This CA POST certified 16-hour course was designed as a refresher or preparatory course for all personnel having evidence collection and documentation responsibilities. The crime scene investigator training course participants will experience the latest in adult learning methods used to facilitate their understanding of how to accurately investigate and document crime scenes while preserving evidence from the initial response to disposition. Learners will apply our Crime Scene Fundamentals to effectively and efficiently document the scene and conduct a better scene investigation with a more careful eye for Evidence Collection and Documentation. Furthermore, through written, oral, and demonstrated assessments, students will leave confident with their abilities to identify items having evidentiary value, deploy appropriate preservation techniques, and to prepare crime scene related reports successfully. Participants have described this course as so essential that it should be a fundamental part of the crime scene investigator education requirements.
