I'll play devils "avocado ".
They had sex at age 12 and 18 maybe 19. Definitely statutory rape . But they may have had a relationship. It was also 9 years ago ? Who knows what relationship mom dad and kid have had in that time . They were probably still in each other's lives .
The fact they share custody implies the kid knows the dad and he's not some stranger.
The prosecutor really blew it back when he was charged .
From what I read, she was 12 and was taken against her wishes and raped. Apparently, there was no relationship.
But that's according to her, and her account is clearly biased.
