Please know I'm trying understand that you think maybe the simplest way to look at this is that Dia must have gone for a walk and had an accident, and has not been found yet? Please, there is no "drama", there is only an unexplained missing woman, and now an ongoing battle over her estate. It seems you're disregarding that LE, initially, and probably still does, consider Dia's case a homicide. It's not inconceivable that some evidence was disregarded, missed, not made public. There's all kinds of things to still consider. MOO, there's plenty in this case that seems suspicious and undiscovered yet. MOO, someone could've hired a hit man. She may have been abducted, she may have been killed by someone close to her. There may be someone with a motive we haven't even figured out yet. It's possible she was taken to another location, county, or state and her remains hidden. This is just my own opinion though, and please do not take offense that I disagree with some of your theories.
