The Role of the Medical Examiner and Coroner
When a death is unexpected, suspicious, or occurs without a doctor present, the medical examiner or coroner becomes involved. Here's what that means and what to expect.
Most families don't know what a medical examiner or coroner actually does until their involvement is required. When it is required, families often feel confused, anxious, and uncertain about the process and what it means for their loved one. This guide explains when and why these officials become involved, what they do, and what families can expect.
Medical Examiner vs. Coroner: What's the Difference?
These terms are sometimes used interchangeably but refer to different offices with different qualifications:
Medical Examiner (ME)
A medical examiner is a physician — typically a forensic pathologist — who is appointed, not elected. Medical examiners have medical training to investigate cause and manner of death. Most large cities and urban counties use a medical examiner system. The Office of the Chief Medical Examiner is typically a government agency staffed by physicians and forensic specialists.
Coroner
A coroner is an elected official in many counties who is not required to have a medical degree. Their role is primarily administrative — certifying deaths, managing investigations, and in some jurisdictions, making inquest determinations. In counties with coroners rather than MEs, forensic pathologists may be contracted to perform autopsies when needed. Some states use a combined coroner/medical examiner system.
For families, the distinction usually doesn't matter much in practice — both offices perform similar functions in investigating deaths.
When Is a Medical Examiner or Coroner Involved?
Not all deaths involve the ME or coroner. They typically become involved when:
- The death is sudden or unexpected — a person with no apparent terminal illness who dies suddenly
- The death is unattended — no physician was present or treating the person in a manner that would allow them to certify the cause of death
- The manner of death is potentially unnatural — accident, homicide, suicide, or undetermined
- The death occurred within 24 hours of hospital admission — this triggers a review in many jurisdictions
- There are suspicious circumstances
- The identity of the deceased is unknown
- Public health considerations — deaths from certain communicable diseases
Dying of a clearly expected illness, under a physician's care, with a valid DNR and hospice involvement generally does not involve the ME or coroner — the treating physician certifies the death directly.
What the Medical Examiner or Coroner Does
Scene investigation
The ME or coroner's office may send an investigator to the scene of the death to gather information about the circumstances. They will examine the body, the environment, and interview witnesses. The body will be transported to the ME/coroner's facility for further examination.
External examination
In many cases, especially for deaths that appear to be from natural causes, an external examination of the body is sufficient to determine cause of death. An autopsy may not be required.
Autopsy
An autopsy is a surgical examination of the body to determine cause of death. The ME/coroner's office orders autopsies when the cause of death cannot be determined from an external examination, when there are suspicious circumstances, or as required by law in certain categories of death. Families cannot typically refuse an ME/coroner-ordered autopsy (it is a legal investigation). However, families can sometimes provide information about the deceased's medical history that may affect whether an autopsy is deemed necessary.
Toxicology
Blood and tissue samples are often taken for toxicology testing (testing for drugs, alcohol, and other substances). Results can take weeks to months.
Death certificate certification
The ME or coroner certifies the cause and manner of death on the death certificate. If toxicology is pending, the death certificate may initially list cause of death as "pending investigation." A final certificate is issued once all results are available.
What Families Should Know About the Process
Timeline
The ME/coroner's review adds time to funeral arrangements. For straightforward cases, the body may be released within 24–48 hours. Complex cases involving crime or toxicology may take longer — sometimes several weeks. Funeral arrangements typically cannot be finalized until the body is released.
Personal effects
Clothing and other personal items on the deceased may be retained as evidence in cases under investigation. They may be returned to the family when the investigation concludes.
Communication
The ME/coroner's office is a government agency — they may not communicate proactively with families. You may need to call them directly to get updates. Be patient; these offices are often understaffed and dealing with multiple cases.
Private autopsy
If you disagree with the ME/coroner's findings, or if you want an independent assessment, you can commission a private autopsy from an independent forensic pathologist. This must typically be done after the ME/coroner releases the body. It does not change the official record but can provide additional information or support a legal challenge.
After the Investigation
Once the ME/coroner releases the body, the family can proceed with funeral arrangements normally. The funeral home will coordinate pickup from the ME/coroner's facility. The investigation's findings are contained in a final report, which the family may request a copy of.
