Yes, what all of you said.
There's something else important here, though.
This man "fell in love" with the girl when he thought she was 19 and chose to remain in the relationship after learning she's only twelve. Bad decision. Stupid decision. Immoral decision.
However...
After putting himself in a legally vulnerable position by escalating this to a sexual relationship he put himself at even greater legal risk by calling the police to report that he believes she's been raped in her home.
Whatever the imbalances and wrong-doing in this situation, it's highly possible that he cares what happens to this girl and that she's given him reason to think that she's been the victim of incest in her home.
The parents should be investigated under a very powerful microscope.
I have to process what you said. A 41 yeard old pervert beds a 12 year old girl and he cares about her.
