I followed the case through every type of venue possible, including here on WS.
Dominic Casey does say in the book that KC changed Caylee from swimsuit to clothes after she was murdered. He was also bound by a confidentiality agreement with KC, separately with JB, and another one with George and Cindy. The scheme by JB to blame George was concocted in the beginning, yet there were several times KC stated that George never touched her. He describes over $300k missing money from defense fund, JB making lewd comments to KC, how JB manipulated KC into sneaking picture albums and videos to him and that JB even said once that KC killed her kid. He discusses the psychic thing also.
I found the book interesting and it shed light on some of the things that puzzled me during the case. He does address the duct tape and explains why it makes sense that Caylee'sbody was in the trunk for 5 days.
If anyone reads the book, do it carefully because all of the concerns mentioned here are indeed addressed.
I may be in the minority, but the book does not come across as him just carelessly throwing a bunch of opinions out there. The 31 days are broken down quite well, and yes, even the flurry of calls is explained. While he wasnt present during Casey activities, his evaluation makes sense and is plausible. He certainly has more knowledge about things than anyone here does.
