Sadly, nothing that was done that would justify a criminal investigation.  The owners of a business are entitled to take the money and run if they want to.  It kills the business, but that is what predatory investors do.  They never learned -- or have too short a time horizon to care about -- the story of the goose and the golden eggs.

A successful company is built by people who see a need and a means of meeting that need.  If they are right, they make money, but that profit is a byproduct.  If the company then falls into the hands of people whose only vision is making as much money as they can, as fast as they can -- whether it is the descents of the founders or a rapacious hedge fund -- the world will lose any reason to deal with it and it will fail.
