Why was none of Kohberger's DNA recovered from the trash in Pennsylvania and is that itself circumstantially incriminating? Was the trash DNA another stupid mistake showing the glaring gaps between Kohberger's theoretical knowledge of investigations vs practical police work?

Kohberger had been in the PA house for over 2 weeks, and a full week between trash collections, when police lifted the trash. Browsing Reddit this morning it occured that I'd already binned, in just 1 hour, alot of items with my DNA - dental floss, interdental pick, cotton buds, surface wipes, paper napkin, drink can, kitchen paper used to dry hands etc etc

Is seems wildly improbable that in an accumulated week of trash there was nothing with Kohberger's DNA -- unless he was taking extraordinary measures to separate his items and dumping these elsewhere.

Kohberger was wearing medical gloves separating his trash into Ziplock bags when police raided the house in the early hours - per a named, credible source: the deputy DA, Monroe County Prosecutor Michael Mancuso.

Kohberger was reported to be dumping trash away from the home, at 4.00am, and was also seen wearing medical gloves outside on several days preceding his arrest:

Inside surface of medical gloves would be good for DNA collection, so it seems irrefutable that:

• Kohberger was separating out all trash items that might have his DNA
• Kohberger was disposing of these items away from the family home, into neighbour's trash but maybe further afield also such as bins in restrooms or other public areas

Leaving aside speculation about the efficacy of Ziplock bags to deter bothersome, bucolic bin bears and ravenous racoons rummaging in rubbish for vegan nibbles, as irrelevant to Kohberger ditching trash well away from the home, to question:

Is the total absence of Junior Kohberger's DNA in a week's worth of trash suspicious and, to some extent, circumstantially incriminating?

Does this 4.00am medical glove wearing, Ziplock bags filing, trash sneaking pantomime highlight a theme of this case - the huge divide between whatever book-smarts/ academic theory Kohberger may possess and his seemingly clumsy stupidity in practical aspects?

Anyone with even a limited, undergraduate knowledge of DNA would know that his parents' and siblings' DNA are a 47.5% - 50% match to his own, and that removing only his own items was pointless as police could match his parents' DNA to the murder scene sheath, exactly as happened with his father's DNA.

Leaving his statistically rare size 13 shoe prints with diamond sole pattern in blood may well turn out to be another similarly stupid mistake, akin to turning his phone off just over the period of the murders. Even a 15 year old schoolboy killer knew better and obscured his shoe prints when he committed a very similar, bloody murder - and the schoolboy didn't leave his DNA at the scene or victims' blood/ DNA at his own home despite mutilating and dismembering them. It seems Kohberger was not even as clever or practically effective as a 15 year old: https://en.wikipedia.org/wiki/Murders_of_Claudia_Maupin_and_Oliver_Northup

[My speculation] One of the most likely scenarios for his DNA on the sheath is another big gap between theory and competent, practical knowledge or experience - in sterile technique with regard to DNA; I think he may have put on gloves in the car but then touched a surface with high loading of his DNA such as the steering wheel or car door handle as he got out and then handled the sheath with this contaminated glove. Studies show that car interiors and areas like steering wheels have very high loading of the driver's own DNA, saliva, sebum and mucous. Studies also show how DNA from highly contaminated car interiors transfers to objects taken out of the car by the driver
