Just finished the whole thread. Pmerle00, I am so sorry that you and your family are having to endure all of this. Please know that we are all fighting right here with you. We need to find Papaw! The Websleuths community is full of kind hearted people, and I know that many of us have really enjoyed learning about what a great man your Papaw is. Thank you for sharing these little glimpses of his life with us.
I kept a running record of questions I had as I was reading...many of them got answered, and many points I wanted to make got made by you guys just as I was coming up with them. Great minds think alike, and the bouncing of ideas off each other is resulting in some great theories. Keep it coming.
I agree...Papaw didn't seem the least bit interested in technology. Although I have heard of people going "off the grid" to start a new life (and I guess it's possible), I don't think that's the case here. I don't think he would have taken his phone and taken a Sim card out of it so he could get a new one. Speaking of that...what cell service does he have? For example, Verizon doesn't even use Sim cards (that's the carrier I use). I'm not sure if that's important, but it may rule out some theories to know that information.
I'd be interested to know if he made it home in a reasonable time frame. The receipt and Walmart cameras are timestamped, no doubt...I'm wondering if he came straight home, or went somewhere else. I guess for now, we don't know. We may never know.
Regarding the license...it could be a coincidence it's missing. A crazy coincidence, but...I know I've dropped my license without knowing it before, only to have someone tell me I dropped something. Maybe it got dropped somewhere. Far fetched since we don't think he used the license for anything, but...I don't know. Is it confirmed that he did NOT use his license in Walmart? It'd be more likely that it got dropped/lost if he did in fact use it, since it would have been removed from his wallet for a bit.
I, too, am interested in knowing how old that blood is. My papa also had a shed out back, and my grandma rarely went out into the shed. If there was blood in it, she wouldn't have been able to narrow down how old it was...there would be months at a time when she never went back there. I hope LE looked into how old the blood was, because if it is old, it could just be a red herring in this case (although now that I think of it, who would leave blood in their shed like that? Probably not Papaw, it sounds like he takes pride in his hobby, and his shed is his workplace for that hobby). Interesting that a dowel had his blood. I'm wondering how large this dowel is, and how the blood is on it...dripped, smeared, etc. Could be another red herring.
Papaw definitely is smart enough to leave the wallet and keys to send a message, signal that something is not right. I wouldn't rule that theory out at all.
My last thought...because the keys were in the shed, and the shed was locked...IF Papaw is the one who closed that locked door, and ASSUMING he didn't accidentally lock himself out (a fair assumption, seeing as he's never done that before), he had to know that there was no way back into his house or shed without his keys. I think that is a crucial point to think about. Of course, it could be that someone ELSE left the items and closed the shed door. But if it was Papaw...he had to know he wasn't going back into the house or shed.
Everything is MOO, IMO, etc.
