If he was a resident of Florida, your son will have to file a petition to probate his estate there. As part of opening the estate, he can apply to be appointed as the personal representative of the estate.
Once he is given this court-ordered title, your son can collect your father's property - including whatever is at his house - life insurance money, etc.
The first thing you should do is contact an estate attorney in the county of his residence for help with getting this process started.
