I will admit... I didn't try that hard to follow it Dr. Perlin's, I listened, but didn't even take that many notes because without the visual, it was pointless lol
This is what I learned today...
Christine Nash from Bode Technology...
They got some dna on 4 items to put it simply. It was degraded, I listened earlier today, but IIRC she said it was consistent with DNA that was exposed to the elements. When asked about them being contaminated with people processing the scene, she explained that if the evidence was stored properly, they would expect to see 'more' DNA, or more complete DNA profiles. (all paraphrasing, because honestly, I'm not listening to all of that again if I don't have to haha)
When the samples were sent to them, CODIS search was requested, but they (the defense) decided to forego that. Bode lab themselves do not have access to CODIS, but they can request it from another lab before they start processing the evidence, that other lab has to come and access the evidence or something first as well. It makes the process longer, no clue how much longer, but it delays the process. April 9, 2018 skip on the CODIS... her report was done June 18, 2018.
In regards to the above... I don't recall all the pre-trial stuff, when it was supposed to start, when delays came about, I could go back and look in the old threads, but does anyone know .. in April 2018, when did they think the trial was going to be?
Beatriz Pujols - Cybergenetics
She ran all the computer stuff lol There is way more to it, anyone that is interested can read it for themselves. Her work was reviewed by 2 other analysts, and then Dr. Perlin. Her report is dated January 11, 2019.
Dr. Mark Perlin - Cybergenetics
I mentioned it in an earlier post, but will mention it again, 90% of Cybergenetics work is with the prosecution, other 10% is defense, post conviction, family testing for paternity. The software TrueAllele is in crime labs, and of course, in that case it's 100% for the prosecution.
THE RESULTS:
I am not going to give the numbers, they were somewhat confusing, especially without the visuals.
They went through the exclusionary statistics for the following.
E15 - electrical cord ( I believe this is the one around neck/head based on the photo I have)
A3 - left bra cup - was in grave
E11 - white cord - was around Joey's waste area I believe
A25 - strap
When McGee asked him "does this mean he is excluded?" Perlin's answer was 'no, it means there is a statistical support to him being excluded'. (I believe this is wording they use with the probabilistic genotyping)
They were able to make DNA CODIS profiles for some of the evidence, which can be used to do a keyboard search in CODIS. If they were to get hits, they can then go back and check the probability like they did with the other known samples earlier with the McStay's/Merritt's DNA.
There was a
weak association between E09 (right bra cup) and E01 (white cord). E01 didn't have as much information as E09, that is why it's considered weak. This must the be the 'crossover' that was referred to in that article the other day. Those processing the scene... if one processed one and another processed the other... how did it get on both? I can't recall at the moment if Jones did all the swabbing of evidence himself or not, but he may be the only one that touched both, IF they are the same profile and IF it was contaminated during or after the discovery JMO
Cross exam of Dr. Perlin is not available yet.
