Law Enforcement Training


The Evidence Technician Training Course is an 80-hour course. Excellent teaching and student participation is guaranteed by limiting the class size to nine students. Officers are instructed by Coroner and Crime Laboratory personnel and are taught collection and packaging in all areas of evidence processing. A mock crime scene is used for teaching crime scene sketching and processing skills. At the end of the course, each officer is given a written examination. Upon successful completion of the course, the officer becomes a Miami Valley Regional Crime Laboratory-trained Evidence Technician.
