I have donned and adjusted my little tin foil hat so I can share my theory - and remember, I could be totally nuts and hopefully don't get banned for it, but here goes - I think NH was up to something nefarious way back - drugs, firearms, who knows. I think Officer Ellis found out or suspected and had be to taken out of the picture - remember he was not driving his vehicle that night and his canine was not with him, someone had put tree branches in the road to make him stop. Who would have known what vehicle he was driving?? Regarding the Netherlands, I think the daughter saw something at school or after school and confided in her mother. I think her mother called the police on her behalf and said they needed to speak to someone. The person that killed them came to the front door - which they very seldom used. Who is going to come to the front door?? Mom was shot basically in the doorway and the daughter was shot fleeing thru the house. Crystal and her daughters - were they becoming a problem to BH? threatening to leave and take the little boy? After all, BH was only interested in the son - not the other kids that were not his. NH says - theoretically - no problem bro, i can help you out! Small town, good family - Tommy is yelling long and loud about his daughter and so he has to go as well. someone heard the car leave very shortly after the shot was fired, so sounds like two people in the car. Disclaimer - most of my thought processes come from the miniseries about Crystal and could be completely erroneous. But in my opinion, NH has been in this up to his eyeballs since day one. Apologies in advance if I stepped on anyone's toes.
