One fact sticks out to me that a parent who accidentally left their child in a vehicle wouldn't do...claim like the father did that his child (in a state of rigor mortis) was choking moments earlier. I can't fathom a parent who was accidentally forgotten their child in a hot vehicle making such a statement to cover up the facts.

"When he pulled in and people started asking him what had happened, he said that the baby had just started choking.
'But the baby didn't look like it had been choking, it looked like it had been sweating, like it had been in a swimming pool, his hair was all wet."

"In a few -- in a matter of a few minutes of arriving at work, you`re telling me that this man completely forgot this child was in the backseat?
And witness testimony stating upon arrival and finding that child, he was saying it was choking. Well, guess what? Somebody also said rigor mortis
had set in. The child would not have been choking if it had been deceased for a matter of hours."
