Yes, this a famous Dutch painter Carel Willink, the old guy hunted for a young girl (at that time je waant famous and in debt), first she was his model, next she turned into a living portrait. He even made her personal makeup which could remain for many days.

He dumped her and she died a mysterious death. The killer never been caught. They simply did not solve the murder and let it be. So Mathilda turned into a cold case.
