This is all pure speculation, but I really think that the area where KY was arrested in Edwards needs to be searched more. Looking at the timeline of events, I think that there was enough time between when they left the party and when KY was supposed to report to work for him to have driven down to Edwards with JR and then back. There is even enough time for him to have gone back to his grandfather's home to shower and change, which would explain why evidence was found there as well as the trailer in Edwards. I think that KY heard that JR was reported missing and then decided to burn the car. If you look at a close-up of the map, the car was left in a little alcove type of area just beyond the bridge on Blue River Road. I think he left it in that location to try to throw searchers and police off the trail and to keep them focused on the area in Kansas City. I'm curious as to how they knew to find KY in Edwards. Did someone report that he went down there? Cell phone pings? Again, this is all speculation on my part, just trying to piece together what little information is available. It amazes me how much time KY had to destroy evidence, and how he's been able to get by with so much for so long. I think that he has definitely killed before, and more than just once or twice. I keep seeing that he passed a lie detector test back when Kara was first reported missing, which in my opinion means absolutely nothing. Gary Ridgeway (the Green River Killer) passed a lie detector test as well in the 80s and years later it was discovered he had killed nearly fifty women, if not more. I hope this time they can gather enough evidence to put KY away for a long time. I fear that if he is allowed to go on this one there will be many, many more people hurt. Just looking at his mug shot and the lack of soul in his eyes is chilling enough without adding in all the other details.
