The older 1 managed to get via it and reside a reasonably regular lifetime, but the young sister was so warped by the abuse that she tried out to molest a small female and then killed her when she freaked out. But later on they come across that she had a "stillbirth" a few yrs prior, and Benson confronts her with that - and the woman blurts out that her father was also THAT baby's father, and she'd really killed that baby herself.
