Are Autopsy Reports Public in Missouri? (2026 Guide)

Missouri autopsy and coroner reports are generally open to the public under state law, and a completed report can be obtained with a written request to the county coroner or medical examiner that handled the death. The major restriction is timing: records tied to an open law enforcement investigation can be closed under Missouri's Sunshine Law until that investigation becomes inactive.

Are Autopsy Reports Public in Missouri?

Yes. In Missouri, completed autopsy and medical examiner reports are generally treated as open public records, because the Sunshine Law makes the records of a public governmental body open for inspection and copying unless a specific provision closes them (RSMo 610.011 and 610.023).

The underlying record-keeping duty differs by county type. In the counties that use a medical examiner, RSMo 58.740 requires the medical examiner to keep full and complete indexed records of each death investigated, with the pathologist's report and the detailed findings of the autopsy attached to each case file. In coroner counties, the statutory duty is narrower: RSMo 58.451 requires the coroner to file a copy of the findings in the coroner's office within thirty days of establishing the cause of death.

The practical rule offices apply is simple. Cases that are completed are available when a written request is made. Cases still tied to an open law enforcement investigation can be withheld while that investigation remains active.

That investigation hold is the most important exception, and it runs on the statute rather than on a prosecutor's approval. RSMo 610.100 keeps a law enforcement investigative report closed until the investigation becomes inactive, which the statute defines as the agency deciding to take no further action, the statute of limitations expiring, or the finality of a conviction. RSMo 58.740 does require a medical examiner to promptly deliver copies of records to the county prosecuting attorney where further investigation may be advisable, but that is a referral duty, not a precondition to public release.

Who Performs Autopsies in Missouri?

Missouri runs a county-based death investigation system rather than a single statewide medical examiner. Most of the state's counties are served by an elected coroner, while a small number of larger jurisdictions, such as the City of St. Louis and Greene County, use an appointed medical examiner instead. The basic authority sits in Chapter 58 of the Revised Statutes of Missouri.

The coroner or medical examiner investigates deaths that are sudden, violent, suspicious, accidental, or unexplained, including deaths where no physician was attending. An autopsy is generally discretionary. The coroner may order one when, after viewing the body and inquiring into the cause and manner of death, the official determines a further examination is necessary in the public interest.

Some deaths trigger a mandatory examination. Under Missouri law, a sudden unexplained death of an infant between one week and one year old is to be autopsied by a certified child-death pathologist.

A full autopsy is rarely instant. It usually includes toxicology and laboratory testing, which is why the final written report can take weeks to finish even when the body is released to the family quickly.

Who Can Request a Missouri Autopsy Report?

Both family members and the general public can request a completed Missouri autopsy report, because these are open records once the case is closed. You do not have to be next of kin to ask for a finished report.

What changes by status is access and cost. Immediate family and legal next of kin are the most common requesters, and many offices provide the report to family with little friction. The public can also request a completed report under Missouri's open-records framework.

The line that usually matters is not who you are but whether the case is open. While a law enforcement investigation is active, the related records can stay closed to the general public. Relationship still counts at that stage, though. RSMo 610.100.4 lets a family member within the first degree of consanguinity of a deceased person involved in an incident, or that person's attorney or insurer, make a written request for records closed under that section in order to investigate a civil claim or defense, and the agency then has thirty days to produce the material or ask the circuit court to keep it closed. RSMo 610.100.5 separately lets any person bring an action in circuit court to authorize disclosure of a closed investigative report.

How to Get an Autopsy or Toxicology Report in Missouri

To get a Missouri autopsy or toxicology report, send a written request to the custodian of records at the county coroner or medical examiner office that handled the death. Requests are typically accepted by mail, email, or fax, and some offices take them by phone.

Include the decedent's full name, the date of death, your name and address, and your relationship to the deceased. Asking the right county matters, because the office that performed the autopsy holds the report, not a central state agency.

Fees vary by county. Many offices charge nothing to immediate family members for a copy of the report, while charging others for copying, redaction, and staff research time. Some counties also recover a share of the actual autopsy or toxicology cost, often capped at a set dollar amount for a standard request.

Plan for processing time. Reports are commonly available about 8 to 12 weeks after the autopsy, and some offices cite roughly three months from the date of death. Offices commonly hold a report while a criminal case is open, and many will not release records until any fee is paid.

Autopsy Report vs Death Certificate in Missouri

The autopsy report and the death certificate are two different documents from two different offices. The autopsy report is the coroner or medical examiner's detailed examination, including toxicology findings and the official's conclusions about cause and manner of death.

The death certificate is a vital record issued by the Missouri Bureau of Vital Records. It lists a short cause-of-death line and the manner of death, but it does not contain the full narrative, lab data, or findings that the autopsy report does.

If you need the underlying medical detail, you want the autopsy report from the coroner or medical examiner. If you need a legal record for probate, insurance, or benefits, you usually need a certified death certificate. For the certificate process, see Missouri Death Records.
