You need an attorney. Your wife cannot force the District Attorney to drop the charges. If they have enough evidence to move forward (which her statements give them) then the D.A. will not just drop the charges. The case needs to be set for trial.
Now, if your wife is not compelled to appear in court then the case may be dismissed as there is probably insufficient evidence to proceed without her testimony. If she is subpoenaed to testify then you may still be able to obtain an acquittal. However, you cannot do this by yourself. You need to hire an attorney.
