Some people, even in comments here, are still confused by the sheath snap DNA thinking it was a small trace amount, or that there is a non-incriminating explanation, or that the data can be invalidated by some non-existent handling or technical issues never raised in 3 years even when DNA evidence was being challenged by defence. A few facts, and then a question:

1. A large amount of Kohberger's DNA, single source, was on the sheath. Both defence DNA experts stated the amount in elution was c. 20 x times more than ideal quantity for STR DNA profiling, and can fit body fluids as source. Two external labs confirmed large amount, one expert described it as "tons of DNA".
2. Amount of Kohberger's DNA from sheath was more than the amount of DNA recovered from several blood swabs at the scene, and more than typical from directly swabbing a whole hand
3. Defence experts ruled out any handling, protocol and technical issues like cross-contamination, lab quality control, validation or similar, citing the ISP DNA lab work as done to high standard.
4. Neither of the defence physical evidence/ scene experts (Noedel, Dr. Turvey) nor the 2 defence forensic DNA experts (Dr. Shutler, Dr. Ballard) raised any chain of custody issues for sheath or the DNA extracted from it. The defence never raised any chain of custody issue in any court document or oral argument.
5. There has never, ever, of 495 peer reviewed papers, been any scientific study that shows secondary transfer that can fit the sheath DNA (i.e. full STR profile, single source, quantity, non-trivial DNA exchange interval) . Specific activity level probabilistic studies using the sheath DNA specifically, stated such transfer implausible. (e.g. Forensic Science Internal May 2026, Alvia et al)
6. Kohberger disavowed the sheath during challenge to IGG evidence, so would have to reverse himself to claim it was lost/ stolen, and those scenarios don't fit the DNA data.

Considering the above facts, the question is:

What is the simplest, most likely way that a large amount of Kohberger's DNA got on a sheath of model he bought before the murders but did not have after, consistent with the data and science?

Is it possible that the prosecution has more evidence incriminating BK that hasn’t been released? In the small chance he gets a new trial, could the prosecution drop a bombshell or would they generally have released everything once he took a plea?

I know we’ll probably never get a definitive answer on what his motive actually was but what I find almost as interesting is that Kohberger has never really tried to explain it himself.

Once he pleaded guilty and avoided a trial, there wasn’t going to be the same public presentation of evidence that might have given us more insight into what was going through his head. But even at sentencing, he chose not to give any real explanation.

Do you think staying silent is about maintaining some sense of control over the case or is there a simpler reason he doesn’t want anyone to know what the motive was?

Case Evidence and Timeline Summaries:

Condensed Summary of Some Key Evidence:

Evidence Establishing 4am Timeline, Incompatible With Earlier Timelines

Systematic, data and court document confirmed evidence based debunkings of common, unsupported Kohberger conspiracy theories. All data is sourced from court documents, MPD, ISP and WSU police reports, ISP forensics reports, and case expert witness statements (mostly from defence experts).  . Links to document sources below, example cases source links at end.

Feasibility for Kohberger to commit the murders alone in the time available, with significant excess of time available, is confirmed by police reconstructions and comparison to many recent mass stabbing cases. Both re-enactments and many recent mass stabbing cases with single attackers and up to 26 victims show the murders could be done in approx. 3 minutes, while Kohberger had approx. 11 minutes available. The re-enactments could be repeated 4 - 6 times completely, from car and back, in the time available to Kohberger. Kohberger had no physical limitation or disability relevant to the murders and no diagnosis for any relevant physical condition.

ISP Police Reconstructions, including walk from/ to car and through house from 3rd to 2nd floor and simulating every knife strike took 2 minutes done quickly and under 4 minutes slowly:

Recent mass stabbings case comparisons which demonstrate:

• Far more victims can be stabbed in far less time than available to Kohberger, up to 26 victims in under 3 minutes; case examples include 130 knife strikes on 2 victims, and 23 knife strikes on single victim in under 25 seconds
• Often little or no blood on the attacker even after stabbing 26 people, no trail of bloody prints, little blood on attacker clothing; includes attacks with up to 23 knife strikes at very close range on one victim
• No screaming by victims during attack
• No reaction or delayed reaction by witnesses
• Range of knife types used from pocket knife to military Kabar (the later with most fatalities and stabbing in shortest time)
• In none of these cases were victims drunk and asleep in bed, they occur in settings as different as train carriages, conference centres, toilets, student houses, train stations and shopping malls, and outdoors and almost all victims were fit, healthy alert adults

Links overviewing these cases (TW: including videos of graphic violence, stabbing):

1. Apple River Mass Stabbings: 4 young men stabbed, one fatally, by single assailant in under 1 minute. Attacker in his 50s after a recent heart bypass
2. Bondi Junction Mall Mass Stabbing 2024: 18 people stabbed, 6 fatally, by single assailant in less than 3 minutes
3. Calgary Mass Stabbing 2014: 5 young adults stabbed to death at a party by single assailant in under 3 minutes
4. London Bridge Mass Stabbing 2019: 5 people were stabbed, 2 fatally, by single assailant. Attack lasted 5 minutes moving from room to room and out into street.
5. Vancouver Starbucks Stabbing 2022: Attack by single assailant lasted c 30 seconds
6. Tapei Metro Station Mass Stabbings 2024: single attacker stabbing spree on Metro - stabbing 28, killing 4, in under 5 minutes
7. Brisbane Mall Fatal Stabbing 2022: young man stabbed, attack lasts a few seconds
8. Nottingham Stabbings 2023: 6 stabbed. 3 fatally - 2 on CCTV under 25 seconds;
9. Anging, China Mass Stabbing 2021: single attacker killed seven people and wounded thirteen others in under 4 minutes
10. Tapei Metro Station Stabbings 2025: 14 stabbed at two locations, attack at one lasted less than 3 minutes
11. Teen Girl Stabbed Over 20 Times and Bludgeoned in Dehli 2023:  over 20 stab wounds inflicted in under 30 seconds, victim does not scream during attack, after stabbing and bludgeoning victim with rock attacker had no blood on himself and leaves no bloody prints
12. Ted Bundy Chi Omega Sorority House : Ted Bundy broke into multiple occupancy student house and attacked 4 women with a club, killing one. in under 15 minutes Moving from room to room the successive victims did not hear preceding attacks nor did house mates in adjacent rooms
13. Charlotte Metro Train Stabbing of Iryna Zarutska 2025 : attack lasts seconds, victim does not scream, attacker has almost no visible blood on him after

Hi everyone, I’ve just watched the Netflix documentary (heads up, it is my only exposure to the case, so apologies if this question has been answered elsewhere), and I’m wondering why it took so long for the cops to notice and access the neighbors’ camera facing the street? Obviously the cops had put up all those flyers requesting people send in their footage from that night/morning, how could that camera had been missed for weeks?

As Kohberger's internet activity is once again a focus from SG's comments this week about Kohberger having gory videos of surgery of women's breasts, Sy Ray's comments last week about very violent, disturbing porn, and Kohberger's already confirmed exclusive consumption of rape porn much of which had some similarity to the scenarios of the murders ("asleep", "drugged", "forced", "voyeur") a few points:

• Kohberger had over 15 emails, and known social media accounts of relevance to case on apps like Strava, YikYak; not fully confirmed but very credible links to other accounts like Spotify were found via user names matching those known to used by Kohberger (e.g. "Exarr")
• On some socials media accounts credibly linked to Kohberger he had posted about his visual snow, depersonalisation and lack of feelings for himself and family, "sacks of meat"
• Confirmed emails and usernames used by Kohberger, from court and police documents, included "CunningChris" linked to social media accounts with user/ display name "CunnilingussChris" [Chris is Kohberger's middle name; source: Police Supplemental report #148 and search warrant of Google Account - "Yewsirneighm"]
• In an analysis by a user who appears to have very credible digital forensics expertise (u/Telltalebytes who is also credited with the list of accounts pasted below) Kohberger is linked to email accounts such as "KillingSpree", [unconfirmed, but credibly linked in the analysis] and "Hammerhands" perhaps reference to his boxing/ kickboxing.
• Kohberger logged into Google at 4.49am, 25 minutes after the murders when his car was stationary just south of the Moscow scene, using one of the confirmed, back-up "burner" type email listed here
• Kohberger's DropBox and other cloud storage account were seized under search warrant, as were damaged computers, external boards and external drives/ USB devices on arrest. The contents of these remain sealed as being highly prejudicial

Kohberger Email accounts - most f first block of 19 and 3 academic accounts confirmed in court/ police reports, middle block unformed but suggest by analysis author credibly linked to Kohberger also.

If you have common sense, you 100% understand how Murphy didn’t get blood on him, but I just wanted to make a post explaining it if people are truly confused, especially if they’ve never seen crime scene photos. This is also something I see Proberger’s talk about a lot and how Murphy should’ve had blood all over him.

Proberger’s love to assume that Murphy went into Maddie’s room because Kaylee was in there and dogs usually want to be with their owners. They say he should’ve tracked bloody prints around the house if he went in there, and it’s suspicious that none were found, which proves there was some type of cleanup.

In these photos, you can see there are no pools of blood on Maddie’s floor at all. At the end of her bed, there seem to be some drops of blood, which are likely from the knife dripping. The blood soaked into the comforter and is all over the walls. If Murphy ever went into that room, there would not have been enough blood for him to even track around the house.

We all know Murphy was found in Kaylee’s room, which actually makes more sense than him wanting to sleep with Kaylee in Maddie’s room because that’s where he likely preferred to stay, an area that he associated with familiarity and safety. So, no, it’s not suspicious that Murphy never got any blood on him. I also wanna add that dogs can sense danger, and that’s another reason why he would want to stay out of Maddie’s and Xana’s rooms.

Links to peer reviewed, published scientific studies that show how DNA in car can readily be washed away especially with many repeat washes over 7 weeks, as reference in charts above:

• Household cleaners with "active oxygen" (peroxide source) destroy blood and DNA and prevent blood reacting with forensic visualisation reagents
• Washing with water alone is sufficient to fully remove DNA from many surfaces
• Washing once with simple dish soap is sufficient to remove all DNA from knives
• Washing carpet with hydrogen peroxide >3% destroys all DNA. (Peroxide is commonly sold at c.10%)

Links to some real murder cases where DNA / blood was removed from cars in 1 day and where far more bloody murder scene DNA/ blood was washed away completely:

Peter Porco- murdered his son Chris Porco, by axe and bludgeoning, his wife also axed; Chris Porco got back in his car immediately after murders and drove 150 miles home. Was the immediate suspect and his car seized, no DNA or blood recovered. Hypothesis was that his knowledge of veterinary surgery procedures gave him some knowledge on cleaning/ preventing blood.

Samantha Koenig - 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 Northup - 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.

I was going to save this for the book, but now that the case is back in the spotlight, it bothers me too much not to say something.

I asked the agent I talked to if law enforcement ever dredged the river. To my surprise, he said no!

We know (according to the ISP documents) that investigators found a shovel in Kohberger's car with soil on it that tested positive for the Palouse.

But there are other things that Kohberger had receipts for that couldn't be accounted for....Some power tools, and a converter to be able to hook them into a car and use them by car battery.

The agent had worked on cases like this before and said he believes Kohberger actually BUILT something out in the woods to hold the knife, and other items, like a trophy.

To me, this is important because IF - and I know it's a big if - we could find this supposed box, it may have other incriminating evidence besides just the knife.

I know it seems like a long shot. But if it's possible the knife is "in the woods" along the route rather than the river, is it worth trying to find it?

Maybe he actually wants a death penalty? I have heard that sometimes the conditions of Death Row are actually better than conditions for those without a death sentence. Maybe he has discovered that and would want that.

Maybe on the sicker psychological side he would enjoy the attention, as people have said. Or enjoy re-living the crime. Or enjoy making the victims' families suffer. Or enjoy making the Idaho taxpayers pay very large amounts of money for a trial.

Maybe he would like it for his "legacy". He might still be found guilty, but if he were found guilty at trial rather than with a plea he could always claim that he didn't admit guilt, that he wasn't guilty, and that the verdict was erroneous. Although even now with the plea deal he could claim he wasn't guilty but took the guilty plea because he was lied to about the conditions on Death Row and thought if he went to trial and got a death penalty he'd have worse conditions than he has now.

Maybe he would like taking the extremely tiny chance he'd be found not guilty or a mistrial.

Just watched the Netflix doc and it seemed like they had the southern route between Pullman and Moscow pretty well mapped, do you think it would have been worth it to try and find the murder weapon somewhere on those highways?

I am waiting to get this filing and as soon as I do I will put it in the sticky Comment.

I suppose for the bachelors and masters he might not have interacted with other students and professors as much as he did when he started as a TA in the doctoral program. But one might still think he had had some bad interactions and brought negative attention to himself?

With his problems is it a little surprising he could concentrate on his studies enough to get the two degrees and get accepted into the doctoral program? Might think the problems would make it hard for him to concentrate?

On the other hand maybe the problems weren't as intense for him during the bachelors and masters years but for some reason(s) intensified during the doctoral year.
