Some wild speculation of mine. Just think about it.
(1) Dad is not babysitting like he should. He comes home from partying with female neighbor. Danielle is not in bed. Dad accidently runs over her pulling into drive.
(2) Mom and guests pull in at 2:30am, same scenario, accidently run into Danielle with car.
In either case, parents panic. Maybe they stash her body in Neighbor's RV.
(3)Neighbor coming home at 10:30pm accidently runs over Danielle, decides to get rid of the evidence.
Like I said, all speculation, but there is more to this than meets the eye.
What 'stairwell' had blood traces ? Basement, upstairs, what ?
Why was Danielle's body partially 'burned' ????
I think the biggest problem with this whole matter is the mystery surrounding the parents and their contradictive answers.
Or was Gary Condit a guest at their party ? (now I am really out there, huh!)
