To determine whether your testimony will be needed, you should call the LaSalle County State's Attorney's Office at 815-434-8340 and speak to either the prosecutor or the victim-witness coordinator assigned to the case or courtroom. When you call, have the subpoena because it contains the defendant's name, case number, and courtroom. and other important information. If you are needed to testify, the State's Attorney's Office will work with you as best possible to keep to a minimum your time away from work, school, or other obligations. If you receive a subpoena and do not make direct contact with the prosecutor or assigned coordinator, then you must appear at the date and time the subpoena indicates.
