Donna's lack of tears and flare of anger when the judge read out the jurors' decision was for show. For people who still believe her story. Likely her grandchildren and people who testified on her behalf ( without being paid) and who have likely chosen not to follow the news as family members / friend are moved through our justice system. It may be impossible for them to reconcile what they want to believe and what is happening. Cannot imagine losing your dad, losing family members to jail, and potentially your surviving parent while people put you at the center point for this tug of war. As we could see during this trial, it was not about a tug of war over the children it was the ego of this family who did not want to lose this battle with this brilliant man - therefore the critical timing of the murder - they did not want to be caught with what DM was going to unmask with his next set of motions. Think this versus well fit what we have now seen and lift any guilt these young, almost men, may be feeling with the story that has been seen up until the evidence of this trial. Of course/ my theory, opinion only.
