Art. 49.25. MEDICAL EXAMINERS
Sec. 6. DEATH INVESTIGATIONS. (a) Any medical examiner, or
his duly authorized deputy, shall be authorized, and it shall be his
duty, to hold inquests with or without a jury within his county, in the
following cases:
1. When a person shall die within twenty-four hours after admission to a hospital or institution or in prison or in jail;
2. When any person is killed; or from any cause dies an
unnatural death, except under sentence of the law; or dies in the
absence of one or more good witnesses;
3. When the body or a body part of a person is found, the cause or circumstances of death are unknown, and:
(A) the person is identified; or
(B) the person is unidentified;
4. When the circumstances of the death of any person are such as
to lead to suspicion that he came to his death by unlawful means;
5. When any person commits suicide, or the circumstances of his
death are such as to lead to suspicion that he committed suicide;
6. 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 under Section 193.005,
Health and Safety Code, does not know the cause of death. When the
local health officer or registrar of vital statistics whose duty it is
to certify the cause of death does not know the cause of death, he shall
so notify the medical examiner of the county in which the death
occurred and request an inquest;
7. When the person is a child who is younger than six years of
age and the death is reported under Chapter 264, Family Code; and
8. When a person dies who has been attended immediately preceding
his 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 as
required by Section 193.004, Health and Safety Code. In case of such
uncertainty the attending physician or physicians, or the superintendent
or general manager of the hospital or institution in which the deceased
shall have died, shall so report to the medical examiner of the county
in which the death occurred, and request an inquest.
(b) The inquests authorized and required by this Article shall be
held by the medical examiner of the county in which the death occurred.
(c) In making such investigations and holding such inquests, the
medical examiner or an authorized deputy may administer oaths and take
affidavits. In the absence of next of kin or legal representatives of
the deceased, the medical examiner or authorized deputy shall take
charge of the body and all property found with it.
