I don’t think Cindy or George or Lee had a single direct thing to do with Caylee’s murder but all three of them were very active in the cover up and the cover up probably began on July 16th or July 17th, 2008.
By that time they all knew Caley was gone...and clearly other family memebers had warned them if Casey didn't tell the truth she could get the death penalty......and SOOOOO do as families such as this often do ...they were going to do all possible to keep Casey from the death penalty.
This family went into big time "co-dependant mode"..just as they always had to do regarding anything Casey brought on them.... Only this time her life was at stake.
The family has had a lifetime of chaos it's 'familar' regardless.. and people find 'comfort' in the familiar even in abusive and severly dysfunctional homes. ...they'd been there with Casey many times before...it was "normal" for them...and Casey was after all family.
The police were still looking for Cayley up til Dec....so I'm not certain of the dates they actually accepted the realities....but as you say there was a cover up for Casey, they weren't about to loose her too.
I'm going to watch some of the videos of Casey as she learned she wasn't going to go home today. I've seen shots of her, hair down and makeup on already to "go out to meet the world". And not surprisingly she "dressed" for it. Camera's would be rolling and the star would emerge. But I guess it didn't happen so I want to see her as she learns this.
You're absolutely right. Go back and check a couple of the old YouTube videos (there are zillions) of the psycho interacting with her family. They would do anything for their sick brat.
