Framing someone else in a serious crime like an abduction/murder is nothing new. Now under the theory that a vehicle was not used and DR is responsible, how do you explain the last known footprint other than that it is planted to throw them off the trail?
I can't explain it-which is why I have dwelled on it for so long. On the surface it appears to me his last footprint indicates he entered a vehicle IMO. But that leads back to the tire track debate.
From your posts I gleaned that you theorize that when Kevin drove through the farmstead, this gave DR an idea to go back on the road and plant the footprint very closely to Kevin's tire tracks. This means DR must have some knowledge of the dynamics of a footprint left by JW in entering a vehicle. And where would DR's footprints be in doing that? IMHO, it seems a stretch of the imagination that the footprint is planted. My only thought is that JW may have made a break for it and the perp grabbed him and lifted him off the driveway.
