FWIW...in the 911 call I noted Misty trying to explain to the operator about the block first says something about it being on the "floor" IIRC, then, she expands to explain on the ramp, IIRC. Maybe nothing...maybe something...:waitasec:
We can only speculate on the little shreds of information we have, but, when/if we learn the as-found status of the solid door I think it tells us something.
One props a doorway (2-doors in this case) open for a variety of reasons.
1) One will be carrying a heavy/awkward load through a self-closing doorway by oneself without the assistance of someone to help hold the door...or even if one has someone to help hold one door if/when the 2nd door swings in the opposite direction as I believe these doors function.
2) One wants to carry an awkward load through same without damaging the load or the doorway
3) One wants to naturally cool a room
4) One wants to naturally ventilate a room
5) One will be carrying several loads, even small-to-medium, through the doorway and wishes to do so quickly, and/or, without the nuisance of operating the doors.
...anyone wanna add 6, 7, 8 etc.?
...and of course, the list gets longer to compare the reasons only 1 door would be propped open and the other would be ajar.
...and plus 1 that for only 1 door propped open and the other latched
IMHO, We can speculate on which of the above is the more likely motive based on the manner in which doors were propped. And based on the motive..better speculate on who was responsible for propping it open.
Early in the case we spent some time discussing the block itself...and...upon searching this afternoon I cannot find a thread dedicated to the block. Sooo....I'm off to create one and will include the option to discuss whether or not it was solely responsible for holding both doors, or if something else was employed. I see the close connection w/ this thread, however, IMHO, the prop itself is as independently important to solving this as is "How [Did] The Side Door Get Opened". Hopefully we'll see it explored enough to stand on its own merit.
