In all actuality no one here at WS has 'dragged ' HH into this.
She is nearly an adult and she lived at that house.
And she was stated in the AA as "Not cooperating" with LE.
That speaks volumes.
There's more I can post but will add later as real life is calling.
I'll refer commenters back to
@GordianKnots 's valuable post concerning the red line that has most definitely been crossed.
Again, no one pulled HH into this investigation.
If LE said she was cooperating there'd be less speculation, and we don't know if anything has changed with her refusal to assist LE or --way before TS' arrest for his murder-- not helping to look for a supposedly lost and frightened 11 year old.
Gannon --while he was still 'missing' -- should have been of more concern than a mother's lies and even a daughter's sympathy for TS.
So that's about the state of things at this point.
