New poster here.
I wanted to give my thoughts on this very strange case. I strongly believe if law enforcement had anything on her fiancé, he would be done for by now. I also find his behavior very odd but we really don’t know the extent of their relationship. I think if he snapped and murdered Kelsey, he wouldn’t have drove with a dead body in his car to Idaho and send text messages 3 days later after she was last seen. Even if he buried her body somewhere nearby, I just don’t think it’s really plausible to think someone would take the persons purse, keys and phone 800 miles away only to send messages to himself and her boss days later. I really really don’t.
They had enough on him to support probable cause that evidence of a crime was present on his property and/or in his vehicles. That's significant and not even a tiny bit close to nothing.
He may not have driven with her body to Idaho. Posters have pointed out the improbability of that, which enlightened me. It is more likely he dumped her somewhere close to home and then later drove her phone to ID to create a false trail.
And of course it is probable that a murderer would go to great lengths to hide their involvement and mislead LE. If you have followed cases like this for any length of time that would become quite apparent to you, I believe.
Would it be plausible that a woman would wear diapers and take several gas cans along so she could drive for days without stopping in order to kill the girlfriend of her ex? (Lisa Nowak).
Would it be plausible that a man would ambush a family, murder most of them and the family dog, dismember them
And hide the pieces of their corpses dozens of feet high, shoving them down the top of a hollowed out tree? (Matthew Hoffman)
How about going out of town and staying in a hotel, but then disabling the hotel cameras and driving back home to murder one's spouse, and then back to the hotel, in a 169 mile round trip lasting about 8 hours? (Jason Young)
What wouldn't a perp do to escape justice for murder?
