An inquest is an investigation into the cause and circumstances of a death. Laws vary from state to state and the circumstances under which an inquest may be required are usually specified in a state’s statutes.

For example, if a person dies in a county with a medical examiner, the medical examiner (or authorized deputy) may be required to conduct an inquest under the these and other circumstances:

• when a person dies within 24 hours after being admitted to a hospital or institution, or dies in prison or jail;

• when a person is killed, or dies from an unnatural cause of death (unless executed by the state for a crime), or dies without one or more good witnesses;

• when the body or a body part of a person is found, and the cause or circumstances of death are unknown;

• when the circumstances of the death of any person lead to suspicion the person died by unlawful means;

• when any person commits suicide, or the circumstances of the person's death lead to suspicion the person committed suicide;

• when a person dies without having been attended by a duly licensed and practicing physician, and the local health officer or registrar required to report the cause of death does not know the cause of death;

• when the person is a child and the death is required to be reported by law; and

• when a person dies who has been attended immediately preceding death by a duly licensed and practicing physician or physicians, and such physician or physicians are not certain as to the cause of death and are unable to certify with certainty the cause of death.

In Kansas, an inquest is a formal judicial inquiry to determine the cause and circumstances of a death. The Kansas statutes outline specific situations where an inquest is necessary, typically involving the county's medical examiner or a designated deputy. These situations include deaths occurring within 24 hours of hospital admission, in prison or jail, from unnatural causes, without reliable witnesses, or under unknown circumstances. An inquest is also mandated for deaths that raise suspicions of unlawful means, suspected suicides, unattended deaths where the cause is unknown to the reporting health officer, child deaths that are legally required to be reported, and when a physician cannot certify the cause of death with certainty. The medical examiner has the authority to decide when an inquest is warranted and to conduct the investigation accordingly. The purpose of the inquest is to establish the cause of death, which may have legal implications, particularly if the death resulted from criminal activity or negligence.
