After hearing the testimony, the jury shall render its verdict and certify it by an inquisition in writing signed by the members of the jury, or the coroner shall render his decision if the inquest is by the coroner sitting without a jury, setting forth the name of the deceased, the time and place of death, the medical cause of death and whether the death was by (1) natural causes, (2) suicide, (3) accident, or (4) the hands of another person other than by accident. Such findings shall not include nor shall they make any reference to civil or criminal responsibility on the part of the deceased or any other person.
