The assistant district attorney will almost certainly speak with you, in fact he is required to keep you informed of the case and its status. He will probably talk with you about what you want to happen to your wife. He is not, however, required to do what you want with the case. Prosecutors can sometimes be very difficult in that they are very willing to go along with a victim who wants the maximum penalty but start thinking independently about the best interests of the State of Kansas when the victim wants the defendant to be cut some slack.
You should try to make you wishes known to the district attorney and also to your wife's lawyer. You also have the right to speak to the judge at the time of sentencing if she is convicted.
This answer is intended to provide general information about the justice system. It does not provide legal advice or create an attorney-client relationship. It does not provide the basis for making decisions about a course of action. Legal advice requires much more communication and information than is possible in this format. Many important considerations and factors need to be investigated and discussed before an attorney could give legal advice about this issue. Before making any decisions about a course of conduct readers are strongly encouraged to contact a lawyer and secure an attorney-client relationship.
