What to Do After an Unattended Death in Arizona: A Step-by-Step Guide

First: Take a Breath

If you have just discovered an unattended death, the most important thing to do in the first moments is to not enter the scene beyond what you already have. You do not need to do anything other than leave the room and call for help.

This guide is here for when you are ready to understand what comes next. Everything after that first phone call is something that professionals — law enforcement, medical examiners, and cleanup specialists — handle every day. You do not have to figure this out alone.

Step-by-Step: What to Do After Discovering an Unattended Death in Arizona

1. 1

   Call 911 immediately

   Even if the death is clearly not recent, call 911. Law enforcement must respond to every unattended death. Do not call the funeral home first — they cannot legally take custody of the body until the medical examiner releases it. Calling 911 is the required first step in Arizona.

2. 2

   Do not enter or disturb the scene

   Leave the room or property as you found it. Do not open windows, remove items, or attempt any cleaning. Law enforcement will need to assess the scene in its found condition. Disturbing the scene, even unintentionally, can delay the medical examiner's release of the property.

3. 3

   Wait for law enforcement and the medical examiner

   In Arizona, all unattended or unexpected deaths require an investigation by the county medical examiner. This is not an indication of wrongdoing — it is standard Arizona law for any death without a physician present. The investigation can take anywhere from a few hours to several days depending on circumstances.

4. 4

   Obtain the medical examiner's clearance

   Once the medical examiner has completed their investigation and released the body, you will receive documentation that the scene has been cleared for cleanup. This paperwork is important — keep a copy. The cleanup company will need confirmation that law enforcement has released the property.

5. 5

   Contact your insurance company

   Before cleanup begins, call your homeowners or renters insurance carrier to open a claim. Provide your policy number and a brief description of the situation. Get a claim number. Many policies cover biohazard cleanup — do not assume you are paying out of pocket before checking.

6. 6

   Call a certified biohazard cleanup company

   This is not a job for a general cleaning service or for doing yourself. Unattended death scenes involve bloodborne pathogens, decomposition compounds, and in Arizona's climate, potentially accelerated biological material spread. A certified company like New Light Environmental has the protocols, equipment, and regulatory compliance to handle the cleanup safely and completely.

7. 7

   Allow the cleanup to be completed and receive clearance documentation

   A certified company will clean the scene, test for biological contamination using ATP bioluminescence testing, and provide a written clearance report confirming the property is safe. This documentation is essential for insurance claims, property sale, and your own peace of mind.

8. 8

   Address the estate and legal matters

   If you are a family member, begin the estate process — notifying the Social Security Administration, contacting an estate attorney if needed, and working through probate if applicable. If you are a landlord, this process is separate from your property remediation obligations.

Why Arizona's Climate Makes Professional Cleanup Essential

Arizona presents a specific challenge for unattended death scenes that other states do not face as acutely: heat. Phoenix summer temperatures can reach 115°F or higher, and even air-conditioned homes may have disrupted HVAC systems when found.

At elevated temperatures, decomposition progresses dramatically faster than in cooler climates. This means:

• Biological material may penetrate flooring, subfloor, and structural materials within 24–72 hours at summer temperatures
• Decomposition odor compounds bind to porous materials — drywall, insulation, concrete — requiring professional molecular neutralization, not surface cleaning
• Secondary contamination through HVAC systems is more likely in homes with forced-air systems that were running during the decomposition period
• The cleanup scope — and cost — typically increases the longer a scene remains unaddressed after discovery

This is why Arizona law enforcement and medical examiners routinely recommend immediate professional cleanup as soon as a scene is cleared — not days later.

What If I Am the Landlord?

If the unattended death occurred in a rental property you own, you have specific obligations as an Arizona property owner:

• You are responsible for returning the property to a habitable condition — which requires certified biohazard remediation, not just general cleaning
• Under Arizona's residential landlord-tenant law, you cannot re-rent the unit until it has been properly cleaned and cleared
• Your landlord insurance policy typically covers cleanup costs — call your insurer before paying anything
• You may have disclosure obligations to future tenants and, if selling, to buyers — a written clearance report from a certified company protects you legally
• You are not required to attempt the cleanup yourself, and doing so without proper certification creates liability
