I don't agree, Evan's Mom. We don't know what happened yet. Suppose Maxie, GS and Rebecca (along with the dog,) were all together and RN went to answer the phone and it was JS. At that moment would JS blame RN, or would he think, 'if I had only called later RN could have been supervising them.' There are many scenarios that could have taken place. Besides which, who watches their six year old every second. Yes, you stay in the same area where they are, but you can't be there constantly.
Also, RN was know to be a nice, sweet, religious woman. There is no way I believe she would do this, especially naked (I believe it would be shameful to her.) And, if she felt she was in some way truly responsible, I believe she was the type of woman who would write a note, not just to JS, but to DS and the rest of the family as well.
All that being said, I predict this will be another dead end case. JS has plenty of money, already has the best PR firm around (either through his company or personally, it doesn't matter,) and he and his shareholders have too much to lose.
To me it screams murder. I'm not sure who yet, and there are alot of suspects, but I'm thinking 1. JS, 2, AS, 3. DS, in that order. We need to know when AS told his landlord he was going back to his tug, did he go to the hospital, did he attend either funeral, and what actual help he was to his brother?
