My poor parents?!!!! 
I didn't post my life story because it's not relevant to the OP. My point is, that at 16 there's not a lot a parent can do.
Yeah, they could have called SS. Who would have chatted to a grade A student enrolled already at college in her new town doing A levels and with a part time job lined up to support that. And done nothing.
Not quite sure why my "poor parents" deserve an apology when me calmly announcing my plans to move out age 16, during the summer, result in a beating (not the first) house arrest for a week and then my father nearly crashing the car trying to beat me again before pulling over an hour before my first GCSE and telling me to just get out, go if I was going.
I sent postcard olive branches for 3 years without hearing anything. After 10 years it was me who engineered a meeting. Hosted them in my home. Since then, they have stormed out and cut me off again twice and now I don't bother with them at all.
I have 3 siblings who are all very close to my parents, all 3 of whom I am also close to and all 3 are "we love them but we don't know why you are the black sheep and this is unfair".
So no, I fucking well will not be apologising to them!
I am generous of spirit - I never once asked them for an apology when I let them back into my life.
Including my wedding, at which my mother got drunk and complained to anyone who would listen that she didn't have a "role" as MOTB and no-one knew who she was. It was an informal wedding with no top table or speeches and she was given a front row seat in the ceremony room that had limited numbers.
So no - I have not apologised to my "poor parents"
