An often repeated false trope is that "it's impossible to completely clean DNA from the car". This is perhaps so much repeated because it is disproven by two endeavours that some more devout Probergers seem averse to - washing and science. This recaps the peer reviewed, published science and some real cases that prove it is easy to remove DNA and blood given much less time than Kohberger had.
We see anti-scientific nonsense such as "DNA is sticky", "it's impossible to wash off all DNA", "it's cellular so can't be removed". Passing over Proberger confusion of incelular with cellular, DNA is (as a rough, illustrative analogy) structurally similar to a cross between starch and protein - it has a starch-like backbone with the functional nucleotides (the G,A,T,C's which code for proteins) spaced along it, similar to amino acids on a protein - it is not "sticky" nor harder to wash away than most proteins or starches. If Probergers think it impossible to wash away or degrade starch I'd strongly recommend not eating in their kitchens.
The peer reviewed, published science shows it is easy to wash away all DNA and blood, beyond forensic profiling or detection (studies linked for each point):
- Washing with water aloneĀ is sufficient to fully remove DNA from many surfaces
- Washing once with simple dish soapĀ is sufficient to remove all DNA from knives
- Washing carpet with hydrogen peroxide >3%Ā destroys all DNA. (Peroxide is commonly sold at c.10%)
- Household cleaners with "active oxygen" (peroxide source)Ā destroy blood and DNA and prevent blood reacting with forensic visualisation reagents
- Peroxide is the bleach source inĀ "color safe" laundry and fabric cleanersĀ that do not leave bleach marks
- Hydrogen peroxide decomposes to just oxygen and water - forensically undetectable
- DNA removal products, used in biomedical labs where eliminating all traces of contaminant DNA is critical, are even sold on Amazon as sprays, even as wet wipes - these degrade DNA in a few minutes, but are based on common household cleaning agents
Many murder cases involve scenes where people were stabbed to death being cleaned of all blood/ DNA in a very short time, often only a few hours.Ā A few of many such examples:
Robert WoneĀ - fatally stabbed, lost 2/3 of his blood volume in the house. Scene was sealed within 50 minutes but no blood or DNA was found other than a spot on the bed police thought was staged. 3 male residents of house appeared freshly showered when police arrived, and were suspected of washing/ staging the scene.
Samantha KoenigĀ - murdered by serial killer Israel Keyes; sexually assaulted and murdered in his garden shed. Her body was kept in the shed for 2 weeks, mutilated, dismembered and then transported. Keyes boasted the FBI would not find any DNA - no DNA or blood was found in his shed or the car used to move her body.
Claudia Maupin and Oliver NorthupĀ - stabbed, mutilated, disembowelled and dismembered by a 15 year old school-boy, Daniel Marsh. Marsh left none of his DNA at the scene or on the bodies (despite sexually motivated assault, organ removal and insertion of objects into chest cavities) and cleaned away all traces of victim blood and DNA on him, tracking zero DNA to his home.
Given 7 weeks to repeat wash a car where no one was actually stabbed (and where the starting amount of victim blood/ DNA may have been limited by simple measures as removing an outer hoodie and gloves) surely Kohberger could clean as effectively as a 15 year old school-boy? It seems that, for some, ignoring science and real case examples is the only rinse and repeat they entertain with regard to the car cleaning.
Ā all know they spent hours cleaning with just regular soap and water
Who are "they"? We do know there was enough evidence to support arrest and indictment of Kohberger at three judicial/ quasi judicial processes - approval of arrest warrant, indictment and maintenance of the indictment. Could you perhaps share some, any or even an iota of the evidence that supports your "group of people" theory?
Why did they leave the diamond pattern of the latent shoe print in blood in the hours of cleaning- must have been very inept cleaning? And how did the "group" avoid leaving multiple shoe prints - is this a murder by maniacs mounted on pogo sticks or stilts? Perhaps a vicious group of travelling circus acrobats have struck, yet again?
said the car would be a rolling crime scene??
Donning an extra smug hat, myself and u/rivershimmer did predict the car would have no victim DNA, on a post a while before that was known ( it was a "what are your bold predictions" type post). It seems for some the presence of DNA (sheath) is not significant, while the presence of DNA on a glove is, and the absence of DNA in a place it unsurprisingly is not is very significant.
a similar absence of dna material that could had been cleaned if there was no such material at the scene of the crime itself
The perpetrator was fully clothed, with gloves and a mask. There is very little scope for his DNA to be left at the scene - spit and snot precluded by mask, most by gloves, probably cap or ski-mask precludes hair. Victims grasping with nails likely just raked his outer clothing. Many stabbing cases would not involve transfer of the knife wielder's DNA to a victim, even without gloves/ mask.
The case I linked of Claudia Maupin and Oliver NorthupĀ illustrates this - the 15 year old perpetrator used mask, gloves, full coverage of clothing, even used tape on his shoes to obscure his shoe prints. He left zero DNA at the scene despite mutilating the victims and inserting objects into chest cavities from which he had removed organs.
whether they can trace any orders from places like Amazon for these type of chemicals
Hydrogen Peroxide is sold in every pharmacy and most supermarkets. Similarly cleaning products with "active oxygen" are sold in every supermarket - he didn't need any specialist chemicals. I put some in the post just to illustrate, e.g. with the DNA Away Wet Wipes, how easy it can be to remove DNA from a surface - alot of those specialist products are just based on detergents and reagents you'd find in household cleaners like peroxide, hydroxide etc i do wonder what he bought at Albertsons later that morning. Agree, lining the trunk and placing items there before driving off would be good way to limit contamination of car.
DNA is water soluable
Yes indeed - not the incredibly "sticky" substance some claim. Some extraction techniques for subsequent manipulation rely on differentially reducing its water solubility. ETA - i like your username, on the subject of reducing affinity for water!
Iām not going to take your word for the āno physical changeā to fabrics.
Hundreds of laundry, car upholstery and fabric cleaning products use peroxide - including the best selling brands in the USA and Europe. If they damaged fabrics it would be noticed. They would all not have "fabric safe" on the packs and adverts, which they do
Here is one study which used hot peroxide vapour, much more agressive than 3% peroxide liquid - and showed no effect on fabrics under even a scanning electron microscope. Only wool showed any change - and wool generally can't be home laundered. Products sold for use on fabrics are tested to ensure no damage to the fabrics.
Peroxide at 3% can be used to wash skin wounds and to gargle with - so not so aggressive as to oxidatively damage tough nylon or polyurethane car seat fabric or carpet. Why, if you can gargle with it, do you think it would degrade, destroy or oxidise car carpet fabric?
For these reasons your point seems misguided. Also pretty irrelevant - repeat washing of fabrics does lead to change through friction, clothes do wear out. Fraying or loss of tensile strength of fabrics might be present from general wear. I note you didn't respond when I provided detail and peer reviewed papers to address your point that active oxygen cleaners would not degrade blood. I have even attached a picture of a car upholstery cleaner with active oxygen above.
and where is there reference to microscopic examination in any of the references you provided
This study looked at effect of hydrogen peroxide treatment (as a vapour, much more aggressive than 3% gargle/ skin wash strength - peroxide vapour treatment was developed as a sterilising treatment for anthrax attacks) on textiles common for upholstery - such as nylon, polyester, leather, including Nomex which is a polyurethane fabric (similar to nylon) used in car seats and carpet. No change under scanning electron microscope examination....
shoes matching the foot print in the house is just ridiculous
So the shoe print size matching the shoe size of the man whose DNA is in the house, who matches the eyewitness description and whose car was also outside....is ridiculous.... but...
the killer had asked him to pick him up from that address at 3:30
...... is more credible? I see
I note the killer was 50 minutes late, keeping Kohberger waiting from 3.30am until 4.20am. Killers nowadays are so rude, selfish and annoying! How unfortunate Kohberger turned off his phone, as you do when you go to pick someone up and they don't show for 45 minutes....
BKās it very well could have been because the killer had asked him to pick him up
Why did he file two sets of alibi perjuries then? His alibi states your zany story is untrue. So now you allege BK is also lying. What a tangled web!!
bears love coins so itās always best to put them in Ziplock bags,
Very true. Many bears have serious gambling addictions to coin slot machines and lottery scratch cards. They struggle to open the zip aperture on ziplock bags due to their large paws.
innocent person ends up in the same position in terms of the absence of evidence.
Yes, which also tends to increase the contrast between an innocent person and a person whose: - DNA was found under a victim's body - car is on video at 22 places all consistent in time, location and direction with travel between his abode and the scene - height and build match the eyewitness description - statistically unusual size 13 shoe prints will match the prints in blood at the scene (my speculative prediction) - "alibi" confirms the state's narrative about his whereabouts, and his car, at 4.00am that morning
That DNA can easily be cleaned away over 7 weeks is not surprising nor particularly useful to the prosecution, I agree. But nor does DNA being easily cleaned from surfaces dent the state's narrative. Eta - size of shoe prints
We arenāt talking DNA here
No, we are talking mainly DNA. If the DNA is degraded, blood even if visible, would have little evidentiary value.
But you perhaps missed the point, and the linked study, in the post above which specifically addresses removal of blood - peroxide based cleaners destroy blood, including rendering it non-reactive with forensic visualisation reagents like luminol. Peroxide degrades to just oxygen and water. These "active oxygen" products are the color safe fabric cleaners which do not leave bleach marks. Here is the study, linked, again:
mean are we supposed to believe he did this without anyone noticing
Did he not like to go for night drives, frequently, in remote areas? Are there not many rural, isolated spots where a car could be cleaned?
for there to be no record of him buying the stuff
Maybe there are records he bought cleaning products. He is on video in a supermarket a few hours after the murders, but at the time PCA was drafted no info on his purchases was available. Peroxide is cheap and sold in every pharmacy and most supermarkets - he could have used cash.
remnants of cleaning materials in his apartment
As he would have disposed of clothing worn that night and the knife, he may also have binned a few empty bottles of peroxide. Is your argument really that he could not dispose of some cleaning product containers?
had been cleaned it would be obvious because there would be very little of BKās DNA in there either
This is utter nonsense. There is no quantification of DNA on surfaces in such testing - either there would be a recoverable profile on surfaces like steering wheel or not. DNA is taken from a swab. There is no quantification of a "week's worth", or three week's worth of DNA. Even if a total surface area was swabbed, it would be impossible to tell from DNA results when the surface was last cleaned - there is a dynanimic equilibrium between degradation of DNA on a surface like a steering wheel, particularly in daylight and with humidity/ warmth, and further deposition of fresh DNA.
And I donāt care what Repulsive says
I have used peer reviewed, published scientific studies which are linked in the post which show exactly that blood, aged/ dry blood, is removed and degraded, as is DNA by active oxygen, peroxide cleaning products. I also linked studies showing these do not damage fabrics, including under inspection by scanning electron microscopy. I also linked many products with active oxygen which have "fabic safe" on the pack.
It is not what I say, but what the science has established.
structure of that material that will be observable, if not to the naked eye, then definitely microscopically
Here, again, a study which looked at effect of peroxide on fibres, including nylon and polyurethane as used in car interiors showing no change.
will physically alter the fabric they have been used on, perhaps not to the naked eye, but definitely to the microscopic appearance of the fabric.
No - many laundry products use peroxide and peroxide sources and are specifically tested to ensure they don't physically change or damage fibres, including microscopic inspection. Laundry products have had peroxide sources since the 1970s and especially since the "Persil Power" debacle where a new cleaning reagent did indeed damage fibres, these products are tested to check for damage to fibres. Some friction, wear of car seat or floor fabrics etc could not of course be attributed to aggressive washing versus years of rubbing with various clothing fibres or shoes of course.
If they are used on any kind of fabric they will oxidise that as well and the effects
Again, peroxide is very commonly used in fabric cleaners, stain removers and laundry detergents - it does not cause bleach marks or fabric damage. These products even have "color safe" or "fabric safe" emblazoned on the packs. Tide with Bleach is one of the biggest selling brands in the USA for clothes washing - it utilises active oxygen as bleach source. Active oxygen products are also sold specifically for use on car upholstery.
Eta - some example products - that don't leave bleach marks, are color safe, fabric safe etc
But what about dried blood? Because that is what forensics were looking for in his car
The linked studies, in the post above specifically address removal of aged, dried blood, including up to 40 days old dry blood on fabrics - peroxide based cleaners destroyed dry aged blood, including rendering it non-reactive with forensic visualisation reagents like luminol. Links to study and excerpts on dry, aged blood below.
From the linked study: "the experiment they carried out involved placing blood onto white cotton, a pair of jeans and a towel and letting these dry for different lengths of time, namely one, five, ten, twenty, thirty and forty days respectively. The samples were then taken and washed using a product containing active oxygen. Regardless of the type of material used and the time that had elapsed, in every single case where the three tests were performed, the presence of blood was not detected"
would show in photos of an impeccably clean car
He may have cleaned it 10 times before the 2000 mile interstate journey back to PA from Dec 13th? A very tidy looking, clean car is also not very definitive though in terms of a scientific indication about DNA recovery. I agree though, also if he was pictured or filmed cleaning the car while under surveillance in PA, might be another point for jury to consider but not strong proof of anything.
of the shoe print has NOT yet been matched
Are you having reading issues. I wrote "likely fit" or "if fits"
Your new theory is Kohberger went to pick up a killer at 3.30am, drove around for 50 minutes waiting, but kept his phone off. You should write bizarro TV comedy scripts.
aviation textiles. Not cheap Elantra car textiles. A
The study used nylon, polyurethane fibres, polyester, leather, and Nomex. Nomex is a nylon type fabric used in cars specifically. But nylon is nylon, polyester is polyester, whether in a plane carpet or a car.
The "however" relates to wool, which does show change after 10 treatments - expected as wool can't be washed at home with normal, non bleach, detergent - it is also not used in car seats....
The study used 10 treatments with peroxide vapour, much more stressed than 3% peroxide that can be gargled with. Peroxide vapour treatment was developed as a sterilising treatment for anthrax attacks. The study I linked in the post shows 1 treatment with > 3% peroxide in water solution is sufficient to degrade all DNA in carpets
how does parking close to the house definitely place him in the house?
The video of his car circling the house 4 times and speeding away from the scene just after the murders is given more context by his DNA on a sheath under a body in the house. Similarly the fit with eyewitness description gives more context, And likely the fit of his statistically unusual size 13 shoes to the bloody shoe prints inside the house.
there was no evidence any cleaning solutions
She did not mention cleaning. She said something like "no explanation" for lack of evidence in car. A bit meaningless as a lab report of a negative DNA test would not speculate on why there was a negative. And as I note in the post very effective DNA degrading agents, like peroxide, leave no chemically detectable residue at all - peroxide decomposes to just oxygen and water but even used quite highly diluted at c 3% one wash would destroy all DNA on fabrics.
which you realistically can't given cash purchases/
I agree purchases likely cash and harder to trace - however the Albertsons purchases right after the murders were probably obtained given he is on CCTV, the till receipt sale info could probably be obtained as the exact time and checkout for transaction known. Speculative, but phone GPS may give similar info for other store visits - his phone was on for the Albertsons shopping.
Re car DNA, the absence of his father's DNA in the car would, if the case, also illustrate cleaning to the jury, given he had sat in it for c 70 odd hours. That profile was already available for comparison.
the parking lot at the Steptoe apartments
Why would he clean his car there and not in some more out of the way place?
Ā car with water in the middle of winter
Do people not clean their car interiors over winter? Do people never spill anything in winter? Do valet and car wash places close over these months?
smell the bleach he was using
Hydrogen peroxide, as well as decomposing to just water and oxygen leaving no trace, is also odourless. But he would probably have cleaned his car somnewhere there were not people walking right past it....
Now let's play roulette.
Maybe less dramatic. Perhaps a prosecutor just asking a biomedical or forensic scientist -"can DNA be quite easily cleaned from a car given 7 weeks" might suffice. Evidence of Kohberger repeat cleaning the car (e.g. from PA surveillance or perhaps from his phone GPS history) would be, to me, a fairly weak piece of correlation, but may still have limited significance for jury, especially if quite unusual in frequency or duration of cleaning, or when such activity started. Similarly, purchase receipts for large amounts of cleaning products starting on and repeated after Nov 13 might also be a limited but not insignificant correlation, if no such pattern existed before Nov 13.
there still would have been a weeks worth of his degraded DNA. They canāt get a profile from it
How would they know it was "his" DNA if it was too degraded to profile?
And, given DNA on a surface is constantly degrading, what is a "week's worth" of DNA. That cannot be known - a sneeze or glob of spit, from an Exaar rap lyric shouted with excitement perhaps, might suddenly deposit three weeks "worth" of DNA.
never struck me as a female and appears to have infinite time
Yes, I just accepted after someone, maybe themselves, claimed they were female. But on reflection, and with knowledge of the Game of Thrones weird fixations etc, and what seems to be maybe hundreds of accounts, it does seem more like a weird man (not being sexist, but that type of sock puppetry and passive aggression using alt accounts seems more typical of tragic over-online male behaviour)
I have a new accuser, lol - apparently now I am some sort of secret operative out to nobble the trial through the medium of Reddit posts, it is very exciting:
I'm not sure about the flu references. Pineapple seems extra fruity. Someone else told me the GAC is a podcast and Streak is the host, I am thinking something similar to the Crime-clown, Baffling but intriguing that Chief Fry went transatlantic for his conspirator to leak publicly available, Google searchable documents though. The Pineapple is tracking the leak back to me however. Coded messages about this matter only form now on, pineapple is not the only hairy fruit. The penguin flies by night...over and out.
šš¤£š It does have an ideal rolling "r" sound leading into a more echoey "bees" consonant sound
NO EVIDENCE OF CLEANING.
First, that was not stated - she said "no explanation", which is fairly meaningless, as a report would likely just note no DNA, not speculate why.
Second - as I note in the post and perhaps you missed, reagents like peroxide decompose to oxygen and water and are totally undetectable.
Third, a trace of detergent would be meaningless as it would just indicate the car, which had several previous owners, had been cleaned at some previous point.
Georgette "Tenders" Thibodaux, purple Fabuloso destroys all DNA evidence in seconds
Tenders is, as usual, absolutey correct. However, care and restraint should be used before attempting to use Easy-Off Bam or any Purple Blaster for more intimate hygiene needs. I am still haunted by your woeful tale of "Flea-Dip" Perkin's inflamed nethers after her foolhardy and ill advised choice of Oxy-Action for her downstairs cleaning regime.
The day of, LE said the bathroom was so most disturbing room in the houseā¦
Well, to start, that was never said. Can you link any credible source or report, please?
There were however reports which claimed as the source PA police officers surveilling stating Kohberger was observed cleaning the car.
How come we never saw pictures of blood in the top bedrooms
No pictures of inside any room was ever released. Inside shots of lounge and kitchen and KG room were taken from outside. MM's room was never seen until FBI did 3d scanning after the house had been cleaned.
got him in trouble in high school. ("just masturbating"
Goodness! This may explain the typos and frequent descents int0 n0nsensical gibberish - one handed typing.
it might not be a male behind these accounts.
Yes, for a while I though it might be a rabid gibbon, a highly trained hamster with a keyboard pointer or some form of defective AI wired with only the memory chip from a domestic toaster.
was a juror, I would not buy that. Thatās too much of a coincidence.
Yes, good point, especially in context of sheath DNA, car video, eyewitness, shoe print...... it might look worse if PA police who surveilled him testify or have video of repeat cleans of the car, or unusual, very lengthy cleaning. I suppose it is another piece of correlation, albeit not powerful on its own. I actually think the shoe print, if it matches his size 13, would be another quite convincing correlation in overall context. Car cleaning harder to refute unless BK testified to why he was cleaning.
Very good points. On the "defund" seems unlikely - he wanted to be in police (attended protective services course as oart if ambition to be in police, before being removed from course for an incident with female students) and applied for the Pullman police internship.
looks like itās been detail cleaned it probably means he was trying to hide something
I do see your point - it is possibly an inference a jury might draw, but not a point the prosecution could place alot of weight on as there are too many easy excuses for repeat cleaning a car. He could just say he spilled a vegan soy milkshake or some Thai food in the car in November and had to scrub it out?
Kinda rude. The absence of those things means he cleaned
Sorry if was overly direct! It can't be concluded with any scientific reliability that absence of pollen, dust etc indicated that he cleaned or what he cleaned with. If he cleaned the car 15 times in November before driving 2000 miles from Dec 13th there may still be dust and accumulation of pollen or other material from the drive back to PA - doesn't mean he didn't clean before. Similarly he may have vacuumed after he got home. Similarly, a trace of detergent could mean the car, which is third hand iirc, was cleaned at some point in last years. Even if he was filmed cleaning the car when under surveillance in PA it would be a fairly weak correlation as could be explained by various excuses/ habit etc.
cleaning product would eliminate dust, dander, pollen
This is very nonsensical and meaningless. The absence of pollen or skin doesn't indicate anything reliably or with scientific certainty about cleaning to degrade DNA.
is the lab going to be able to determine if it cleaned 6 weeks ago or 7 weeks
I don't think you can date a rug cleaning. If you used peroxide, no trace. If you used carpet shampoo, any residue would be pretty impossible to date. Surfactants are mostly just long chain fatty acids with a more polar group at one end - not much in terms of any degradation products to date, and also nearly impossible to establish any rate for limited oxidation or hydrolysis products.
Ps - i hope its a red, or very coloured, rug.
Brushy-Berger took over from Bushy-Berger. The Wash'n'GoBergers believe that Murphy was rinsed clean of the crime, but the Elantra was not.
Thanks for a reasoned comment. Responding on a few points:
On large quantity of DNA, a few factors may mitigate. (1) He had 7 weeks to repeat clean (2) Quite easy to have limited contamination into car by taking off outer clothes, or simply using a stretch car seat cover. Ignoring speculation about seran wrapping car, there are cheap waterproof seat covers used by tradesmen and hunter, under 20$ that can be fitted and removed in a few seconds. (3) Along lines of repeat cleaning, but very easy to use an excess of peroxide or similar
The cases I cited were iirc c 2014. I don't think forensic blood visualisation reagents have changed since (luminol, phenolphthalein). DNA testing has improved in terms of "completeness" or individual specificity of profile, not in recovery of DNA to be profiled which is done via swabbing or removing parts of surfaces. Again, if DNA was degraded by peroxide, as the studies I linked show after 1 treatment, there is effectively nothing to recover even using better recovery techniques.
significant amount of blood on his clothes and shoes (e.g., the latent footprint)
The latent footprint suggests the killer had little blood on him - that footprint was not visible and required a forensic visualisation and a protein stain to be seen. That suggests most blood had worn off his shoes - that and the complete absence of footprints or even drops of blood outside the house suggest he wasn't drenched or dripping blood.
you have not shown me results of a test done on Elantra car interiors a
šššš¤£š¤£
To recap your free-wheeling, science and logic denying nonsense:
you said the post addressed only DNA, not blood and that blood would not be removed by peroxide based cleaners. I linked the studies which show blood is removed and associated DNA degraded by such cleaners. You ignored this.
you then said that old, dried blood would not be removed. I linked studies showing old, dried blood up to 40 days was shown to be removed. You ignored this.
you then said cleaning products would leave chemical traces. I linked studies showing peroxide decomposes to just oxygen and water, forensically undetectable. You ignored this.
you then said peroxide cleaners would oxidise fabrics such that use would be obvious. I linked many products with peroxide which are labelled "fabric safe". You ignored this.
you insisted that peroxide would show effect on fabrics. I linked a study showing no effect on fabrics. You ignored this.
you then said peroxide would show effects on fabrics if viewed under microscope. I linked a study showing that even examined under a scanning electron microscope after treatment 10 times with much harsher form of peroxide than a fabric cleaning product there was no effect on fabric types used in cars. You ignored this.
Sadly, as you seem to not engage in any good faith discussion, and have a style very, very similar to an other username who also "discusses" and ponders science much like a brick wall, your replies will be treated as comedy. Speaking of which:
You then state that the likelihood of Kohberger's shoe size matching the shoe print is "ridiculous" while putting forward a rather zany theory Kohberger was waiting for a killer who was 50 minutes late but kept his phone off. You ignore this contradicts Kohberger's own two "alibi" statements so if true he has already filed two sets of alibis, i think under perjury, which are lies. Most odd.
This is airplane fabric, not Elantra car fabric
Nope - this is nylon, polyester, leather, Nomex etc - fabrics which can be used in planes ( seats, carpets) but also anywhere else.
Nomex is used in car upholstery.
I already told you what is after whatever - discussion of wool after 10 treatments with peroxide gas, not used in cars.... which i mentioned in the first reply.
Our Man in Havanaā reference in the recent Curb Your Enthusiasm
It was a perfect call. I love Curb. I don't think I will be able to hear the sound of flip-flops in a resort without an unpleasant mental image however.
donāt think there would be any degraded DNA present in a car
Not what I wrote. I said the notion of quantifying a "week's worth" or any other quantity/ time comparator of DNA in a car interior is complete and utter nonsense.
he has paid cash for all this stuff that LE has been unable to locate any signs of.
- What stuff?
- If he paid cash a receipt would be easy to dispose of, and harder to track purchases
- A car seat cover and a hoodie or overall would be very easy to dispose of in 7 weeks
- Someone disposing of a seat cover or hoodie is not as incredible as the FBI assassinating someone to cover up a mass murder as you have postulated. Surely under any of your FBI/ Kopacka scenarios the FBI would help dispose of murder materials? šš
there are receipts for them, just like the Dickies receipt t
Dickies make car seat covers.
But I think a small paper receipt might be disposed of with 8 weeks to do so?
Not all the DNA in a car interior would be expected to have been degraded by UV
UV, moisture in air warmth, time...
Bacterial "degradation" would render DNA unprofilable.
The point remains irrelevant as no meaningful quantification, in terms of how much DNA us expected iver tine in a car interiirk, or comparison of quanities, is remotely possible
was no evidence of any DNA on the interior of the car that would indicate evidence of recent cleaning
No evidence of victim DNA may indicate the car was cleaned 6-7 weeks previously.
There may have been very limited contamination of the car. While people chunter about saran wrapping the car to make it look unreasonable, there are cheap water-proof stretch over car seat covers used by hunters, builders etc these cost c $20 and can be fitted/ removed in a few seconda; such a cover and taking off outer clothing like a hoodie or jacket would limit possible contamination.
Have you ever seen or read an actual electropherogram?
Yes indeed, very, very many...
that degraded DNA DOES show up on them.
Depends on the type of degradation. DNA exposed to UV light will undergo fusion of the two stands - that type of damaged DNA can't be processed by PCR.
Your point is still irrelevant - there is no such thing as a "week's worth" of DNA in a car, degradation rates and deposition rates would be far too variable and idiosyncratic for that to be remotely possible to establish or infer anything from in this case.
She mentioned something about cleaning
Am pretty sure it was "no explanation for lack of DNA"
A lab report showing negative result would not have speculative commentary, in same way a toxicology report would not speculate on negative results (or the source of a toxin in a positive result vs what sample it was found in)
šš¤£š or do the coins reflect a surprising number of trips to a coin operated car vacuum and jet-wash? The coins were in a ziplock bag (BigZ strike again) which struck me as very tidy, but alas clearly I fail to see that as his car had some stuff in it after a 2000 mile drive it could never, ever have been cleaned.

He had 7 weeks to repeat clean. And he may well have cleaned as if his life depended on it - as it did.
Fabric is easily cleaned with liquids like peroxide or an active-oxygen fabric cleaner. Peroxide can easily be poured or sprayed on any crack or crevice. If he had some blood spatter on his clothes, it did not volatalise into an aerosol and get into air ducts - it would have transferred via direct contact onto surfaces that can be cleaned. No one was stabbed or bled out in his car - his spattered clothes may have contacted the surfaces.
We do know he was not drenched, dripping blood - there was zero blood, not even droplets, outside the house. The latent shoe print outside DM's door shows blood on his shoe had already largely worn off to just a trace as he crossed the lounge toward the back door.
