I watched the interview on 20/20 last night and I've been reading the fallout from it. Specifically the response by Van Der Sloot's attorney.
This is what I think. I think he lied about calling someone to dispose the body. I believe he disposed of it himself. The events around his friend coming over to dispose the body and Joran's walk home apparently don't line up. The phone call from the phone booth couldn't have happened because it doesn't take local calls. I believe that he was on the beach with her and I believe that while she was with him she died and I believe that he did absolutely nothing to help her and I believe he disposed of the body.
And the fact that he did dispose of the body implies to me that he was somehow involved in her death.
One thing is for sure; his attitude regarding the entire episode has been and continues to be absolutely disgusting.
I wonder if his parents continue to feel compelled to unconditionally stand behind him.
