1. Ensure public safety and control access to the area.
When responding to a death or homicide, it is essential to first ensure public safety and control access to the area for investigative purposes. This includes making sure that any potential hazards such as hazardous material are identified and contained in order to protect both responders and any bystanders from harm. It may also include setting up security measures such as barriers or checkpoints to limit who can enter the area.
2. Record all observations at the scene.
Responders should take notes on everything they see at the scene, no matter how insignificant it may seem. This includes not only seeing any evidence present but also a description of the environment and conditions surrounding the death (e.g., lighting, temperature). It is important to document every detail as accurately as possible in order to create an accurate picture of what happened before, during, and after the death occurred.
3. Document date, time, location & weather conditions.
When responding to a homicide scene, responders must make sure to document pertinent information such as date, time, location, and weather conditions. This information can help investigators determine when and where the victim was last seen alive as well as any possible environmental factors that may have led to their death (e.g., extreme temperatures).
4. Identify evidence that needs to be preserved (e.g., weapons, drug paraphernalia).
Responders must be aware of any items present at the scene that could potentially provide vital clues or evidence in the investigation. This includes items such as weapons or drug paraphernalia which may need to be collected and preserved in order to be used as evidence in a court of law. It is important to take special care when collecting these items so they can remain intact for further analysis if necessary.
5. Collect biological samples for laboratory analysis.
Responders must also collect any potential biological evidence from the scene in order to analyze it further. This includes collecting blood and tissue samples as well as hair, fiber, or other debris that could potentially provide useful insights into what happened before, during, and after the death occurred. It is important to carefully collect these items so they can remain intact for further testing if needed.
6. Take photographs as soon as practicable after arriving on scene.
Photographs are an essential tool for investigators responding to a homicide scene. Responders should take photos of the crime scene immediately upon arrival in order to capture any details or evidence present at the time of their visit that may not be present later on. Photos should be taken from multiple angles and distances in order to create an accurate record of the scene for future reference.
7. Maintain an adequate chain of custody for all evidence collected.
It is essential that responders maintain a clear chain of custody for any evidence they collect at a homicide scene in order to ensure its integrity and validity as it makes its way through the court system. This includes documenting who handled the evidence, when it was collected, and where it was stored during its journey from the crime scene to being presented in court.
8. Carefully document any changes in the environment such as movement or alteration of objects before collecting them as evidence.
Investigators must take special care to document any changes in the environment while they are on scene. This means noting if any objects have been moved or altered before collecting them as evidence, since this can affect their validity and usefulness in court. Taking photos of these changes is also helpful in order to better document the crime scene and its contents for future reference.
9. Document the position and condition of deceased’s body (if applicable).
If there is a deceased body present at the crime scene, responders must take special care to document its position and condition. This includes noting any distinguishing features of the corpse, as well as any clothing they were wearing that may provide clues into what happened or who was involved. It is important to record this information accurately so it can be referenced back later on if needed.
10. Securely store physical evidence collected from death scenes until presented in court or disposed of according to policy/legal requirements.
Once evidence is collected from a homicide scene, it must be securely stored until it can be presented in court or disposed of according to policy/legal requirements. This includes ensuring that the evidence is kept in a secure location and maintaining an adequate chain of custody for any items handled during its storage period. Strict adherence to these protocols will help ensure that the evidence remains valid and accurate when presented in court.
