One of the reasons I really want to see solid evidence that Lori participated in a plan is because it appears to me that Chad is a master manipulator. I think it is very plausible that there was no plan at all and Chad orchestrated everything through manipulating Alex. He did not only manipulate Lori and Alex but also his kids, possibly Tammy, MG, JR and many others.
Lori cutting JJ slowly out of his own life shows her callous intent.
-Killed his father (was giddy with delight at LE interview hours later)
-Stopped him from seeing his grandparents.
-killed his sister (who IMO was his main care giver)
-Gave away his care dog-
-Stopped his meds that keep him happy.
-Removed him from his only stability (special school for his needs)
-shipped him from house to house with little of his belongings.
- verbalised to others him a zombie the day before he was murdered.
-told anyone who asked JJ was safe and she knew exactly where he was.
- Asked MEL G to lie to police about having him.
-married the man who pulled all the strings weeks later.
-Told nate eaton in hawaii people were praying for her children and she replied...
thats greeeeeeeeeeeaaaaat.
-admitted to sister in jail call that she knew the kids were dead before she married chad.
thats just off the top of my head.
slam dunk the funk.

Her goose is cooked.
