When you think of a rapist, it may been different than what actually took place per this incident.
As mentioned, not enough info to know exactly what happened between the 20 year old and 14 year old, but considering the original sentence, I'm guessing there may of been extenuating circumstances other than a man forcing a girl to have sex with him (which the term rapist implies). It was statutory rape. Not saying the guy didn't know better, but different than a forced sexual encounter.
Also notice that the family wasn't complaining when it was ordered that they should get child support. I would want NOTHING to do with the man, including his money, but apparently for whatever reason, the girls family thought otherwise.
Do LOVE the fact that the family is now trying to get restitution instead of child support.
Be curious to see how this plays out.
