Parents lock teen in room for 4 years, then kick him out on 18th birthday.

I feel like this is a gender issue; the two sisters were raised normally (Presumably. Barring that, they were raised, period.) while only the male child was locked up.

Can't wait to hear the explanation for this.

The article says the man is his stepfather, I'm guessing the poor boy became the unfavourite when his mother remarried.
