In the way this case was worded, I think there may be more to the story.
The girl said that she was “molested”, not raped, and the boys were apparently charged with “sexual abuse”, for which Kentucky has three different charges, first, second and third degree, not rape.

Sexual abuse in the first degree is a Class D felony.
(At least one (1) but not more than five (5) years.)
Sexual abuse in the second degree is a Class A misdemeanor.
(Between ninety (90) days and twelve months.)
Sexual abuse in the third degree is a Class B misdemeanor.
(Maximum of less than ninety (90) days.)
This is what she tweeted, which sounds like she was raped:
“Afterwards Miss Dietrich tweeted, ‘They said I can’t talk about it or I’ll be locked up... Protect rapist is more important than getting justice for the victim in Louisville.’
