Here's something strange about the "change of address."
The husband said:
He said last Wednesday he received a notice from the Post Office indicating she had entered a change of address form dated April 30.

Okay, this is pretty obvious, but wouldn't this "notification" tell the new address of Mrs. Palmgren? Which means he would know where to find her, right? :waitasec: Unless she was going to use a post office box, in which case they would still know the location of the post office where the box was located.
And I remember when my daughter moved away for Law School but before she had her internet hooked up, I had to change her address for her. So I did it all online, simple, and took five minutes.
My point is that beyond your old address and your new address, I don't recall that they ask for any identification beyond an email address. So it seems to me that anyone could have done that change of address and sent the notification to Mr. Palmgren's email or even to his mailing address.
