I don't doubt for a moment that darling Lucas was sick with the stomach bug, but I will eat my beloved Red Sox hat with gravy on top, if that is the reason why he passed away. If this was the case, a simple phone call to 911 would absolve EG of guilt right away, and a preliminary autopsy would show the COD from dehydration from the flu. Many children and adults have passed away all across the country this year from the flu, no one would doubt this at all, God rest their souls. If she had nothing to hide, she would have just called for help and the panic would be evident of her sorrow and upset over finding him deceased.
BBM: For some reason I entirely doubt that he was sick with a 'stomach bug' for that length of time. My suspicious mind would be more likely to believe that he was suffering from injuries...perhaps internal, from abuse....and that was causing his stomach pain. And/or...his nutrition was likely not to par. That's all speculation of course, but is a theory that I would believe.
