake water that has been sitting around - as you pour it out of the glass the sediment in it becomes more and more concentrated - the lighter part at the top is going to spread further than the heavier part at the bottom because the lighter it is the easier it will spread out on a surface. Why? Because the lighter part is less heavier than the bottom part. (Yes, I know, duh, but I can't think of another analogy that would illustrate the point.)
The reason this is important is because LE needs to narrow down a frame of time to place her in a certain area at the time the body was removed from the trunk. If as Padilla is claiming, the body was in the trunk for eleven days, then the concentrations of calcium/magnesium would have been much heavier than what was estimated. Secondly, what is apparently being overlooked is that the trunk liner is not the same as the trunk carpet - the liner is under the carpet - obviously, the reason the odour became more and more obnoxious is because the fluid leaked through the carpet onto the trunk liner. You could scrub that trunk carpet from now until kingdom come, but it would not take it out - it would be in the jute fiber backing and on the trunk liner and to get rid of it you would have to get rid of the carpet, scrub the trunk liner and use different carpeting. (And even then, I'm not sure that it would get rid of it entirely.)
So now, I believe that Texas Eqsh is going to go on a wild goose chase looking for "ping areas" near the airport, when in all likelihood the body is closer to home - probably in Jay Blanchard Park or Downy Park. (My hunch, since she was so eager to place herself in Jay Blanchard Park in that time frame and for another, she didn't look too worried on the night of the 20th which to me means she felt she might have solved a problem that day.)
