As has been stated above, every autopsy should be conducted as if it were a medicolegal case, and autopsy-protocols should be so complete and accurate that they may be accepted as evidence in any case in which such testimony can be introduced. While the ordinary autopsy may give satisfactory evidence as to the nature of the pathologic processes found and the cause of death, the scope of a medicolegal autopsy includes not only the cause and manner of death, but also the identification of the body, the determination of the commission of a crime, the manner in which the crime was performed, its motive and the detection of the criminal. Under such conditions the prosector must extend the field of his observations and conclusions to meet the possibilities of the witness-stand. The general technique of the medicolegal autopsy will vary but little from that of the ordinary, and these variations will be given here, as follows:— The medicolegal autopsy should always be performed in the presence of two witnesses, one of whom should be a physician competent to judge of the methods employed in the autopsy. The autopsy findings should be dictated during the progress of the autopsy, and at its close should be verified and signed in the presence of the witnesses. No other spectators should be permitted in the room. The examination should be made by daylight, and not until positive signs of death appear. If the cadaver has been frozen it must first be allowed to thaw out at room-temperature. The prosector should, if possible, see and examine the body before it is removed from the place where it is found, and he should carefully examine the surroundings, clothes and external surface of the body for possible clues. All known information concerning the circumstances of the case, the personal history of the deceased, the occurrence of any injury, previous illness, etc., should be in the hands of the prosector. Undertaker’s manipulations, such as the injection of embalming fluids, puncture of intestines, aspiration of fluid-contents, etc., must not be permitted before the autopsy.
