Easy to debunk. Just find the wife and kids. Are you sure they are actually missing?
You would think the media would be trying to get some quotes from the family, so far I have seen none.
Looks like they moved on their own. This pilot would be my main suspect.
I wondered the same thing when I first heard the family moved out the day before the flight. Where do they say the husband/Dad went? But there is nothing I have found so far that indicates that anyone has seen or spoken to the family, only that the house was searched.
I have heard nada about where they went. Has anyone? The lack of this news is odd. I give this new option some cred.
Here is a YouTube tribute video posted by his niece or nephew but not his wife or one of his three kids:

At the end of the video he is referred to as "Uncle Ari".
