This is my first post... As I have lurked since sweet Caylee
I have known this family since before the house fire, although i had never met todd. I no longer have a close relationship with any of them as most of the family has left the area- as have I.
I agree with most of you that this is not looking good for Todd or Katrina, but I have seen innocent husbands get sent to jail for murders they did not commit (Bradenton fl murder of Sherry Brannon and daughters).
Although, his past looks bad, it does not necessarily mean he murdered his wife. Maybe more likely, but definitely isn't a given. I do not believe you will see Todd's parents support him, as I understand it, they are estranged and live out of state.
As for other scenarios- there are RSO close to where her car was found. We have all seen crazy outcomes this month. I hope for the families sake and Todd's daughters that this turns out to be a stalker or stranger.
