here's a synopsis of the case :

The main witness Michael Kleburg's affadavit said that the girl knowingly went into the bathroom where she knew Mark Chmura was changing clothes, despite Kleburg telling her not to. She just looked over her shoulder at him and smiled. After she came out, Kleburg told her she better not have done anything. She swore an oath she hadn't.

The prosecutor threatened Kleburg with an underage drinking charge if he didn't change his testimony. He altered an affadavit, but later disavowed it.

Another female witness also gave exonerating evidence that led to Chmura's acquittal.

Pretty interesting case. Evidently the accused 17 year old girl used a lot of cusswords on the stand.
