Ok...so you've spoken with these "two other girls" such that you know what they know and what they recall all these years after the fact? Are they willing to testify voluntarily or are they still living in the area such that they're subject to being compelled by supboena to testify?
Bottom line: Your wife is free to contact the police and/or the local prosecutor and report what happened. Likewise, she's free to consult with a local attorney. If she wants to sue the person she claims raped her (does she even know where he is?), she (and you) will probably have to pay a lawyer a rather hefty retainer because I doubt any lawyer is going to take a case like this on contingency). As I said initially, no one here is in any position to know how the police or a prosecutor might react, much less how a criminal or civil case might turn out. All we can do is point out the obvious problems with a case such as you have described.
