Regarding AA and the assumption that Gannon had been murdered at home on the afternoon of Monday 27 January after TS return from her outing with Gannon.
I am recalling from memory, don't depend on it entirely, that Crime scene people paid at least 3 if not 4 or 5 visits to that house following Gannon's disappearance.
Dan May went in there on at least one occasion.
There HAD to be something about the nature of the blood found that led them to state their belief that he died there on Monday afternoon, as opposed to the blood being from the Sunday night or another occasion.
FBI were involved and they have access to first rate laboratories.
I think they must have been able to time the blood spillage they found.
When they discovered his body and stated it changed everything, perhaps they were merely referring to the nature of the injuries found on his body, blunt instrument and gunshot, possibly.
I am assuming TS was outa that house like a bat outa hell once Al returned on Tuesday morning and Landen arrived on Tuesday evening.
Can we assume those bloodstains were found quite quickly after the murder? If so they could be timed from the blood itself through laboratory testing.
I didn't see Gannon returning with LS.
I do remember the Sheriff's deputy saying she did not disagree with RD's footage and it was part of the story but not the entire story and I remembered they received several sets of footage from other neighbors too.
He may have been unconscious in back of truck, hidden and wrapped but still alive, perhaps unbeknownst to LS immediately...
It's hard to know the truth here.
And I agree it appears to be an act of total insanity to bring the child home knowingly to kill him in his own bedroom in the family home.
BUT, LE must have had reason to believe that is how it happened from their own forensic investigations.
