Please discuss the responsibilities of the first officer at a crime scene, specifically a murder scene where the suspect has departed. Discuss the methods an officer would use to secure a crime scene and why they would choose a specific method in a specific situation. Compare and contrast hypothetical crime scenes taking place in a room, a mall, or a bank, etc. Lastly, discuss what is the relationship in between responding police officers and the investigators. How does that tradeoff, exchange of information or release of information occur and why is it important.
