As far as the condensed timeline the morning of the 911 call.
I am gathering from the reports that 1. the man in the truck called 911 for the older brother /gave him a ride back home (2 blocks) 2. SC knows about the next door neighbor who heard voices as that is part of his account that morning to LE
3. The real uncles LR/RR came on the scene after police arrived.
The report that has SC relaying the neighbor's voices story has bugged me, since the family were not allowed to search after police arrived, and the uncles arrived after the police arrived, so how could he have told LE that? Could it have been SC who knocked on the neighbor's door at 8 am? She could have been confused, or simply never paid enough attention to who was who around that house. This would be one possibility to solve some timeline issues for me.
I would imagine this in my scenario of the timeline....
SC goes to wake Isa and finds her not there
He goes to the boys room and wakes them
Oldest runs into Isa's room and notices the window and screen
SC and odest run out to back alley where they look up and down
SC knocks on first door he sees in a panic -- neighbor's door
She tells SC about the voices she heard
Isa's older brother runs runs east down alley looking for Isa SC calls RC at work
SC goes back in home and calls RC ---
SC calls 911 @ 8:14
Oldest runs into woman from 13th and man in truck--- man calls 911
Man in truck gives oldest a ride home...
When police arrive RC, SC and the boys are all there
The family remains together for the day in company of LE
I noted that the witness at the store, EC, reportedly witnessed the young brother looking for Isa an hour after the 911 call (9:15 or so) That does not really jive with the reports I have seen, as from what I saw the family was not allowed to search after police arrived, so I really don't know how this can all factor in.
