IIRC, MC & RC had only lived there a few weeks/months prior to HC missing. I wonder the condition of the screen door prior to their moving in. which made me just think of something else....wouldn't it make sense when RC & MC were moving into the MH, that the side door would be the best to use to move in all the furniture, being that there is a ramp there? maybe the door has been like that since they moved in, since they weren't living there that long. trying to take everything into consideration, I think it is awfully strange, that RC offers to LE and news media a way that the wood door got unlocked. (that was my very first red flag) as far as the cinder block is concerned, I think it was there all along and that info was given to LE as a derailment. I don't think a perp placed it there as a way to gain access to getting the wood door "bumped". If it is late at night, you don't know who is outside and who is looking, why would a perp go looking on the property for something to prop open a door? (given that the cinder block was with the others by the shed) Why take so many chances in getting caught? (leaving the kitchen light on, going into the very same room that MC and JR are sleeping in to take HC?) none of it adds up to me. IMO
I am also betting LE asked some of the neighbors about that screen door, may have even asked the landlord, if that door has been propped open for any certain amount of time.
