I think some of the confusion about DNA amounts comes from confusing the substances that carries the DNA with DNA. During the Caylee trials a scientist explained touch DNA and other sources of DNA. Per the scientist, touch DNA (skin sloughed off when you touch something) has to be replicated to produce enough of a chain to get a profile. There are DNA rules that apply to how much replication can be admitted into court.
DNA from bodily fluids produce plenty of DNA with long chains to get the profile of the person with no replication necessary. So, the DNA amount in fluids is way higher than in touch DNA. The reference to a pack of sugar was a reference to how much DNA was found when dealing with a microscopic organism. That was a lot of DNA chains as opposed to the partial DNA chain that would come from touch DNA.
I hate it when lawyers take advantage of people not being experts on a subject and try to fool them by lying by omission. Kind of like mechanics taking advantage of someone who is unfamiliar with the system on a vehicle.
Thanks for this post, I couldn't agree more.
The size of the DNA sample was normal, even more than it was needed to make a simple DNA profile from it. DNA is not visible to the naked eye. Of course it is just much much much smaller than a smallest grain in the pack of sugar. We can clearly still see the grain of sugar, can't we? This is absolutely a no brainer. I'm not being snarky, just genuinely surprised that some on a crime forum doesn't already know this. It was also clearly relayed by the experts that it was plenty enough and this wasn't rebutted by any defense expert. Why? Because this is a fact and is normal. DNA chain is always small. Otherwise let's throw out all the DNA evidence in all other trials in the history... This is not a pseudoscience.
It's like saying we can't get life threatening illness from a virus, bacteria of microbes because they are so extremely small that they are invisible to a naked eye, so the getting sick claim from it can't possibly be valid.
There is indeed a big difference between DNA and touch DNA. Touch DNA sample is even smaller than DNA and can be a result of a transfer deposit of skin cells. IIRC 7-8 cells are enough to produce touch DNA from. Touch DNA have to be replicated again and again to be able to produce a DNA profile from it as a result. With other words add even more zeros behind the 1: number representing the size of the regular size of a sample which can show DNA, and we will get the size of sample needed to get the touch DNA from.
This was a good enough size sample -even more than what is necessary to get a DNA profile from- as we heard the expert's testimony. This amount of DNA couldn't just be transference off of clothes or off whatever else. This amount of DNA could only be a result of CM physically being in his trunk at some point, one way or another.
Not to mention that according to EA's own statements to LE Christina was nowhere near of his car. According to EA his car was nowhere near to Christina's car either.
The cell ping evidence is also solid. The defense expert just conveniently "forgot" to add the portion of the data which is the most important part of it all. This was not an accident, this was an omission. I would go ahead and say it was lie by omission. He was talking about something completely different than what the state based his tracking on. This is how the defense again tried to muddy the water. It's understandable if people who are not really familiar with cellphone technology could be led into the woods with that testimony. But after that the prosecution on rebuttal recalled their expert, who clearly explained what the difference is and why the defense expert's testimony has nothing to do with what the state based their tracking on.
All IMHO
