I wanted to explain my thought process re: the locks, and locking, of the Chambers' house and the previous questions I'd asked as to what type of locks were on the home's exterior door/s.
I'll assume MC had the home and shop locked when he went to WalMart. I don't think anyone knows, or would ever know, if that was a fact.
MC went into the home after returning from WalMart, putting his purchases in the bedroom/bathroom and throwing the receipt into the bathroom trash. We don't know if he stayed in the house any length of time, having some lunch, or whatever, before he went out to the shop.
One of our VIs was able to confirm to us that MC usually did NOT lock the house when he worked in his shop, and that he would have at least one of the home's garage doors open for when Becca would return from her day's work.
On the day he disappeared, MC obviously went out to his shop, and left his keys and wallet in his habitual place there, and became injured somehow, leaving drops and a pool of drops of his blood on the floor.
If MC had left the house unlocked when he went out to the shop that day, how did the house become totally locked up (as was the shop)? To my, and it's MOO, MC himself was ambulatory after his injury and locked his home up himself before leaving the premises. If he was forced to leave with someone else, would that person LET him lock everything up, and why? I just cannot envision an abductor, thief, murderer, or whoever that person was, take the time to do those things himself. (or themselves) And why take the time to allow MC to do so? Did MC or the perpetrator/s take his keys, go lock the house up, return the keys to the shop, THEN make sure the shop man door was locked before leaving the property? Why?? It's all driving me nuts, but these are just a small part of my thought processes.
