What happened?

I just want to know what happened the night Amanda died. The good bad, and ugly. I can't really express this with other people as I get the "churchy" answers like, "Let go and let God." I don't doubt where she is and I know there are many things I have to let go of; however, those responses come from people who haven't had the burden of having a child go to Heaven before them. I think it is perfectly reasonable for my heart and mind to want the answer to what exactly happened that night almost six months ago. And the kicker is that I KNOW Ryan and Erica know what happened but aren't speaking. What if it was their little boy? It is irrelevant to me that Amanda made a choice to go over there. I know that. I want to know what happened after that. I more than sort of wish I had a way of tracking them down in L.A. or wherever they are now and get these answers. I feel like our rinky dink police force here just said, well she was a willing participant and she is dead, so it doesn't matter what happened. I get that to an extent as perhaps there is no legal reason that they have in front of them to dig deeper, but I'm not law enforcement; I'm a momma who wants to know what happened.
