If BK had visited the victims house previously and while they’re connected to their Wi-Fi, he would automatically connect if close enough another time correct? On the other hand, if BK never actually connected to their Wi-Fi but was close enough where their network was an option, would LE see history of the victims wi-fi? Apologies if I am making no sense- Still haven’t slept!
No!
(Sorry for the exclamation point).
No one "connects" to your wifi. Your device "reaches out" (a handshake protocol).

THEN, unless you have a password to that device, it's a one-way thing and there's no two party authentication. So, my router clearly knows my neighbors are there - but SO FAR, no one has hacked our router and no one has the password (except our kids - who will show up as connected).
YES, your router has records of who has driven by your house (if the range of the router is far enough). Some cheaper, older routers keep nothing but most modern routers keep lots of records. Cell towers, I believe, keep a permanent record - routers would need to be taken and tested right away. So whether your router contains yesterday's info, depends on the router.
Police were at 1122 by noon-ish. I'm sure one of the first things the forensic unit did was take any routers (and victim cell phones) and go start the process. That's one reason Kohberger turned off his phone - he knew he had been by before, perhaps had researched that one aspect a bit more (he's no whiz in this department, IMO).
Could I please trouble you to explain consumptive testing? All of the below is pure hypothetical speculation on my part!
Hypothetically, if there was visible blood on the sheath, would swabbing that visible (in my speculative hypothetical) blood be considered consumptive testing?
And continuing in my hypothetical, if that swabbing found a blood mixture, is it possible to separate the DNA in a mixture if there were two (or more) contributors to the visible blood on a sheath?
All of the above are hypotheticals to try to better understand what others may already have an understanding about.
TIA for you patience educating people like me!
It's when the piece of evidence is partly or entirely destroyed in order to provide additional evidence. Typically, evidence can be swabbed carefully, but not subjected to any process that would alter or destroy it - without a ruling from a Judge.
The Defense has not asked for additional testing, because if that happens, the Judge will likely have the testing done at an independent lab with representatives from both sides - and the Defense has to think about whether the results will be the same. If they are, then it's double evidence against their client. IOW, it's a gamble.
An example would be taking a tool that splits a core of the sheath off from the rest of the sheath - or takes the snap off to get further underneath it (possibly a good place to find more user DNA). Usually, cores are taken from various parts of the sheath - so that it will not look as it did when it was picked up as evidence. That's why the Judge has to okay it.
The State already has what it wants from the sheath - so they won't ask for it.
