I’m not familiar with the details of this event. But one article I read said three other boys weren’t charged in exchange for testimony. I’m not sure what those charges would have been had they been charged. Apparently the girl was the girl friend of one of the boys charged.
If a Grand Jury gets involved it could lead to some others being implicated.
I've heard it a little differently than you did. I've heard that she broke up with one guy, and he was completely embarrassed, so he and his buddy found a way to get revenge for the break-up. The friend (who is one of the young men found guilty) coaxed her into a date with him for the night of these parties. She was reluctant at first, but then fell for his charms. This was their first "date", so no, they were not boyfriend and girlfriend.

News coverage of the trial showed the defense stating that she “had a crush” on one of the teens. The prosecution said she went along with them, drank until she couldn’t stand up, and the guy she “had a crush on” shared her with his friend.
She made stupid choices. So did the guys. Her stupid choices led to her rape. The guys stupid choices led to jail and a sex offender designation.
