I feel much the same as you, but Thompson's behavior regarding the DNA is making me completely and totally doubt the veracity of the DNA, especially in regards to the chain of custody. There should be no reason not to share the chain of custody document and complete documentation of the processing of the DNA and how the IGG was done with the defense. In fact, of all the evidence in this case, this DNA evidence, because it is based on verifiable scientific processes done in labs, in a controlled environment, should be the evidence the prosecution is the least concerned about sharing with the defense - unless the prosecutor knows something is wrong with it. To me, it looks like Thompson is absolutely desperate to hide this DNA information from the defense and is having to be dragged kicking and screaming through the court process in order to surrender it to the defense. He even claimed the documentation of the IGG process doesn't exist in court and in front of a judge and then it has turned out that was not true. Which begs the question why??? Why is he behaving like this???
We don't have access to any of the reports or discovery, so we can only go on what is in the media so far.
We see Howard Blum wrote that they only found 20 skin cells or less when at least 80 are usually needed to get an STR. We also know some cells will be destroyed during the testing - 20% to 80% of the cells are destroyed.
"Currently, the optimum DNA input to the PCR for STR profiling is around 500 pg [[1], [2], [3]], which equates to approximately 80 diploid cells (∼6 pg/cell [4]). If the potential of DNA loss through workflow processing is not considered, any item from which 80 cells are collected should generate a full DNA profile. Due to inefficient collection of the DNA template present by swabbing or tapelifting techniques and the loss of DNA through standard extraction methods, reported to range between 20 %–80 % [5,6], far more than 80 diploid cells would need to be collected to ensure a full profile downstream given the optimum template stated [[1], [2], [3]]."
Even if the newest STR process was used that can be done on 5 cells, if the sample was 20 cells and then 80% of those cells were destroyed that leaves only 2 cells.
Was Blum right about the 20 cells or less? That begs the question, was the DNA STR profile from the Idaho crime lab partial? Is it possible that the Texas lab couldn't run the IGG because the sample was partial so the FBI lab took over? Could this be why the Texas lab's datafile is much smaller than that of the FBI? And even more concerning, is this why the prosecutor has been fighting against the defense seeing the DNA evidence?
We don't know the answers to any of the above questions, but they are reasonable to ask given that the prosecutor has been trying to do all he can to keep the DNA evidence and DNA evidence chain of custody from the defense.
All JMO, IMOO.
