Mansion owners leave - squatter moves in and starts selling off their artwork

Squatter Sells Off Artwork

How does something like this happen?
The original owners were negligent in leaving their possessions (which included works of art) in an abandoned home for years.
Why didn't the bank repossess the property, including the contents?
The squatter had no legal rights to the paintings and so he was charged.
So many unanswered questions.

How strange.

There are lots of fiction writers at BellaOnline. It sounds like it would be the basis for a novel. And plenty of choices of genre.
