FWIW. The house being broken into after it was already reported that he was missing
might not be related. Criminals often use information from local newspapers to determine if a home ripe for the picking. Like breaking into a home because they saw that a person recently died and the relatives will be attending the funeral.
It seems like a fairly prominent family. The late husband was a district judge, she is a business woman that owns rental properties. The break-in might have just been a crime of opportunity.
Friends of the family have set up a Facebook page, Help Find Beverly Giannonatti & Greg Giannonatti:
