It's not clear what her phone records say about where the phone pinged prior to the 23rd. She obviously made an effort to turn off the Google tracking so it's also possible that she did the same with her phone.
I was curious about whether a phone would ping while turned off so I googled. Unfortunately, I got conflicting answers. One mentioned removing the SIM card would prevent any tracking. That makes sense sense unless there's some other backdoor device in phones that connects to towers, which is possible. Here's something I found from a detective which addresses the issue of the battery, as well as a little bag you can put your phone in to block all signals:
Can the police track your cell phone if it's turned off?

I know nothing about tech so I have no clue. I know I read that KK's phone was a Samsung and you can do different things with different phones (like remove the battery) but I don't know her phone and model. I suppose we'll learn more about her phone(s) and phone records at trial. Until that time, I've seen no claims of technological proof that her phone was in Idaho prior to the 23rd. So, what we have are people she's close to saying that. Given the shady nature of the flying monkeys who have been doing her bidding, I prefer other evidence, be that tech/phone records and/or local pings or her caught on some local CCTV. Until I see that, I'm open to the possibility that she may have been in Colorado. Considering the fact that she traveled thousands of miles, in a couple of months, to stalk Kelsey and, by her own account, came close to murdering her (pipe & baseball bat - HER bat, btw) I'm of the opinion that she was very f-ing serious about wanting Kelsey dead.
None of that absolves Patrick Frazee of anything.
Oh, and, if the neighbors security cam showed Frazee at Kelsey's, it should also show KK when she arrived and left the scene, right? If such footage exists, it could explain LE being certain KK didn't enter Kelsey's home until the 24th.
