Only part of the story as usual. They quit counting the money when it got to 45K and decided they needed to find the family of the former owner.
Also not mentioned was the family wasn't overly surprised because they found something like 15k stashed in his stuff when they were cleaning out the house.
That part bothers me somewhat. If I was cleaning out say my dads house and found cash squirreled away you can bet your ass I'm looking everywhere in that house before I sell it. It's only prudent.
AND, maybe some real estate folks here can answer this, don't you own everything in the house once you close on it, good or bad?
