The thing that will always shoot those theories down is the fact that she still had her phone AFTER the clean up. If she took pics, that would certainly be on PF's phone. Things deleted seldom stay that way.
I had the thought maybe she would have taken pics, as well. We don't have all the real "evidence", per se.
As far as the exhaustion - she maybe drinking one of those Starbucks double triple quadruple espressos.
Same here with the IMO and speculation.
She had her phone after the cleanup, but only until about 12/4, IIRC. I think when PF got arrested, she told her ex-husband she had lost her phone and had to buy a new one. I know that even if the phone is gone, LE can still work with the phone company to get her call/text log. What I don't know is if LE can access the content of texts or photos that were only on the phone or were backed up somewhere without LE knowing where.
Not really relevant except as evidence of KK's character, perhaps, but I wonder about her relationship with her ex-husband. They're divorced but they still share a home, OK, I can understand that happens. I don't understand them getting along well enough to make that work, but she still had to hide her relationship with PF from him. From his brief comment, it sounds like her relationship with PF in 2016-2017 with PF contributed to the breakup. However, I don't understand why she would still need to hide a new relationship from her ex and apparently most of her family. Only a few friends knew about PF.
I also don't understand the texts. She sends a fake text to MG in case her husband reads her texts, but what about the regular communication (calls and texts) to PF? Did she regularly clean up her phone log and delete everything?
Just seems odd, like so much else about this case.
