Investigating Homicides

There are nearly as many different ways to approach and investigate a crime scene as there are cops in line at coffee shops. But there are things that should be done at all murder scenes by homicide investigators. For example …

Homicide investigators should:

1. Document air temperature at the scene (ambient air).

2. Document body temperature (if medical examiner is not on scene, document description – cold, warm, frozen, etc.). Detectives do not insert thermometers … well, anywhere. And definitely not THERE!

3. Document livor mortis (lividity). Was livor mortis present, and at what stage? Was it fixed? Was body position consistent with the stage of livor mortis?

4. Document rigor mortis. What stage of rigor? Was the rigor consistent with the crime scene?

5. Document degree of decomposition – skeletonization, putrefaction, mummification, etc.

6. Document animal activity – was the body altered by animals?

7. Photograph the body exactly as it was found. The ground beneath the body should be photographed once the body has been removed.

8. Document victim’s physical characteristics (description of the body, including scars, marks, tattoos, clothing, jewelry, and obvious wounds).

9. Make note of the type of on-scene emergency medical care, or the lack of treatment. The names of everyone at the scene should also be recorded.

10. Document presence of body fluids and where they’re found (mouth, nose, beneath the body, etc.). Also note if there’s no indication of body fluids.

11. Bag the victim’s hands (and bare feet) in clean, unused paper bags.

12. Collect, or arrange for, the collection of trace and other evidence.

13. Determine the need for alternate light sources and other specialized equipment.

14. Photograph the victim’s face for future identification purposes (remember, most present-day identifications are done via photograph or video).

15. Make note of the presence of insects. Photograph and collect samples of each.

17. Supervise the placement of the body into a body bag, and install the proper seal/securing.

18. Ensure the proper removal and transportation of the body.

19. Who, What, Where, How, and When – Who discovered the body? Who was present when the body was discovered? Where was the body discovered? How was the victim killed? When was the body discovered? Who witnessed the murder? Etc. Document all, no matter how insignificant it sounds at the time.

20. Document EMS records/activity. Obtain a copy of the EMS call sheet/report, if possible.

21. Document witness statements – What they observed, the victim’s actions prior to death, killer’s description, etc.

22. Note medical examiner’s comments.

He's dead!23. Obtain witness statements and contact information.

24. Document the names and contact information of everyone present at the scene (officers, EMS, medical examiner, witnesses, etc.).

25. Be certain that all evidence has been recovered before releasing the scene.
