I suggest everyone to re-watch the full interview with this thought in mind: EG's statements may be literally true (and perhaps she is practicing for a polygraph.)

What if Lucas accidentally died sometime after February 11 when he was last seen. EG is genuinely grieved, but knows if she reports it she will definitely lose her kids, and maybe JH. So, she decides to get someone to help her. Suppose she calls someone from a payphone and that person is the black smoking man who comes to the house. He agrees to help her. Recall there is a white SUV backed up to the driveway on Feb. 13. I am not sure whose vehicle this is (and Kansas does not open motor vehicle registration records except to law enforcement).
If that is the theory, she makes it through the entire interview without blatantly lying (except maybe about the identity of the people she claims she saw, but maybe she did photograph two people walking down the street for cover). She did not "hurt" Lucas (accident maybe with drugs). She does not know where he is (only her conspirator does). Lucas "fell asleep" when EG did after her shower (and maybe did not wake up). It was that emotional point in the interview for her at which she ended the interview. His death was too real to her. She may be lying about the bruising, that it is all roughhousing, but those are not lies that would implicate her in what happened to him and she can deal with that. Perhaps we believe her grief, but this theory explains both grief and wrongdoing.
JH has been silent. He is last recorded saying he believes his son is alive a week ago. Perhaps his silence is also grief and instructions from LE that the less they let a conspirator know they know, the better.
Thoughts?
