It only makes sense to me if PF committed the murder and the very maleable KK was an accessory who agreed to plant the phone data and take some stuff.
Here's my thoughts:
You have to have really close personal knowledge of someone to figure out how best to kill them in a small town like WP. Maybe in NYC you can get someone to kill them on the subway. But teeny tiny Woodland Park: You need to know KB's habits, her routes, her plans. AND you have to keep Baby K safe.
You have to consider where she works: Who is gonna know that better than PF? I mean DOSS isn't going to tell a strange woman on the phone about KB's work schedule.
The ONLY person who would known the details of how to attack her, when, and where was PF. (unless KB and KK texted like besties and I HIGHLY doubt this) It was always his call.
So PF calls the shots. For some *really stupid* reason tries to recruit KK to do damage control. And for a more * stupid reason* she agrees to drive 22 hours that weekend and return the with phone of a murdered woman.
Think about this: KK would have to have left TF Idaho about 1 am Wed, Nov 21 to arrive when KB was at Safeway. When KB was alive.
My surmise is that LE has KK's phone pings all the way along this journey. They know when she bought gas and where. PF may have taken Baby K on T-day, but if KK was involved in murdering KB, it would have to be after the Safeway video, after PF removed Baby K, and without using her own vehicle.
LE surely knows where KK stayed the night of Nov 22, 23, and 24 by her phone pings. And I'll bet it's with PF.
So, KK may not be a First Degree Murder conviction, but she is surely gonna spend the last of her good lookin' years in prison for Accessory Before the Fact and Accessory After the Fact to Murder, and avoiding that is what this ridiculous interview with the R's is all about
