There are so many comments regarding the delay of MM to file a missing person's report and comments about SB cleaning the Fallbrook home before the search warrant was issued, that I just wanted to give another angle to the possible reasons why. It's all MOO of course!
By all accounts, Summer was not the easiest person to get along with. MM testified to the falling out he had with her and the rift it created in the family.
And from Patrick McStay's book “McStays, Taken Too Soon”
A witness actually saw Summer light into Joey's mother one time, telling her “you will never be one of us, you will never be part of my Circle of 4.”
So IMO relationships were strained.
Then, a few months before the disappearance, Summer McStay filed a Child Protective Services complaint against McFadden, according to Joseph McStay's father, Patrick McStay. "I have evidence that there were threats made, after the CPS report, to Joey and Summer." He told CBS News 8.
According to PM, McFadden told JM that Joey needed to shut Summer up or he was going to do it for him.
I think MM and SB might have thought the family needed/wanted to get away for a while due to the intense CPS situation. Not going to LE sooner and cleaning the house were, obviously, not good choices. But they thought they were coming back. Who would EVER think this would be the outcome?
As far as Chase goes:
McCargar testified that Summer was territorial but she had good intuition. She was protective of Joseph and the kids. It angered her when Chase would bring up how she wasn’t raising her children properly.
(That would anger me too. Just who does he think he is)?
According to PM (his book):
Chase and other friends of Joey's were often greeted by Summer telling them exactly what negative things she thought of them, or their unwanted opinions.
(Can't blame her).
Chase has said so many negative things about Summer. His disdain for her has to come in play somewhere when it comes to motive. That's relevant IMO.
I just wish the jury could hear them all.
All Just MOO
