Course Objective

In this course of instruction, a multifaceted investigative approach will be provided to establish the investigative framework from which a lead homicide detective will be able to conduct an all-encompassing and most intrusive investigation into the murder of a human being. In order to accomplish this, multiple facets of a homicide investigation will be explored that are foundational to identifying, understanding and holding those persons criminally culpable for the death of another. From the initial response, applying behavioral and forensic examinations at the crime scene, prioritization of investigative measures, interview strategies and the necessary collaboration with a prosecutor in preparation for trail are covered. Additionally, the course will engage the participants in an interactive classroom setting in which actual cases are reviewed and analyzed to augment the lecture and teaching points brought forth. The participants will then put their newly acquired knowledge to the test through the application of course practicums in order to demonstrate their acquired proficiency.
