A plausible scenario is this: After their overmedicated child succumbed, the panicked parents decided they could not bear the cost of being held responsible (loss of jobs, criminal penalties, etc.) They decided their only reasonable option was to dispose of the body, but could not immediately because of all the attention paid to them. Some time later they rented the car and disposed of their child with as much dignity as could be afforded under the circumstances.

that was also my first reaction, however, how much easier would it have been, if the child had been administered a sedative, to maintain that the pills were left where she could access them? In other words, the child took them herself? And seek immediate medical attention by calling an ambulance?

But all this still does not explain the apparent presence of blood.

it certainly doesn't.

I am always reminded of the Lindy Chamberlain case in Australia, the mother went to jail for years before she was exonerated. An 'expert' provided evidence that there was blood found in their vehicle. It turned out to be rust-proofing residue.

If they gave the other children pills too, it would be a bit difficult to claim they ALL got into the pills.

And I don’t know many almost four year olds who would eat pills, anyway.
