So many theories my head is spinning.:crazy: Alot of great point sleuthers.
This is my theory and JMO. Some things that BD has said in her interviews, I'm going with her PC outside her house, she went into more detail on certain issues. This info can be very telling. I said before that I believe whatever happened to HD, happened at the hands of BD. I think BD and HD got into an argument which turned into a physical one and this was BD's reason for going into detail on;
1. There were no blow outs, arguements...Everybody got pretty much what they asked for for Christmas. Could it be HD was upset because DD got an xbox and all she got was a dumb tv? (Just thinking/talking like a kid). An argument/physical fight happened? DD supposidly left around 9/10pm, and guessed HD would be playing a couple more hours. Maybe after DD left, BD told her to shut the xbox off and go to bed, and HD threw a tempertantrum resulting is the two of them becoming physical.
2. BD in her hurried plea to HD in PC. I want to see and touch your beautiful face and wishing you were back in my livingroom. during PC and she almost breaks down because I think she is feeling guilty for possibly slapping or punching HD in the face. OR pushed her against the glass door (in the livingroom) and HD's face got messed up, (BD's mention of her beautiful face)
3.BD talks about HD sleeping on the couch usually, but that night, and the next morning she mentions HD was in her bed. Again a fight may have broke out or continued because BD wanted HD to go to bed, but HD insisted on staying up and/or sleeping on the couch. BD may have said, "you got a tv for Christmas, in your room now go". More escalation.
4.Then BD goes into detail about DD coming home and knocking, eventually letting himself in through broken window, claiming HD broke it. During HD and BD's fight, HD threatened to leave and go to her dads and as she was trying to exit the house, the window broke, BD pushed her into it. I cannot see someone not repairing or securely covering a broken window. Especially in that neighbourhood kwim.
5.Then BD tells about seeing HD in he bed the next morning saying she was pacified and she felt good. In reality BD did not feel pacified and good, just the opposite when she found HD had passed away in the night. Could it be after the fight the night before HD suffered some type of head trauma from BD, went to bed and when BD checked on her in the morning.
Then I feel this is where SA comes into the picture. He may have gotten involved in the physical confrontation. I feel SA is the one who disposed of HD. He put her into the vehicle, took BD to work, he went to work and left ten minutes later, leaving his coverall there because they may have contained HD's DNA, or turned them in just to make it look good. He left work and disposed of HD's body. First he went to granny's place to get something, (shovel, chainsaw...), then onto his mom's to create his alibi. BD said SA knew he was at his mom's before 8am, because she was still home, she hadn't left for work yet. Once his mom left for work, he had many hours to get rid of HD.
Therefore they are both guilty. BD for killing HD and SA for disposal and cleaning/covering up.
I believe SA and BD have sexually, sick, warps, strange, bizarre, minds, especially SA, but I do not feel HD was included in their fantasies. I think it is just coincidental that this sexual stuff just adds to the drama of the case, but I do not think HD was a victim that way. It seems to me, BD had three "kids" in that house, one being SA. I would not be surprised if SA had sexual thoughts of HD or liked to tease, flirt and spy on her. I just cannot fathom a mother allowing her Mr. Awesomeness to have sexual relationships with her little girl. It happens, but I don't think so in this case. And I believe if HD would have been found on any of those digital devices, CP, someone or would be in jail. ASAP JMHO. I have more to say but you're probably fall asleep reading this lol.:seeya:
