I want to say it was made public fairly early on that David usually did not lock his vehicle. It is a fairly common practice around here to not lock your vehicle. Everyone laughed at us coming from the more heavily populated North because we lock everything, including the gates to all our fields.
We did have the last laugh on that subject recently, as there was a police chase that ended back here in our holler with an ensuing manhunt. People were worried about the fugitives taking off in their vehicles because they leave them unlocked with the keys in the ignition. We didn’t have that worry!
I have seen it theorized that David locked his truck that particular day because he had tools of value in it. It would make sense then that he locked it as it was parked in the Dollar General lot right next to the main road.
If I were going to leave my vehicle parked because it was not running or having some sort of issue and walk home, I would take what I absolutely needed with me, lock the vehicle and start walking.
In my opinion, if his keys and wallet were found with him, it would be very telling. In my mind, it would rule out robbery, especially if the money he had withdrawn recently from the bank was recovered with his remains.
For those who think his walk was long or far because his body was found over a mile and a half from the Dollar General, that distance is not unusual for this area. My closest neighbor on one side of my property is 3/4 mile from my house, as is the neighbor to the rear. Many of us walk our properties regularly to check livestock, fence lines and to make sure nothing is going on that shouldn’t be. I have a neighbor, who was 76 when we moved here, who walked 3 miles in an ice storm to check cattle, even though he has both a four wheel drive truck, four wheeler and tractor. It is a way of life in this area.
