Just replying to my own post. I had a few more thoughts. Lol
I can sort of understand 'panicking' if it was an accident and the perp didn't want to lose their daughter, their other grandchild and perhaps their livliehood. It could almost be categorized as temporary insanity. Having a dead child on your watch would absolutely be traumatizing.
However, that does not excuse the ongoing obscufacting of what happened and where he is.
The fact that the two suspects are the grandparents, the ongoing unaccountability despite their only daughter being destroyed by this is evil. There is no excuse whatsoever for having this go on for nearly 6 months with continued lies.
If it truly was an accident, taking accountability regardless of the consequences would be the right thing to do. And they may even have gotten leniency, we don't know.
Because of all this, I am now leaning towards anger being the motive. The person responsible, by not taking accountability shows selfishness, stubbornness, disregard for their daughter, and obvious disregard for poor sweet Gus.
Anger towards Gus himself or his dad is hard to say without all the facts.
When I said it reminded me of Gannon, the more I think about it, the more I feel this was similar in nature.
