A child lost in a sea of crap

OK... so Grandma & Grandpa Anthony want immunity now? What the hell? Suddenly they don't want to incriminate themselves? It seems strange to me the reaction they are having, perhaps it's just the move of a paranoid attorney but it makes them sound.... for lack of a better word... involved, doesn't it? 

Of course there is also the fact the tip was called in so many times by the same guy, that can be explained but still sounds fishy. 

The BIG one, the one that smells like week old fishy cheese, now the defense has video of the area before the body was found????? Did they video all the areas surrounding the grandparents home or did they just do this one?  

To many unawnsered questions! Not enough facts floating around yet, the truth is one of those cloudy things, hard to make out, looks like something different to everyone, and damn hard to nail down.
