A defense investigator fulfills one of the most important roles on the defense team. The investigator’s job is to verify and validate all that has been done by the investigating police department. With that in mind, the investigator has to have accumulated training or experience which would allow him or her to recognize where any errors or omissions have occurred or to indicate that all proper procedures were adhered to during the investigation.
Know what the standards are! The investigator has to talk to each witness and to review and verify all evidence, physical, verbal, video, etc., that will be used by the prosecution. A.J. Keirn has valuable experience in investigation support.
