I keep thinking about what happened 2 yrs. ago also, for the 17 yr. old to start planning her escape.
I would suspect she was still getting accosted by her father even if he was only charged with one sexual charge.
I think she started defending herself and fought back so he actually had only successfully made sexual contact one time. She thwarted his attempts until he moved on to try another sibling or he gave up. My guess is he moved on
to one of the weaker siblings and they're not strong enough emotionally or physically to speak of it yet.
In my personal experience (physical abuse only, not sexual) my father continued his cruel punishment towards me
until I was somewhere around 14, 15, or 16, can't recall my age. I finally had had enough and fought back to defend myself against him. He was a big strapping, strong man. But I still fought back with all I had. And I told him he was
never going to beat on me again. He believed me, I guess, because it did stop him as I recall. But I had already told him, while he was beating up a brother, that I was going to call the police if he didn't stop. He stopped. (Coward)
I'm sure that when the police showed up that Sunday morning, those monster parents knew exactly which child had
escaped and turned them in. That was not the first time that she exhibited courage and bravery, it was just the most
important act and most successful at what she intended. Stop the cruelty.
So I believe there was some gruesome attempts at abuse towards the 17 yr. old in 2015 or around there.
