Expert Witness Testimony The trial is the final stage of the case, when all of the evidence is compiled to assist the prosecutor with assigning charges and preparing for trial. If the reports are not written properly, they cannot be used at trial. At the trial stage, you move from a crime scene technician to an expert witness who must provide testimony in a courtroom in front of a judge and jury. In court, you will be asked a series of questions in regard to your name and background in the field you are testifying to. The series of questions pertaining to educational level, years in the field, amount of times previously testified, and total number of identifications made in the past. The answers to these questions will determine if you should be considered an expert witness. Answer the following questions, which will more than likely be asked by the prosecutor or defense to qualify you as an expert witness. Please state your full name for the court and spell your last name: Where are you currently enrolled as a student and in what program? Briefly explain your experience in processing evidence and crime scenes: Briefly explain the crime scene sketch used for this case. Briefly describe the photographs taken for this case. Explain the fingerprint evidence recovered at the scene and the results of the examination.
