It probably was not pursued because she just wanted to use the rape as an excuse for her parents not to condemn her for going with those three voluntarily.
Exactly!!
Maybe she needed an excuse for her new fiance' for not being a virgin at 17. When she told him about it, he forced her to file a report.
Good theory. That ultimately turned out to be the real story behind the Tawana Brawley fraud, IIRC.
Tawana had disappeared for a couple of days with her boyfriend, and feared the wrath of her parents. So she came up with her rape tale.
At least Crystal didn't blame her first "gang rape" on eeeeevil white men.
