When you arrive at the scene of a crime, you must follow certain procedures to ensure the admissibility of evidence. For this assignment, you will use a case file of a real crime scene and assume the role of the crime scene investigator. You will create a presentation in which you document your process, present your findings, and provide an evaluation of the scene in a narrated PowerPoint or presentation tool of your choice. 

Choose one of the following cases from your textbook resource:

• "He Hit Her Until She Fell… and That Was Just the Beginning," Brandl, pp. 363–373.
• "A Mutilation Murder," Brandl, p. 670.

Then, create a 5–10 minute presentation in which you:

1. Identify the tools you used to evaluate the crime scene. Provide a rationale for your choices.
2. Outline the steps you took to secure the crime scene.
3. Describe the techniques and procedures you used to process the crime scene, including a list of the evidence collected. Explain the reasons for your procedures.
4. Describe the steps you took to preserve the evidence and provide an explanation for your process.
5. Provide photos of the crime scene.
6. Create a crime scene map that illustrates the crime scene upon arrival.
7. Narrate your presentation to walk the audience through the crime scene.
8. Use at least two quality sources and cite them on a references slide.
