Your letter doesn't go to their insurance company. (State Farm wasn't it?) It goes to the Texas Dept of Ins., in Austin, I guess. I didn't search for an address. I'm sure they can find it in their computer with the information you reference without a policy or claim #.
One thing I forgot: when you write any registered letter, after your reference lines
(Re: Houston Arson Division Ref #:________
Date of Incident:_________
Address:_________
Named Insured:__________
Insurance Co.:____________)
and a couple of lines above Dear _______, type in "Registered - Return Receipt Requested." That way, if you *do* have to forward copies of your unanswered letters in the future, the atty gen's office will see that you sent a letter that had to be *signed* for, and it was *ignored*. Letters that have to be signed for usually get answered, whereas letters which don't have to be signed for can "get lost in the mail." *Registered* letters don't usually get ignored.
Omit the "insurance company and named insured" in letters to the chief and arson investigators and replace it with "Name of Deceased:__________
I *sincerely* hope something comes of if for you, Cob; you've *earned* it...
