Just to let you know, we are not talking about a dog failing to hit on pot, we are talking about dogs that "did" hit on both the appartment and vehicle, that is as close to 100% as you can get that a dead body was at these two places.
Now, that does not meak it was this girl, but it does mean there was a dead body in both places, a thing that looks very bad for these people.
As I said before, these are two very well educated people and as doctors, they would know all about body boyancy for disposal, the best way to be sure is to simple vent the body, cut every large section and muscle group, that is assuming a water disposal, there are many ways of disposing a body, again something two well trained doctors would understand.
To reply to Jhony about my leaving kids alone comment:
Would you leave your small kids all alone in a motel room in a strange Country?
I do not know even one parent that would do such a thing. I have three kids and am a school volunteer who helps at field trips and such. I do headcounts every few minutes and am working my eyes over the kids at all times and almost have a cow if there is even a second I cannot account for every child.
Good parents would never do what these parents did, that is why they should face child endangerment charges at the least in my view.
And yes, it is possible they killed this girl by accident, I even believe that is what happened but they had lives, careers and social status to protect, if it was discovered that they medicated their children so they could go out and have fun unhindered by their kids and caused one of their deaths, that would ruin them.
I call that a powerful motive for hiding the body.
