Somewhere, I heard one of the van Dams say that Danielle was a heavy sleeper and most likely thought it was her father carrying her, instead of the perp. OTOH that the van Dams also said that Danielle "sleep-walked"...
If Danielle sleep walked, was there a gate across the top of the stairs?
Or is this a possible defense to a charge that the van Dams may give her sleep medicene?
Is there evidence in Danielle's medical record that she sleep-walked?
Sleepwalking usually occurs in a partly awakened subject, usually a child. Sleepwalking can be initiated by worry or tension. Sleepwalkers usually don't remember their activities.
Perhaps the noises in the garage awakened young Danielle, and the commonly agreed on explaination given by the van Dams was that she sleepwalked. However, swinging guests concerned for their privacy may have suggested to the van Dams another course of action:
drug your children to protect our activities.
Like I said before, if Weseterfield obtained information that the children, and in particular Danielle, was drugged on party nights,
this would have sent his opportunity meter OFF SCALE,
assuming he was the abductor.
Okay, here are some more thoughts for the open-minded. If Danielle was accidentally killed or not, she could have awakened at some point and started screaming. The killer could have put a pillow or something over her mouth to make her quiet and in the process accidentally suffocated her. This wouldn't show up on autopsy. Maybe Law Enforcement already suspects this? The drugging aspect is certainly a possibility I hadn't thought of. It would explain why her and her brothers did not wake up or scream when the intruder arrived. Another theory is that she knew the intruder well enough not to be afraid to go with him. This part has been bothering me the most of all this.
