Wounds made during life might show the suggillation peculiar to bruises or traces of inflammation. Besides, the gaping nature of the lips of the wound, the fact of hemorrhage having taken place and the coagulation of the blood, the infiltration of blood into the cellular tissue, etc., are surgical facts that would leave but little doubt as to the infliction of the wounds during life.
The cause of death is often a difficult matter to determine, as it may have been accidental, suicidal, or the result of homicide. The causes relating thereto are, moreover, so many and varied that space and time compel a reference to other headings of this work. In forming an opinion as to the probable date of death the extent of putrefaction is the chief guide. If death is quite recent, we may be guided by the post-mortem rigidity or the extent to which the body has cooled. The march of putrefactive decomposition would, of course, be regulated by circumstances. It takes place very rapidly in persons who have succumbed to excessive fatigue or to any disassimilative excesses or derangement resulting in ante-mortem change of the tissues, such as those occurring in virulent or infectious diseases. The body of an infant decays more rapidly that that of an adult. The course of putrefactive phenomena is also influenced by the seasons, the extent of the exposure to air, and to other mesological causes. There is a manifest difference in the special putrefactive change accordingly as a body is buried in the earth, submerged in a fluid, thrown into a cesspool, or buried in a dung-heap.
In certain cases, especially where the body has been much mutilated, it may be desirable to know whether there was one or several murderers. While no definite rule can be laid down on this point, we are justified in supposing that there were two or more assassins when the body of the victim shows both gunshot and knife wounds, or that two persons were concerned in the dismemberment and mutilation of a body which shows the simultaneous presence of parts skilfully cut, while others show evident awkwardness.
Where there is more than one mortal wound on the same dead body, a question of medico-legal significance may arise. This occurred in the Burton murder case at Newport, R. I., in 1885, which gave rise to discussion of the following abstract question: “Whether it is possible for an individual, with suicidal intent, and in quick succession, to inflict a perforating shot of the head and another of the chest implicating the heart. Or, reversing the proposition, is it incredible that a person bent on self-destruction can, with his own hand, shoot himself in the heart and in the head?”
After consideration of the case referred to and reversal of the previous decision of the coroner, the supposed suicide proved to be a homicide. Yet if the abstract question of possibilities is alone regarded, there is no doubt of the fact that a suicide could shoot himself in such manner, both in the head and the heart, or, changing the order, of shots in the heart and in the head. The number of cases recorded establishes beyond a doubt the feasibility of the self-infliction of two such wounds, and make it clear that the theory of suicide may be maintained in such circumstances.[598]
JUDICIAL ANTHROPOMETRY.
Of late years the subject of anthropometric identification has taken such a place before justice that it cannot be ignored by the medical legist. The facts of scientific anthropology have here been applied in such a way as to establish with great certainty both the present and future identity of individuals who attempt dissimulation of their name and antecedents. The method used principally in the identification of criminals and deserters from the army has been adopted in the public service[599] and by most municipalities, with the exception of New York, where the subsequent identification of persons connected with municipal affairs has been and may be a source of no little embarrassment.
The system is based on three recognitory elements: photography, anthropometric measurements, and personal markings, from which a descriptive list is made that gives absolute certainty as to individual identity.
Owing to the illusory nature of photography and the difficulty in finding the portrait of any given individual in the large and constantly increasing collection of a “rogues’ gallery,” the matter has been simplified and facilitated by grouping the photographic collection according to the six anthropological coefficients of sex, stature, age, and color of the eyes. Each of these primordial groups is again subdivided in such a way as to reduce the last group to a small number, when the portrait is easily found and verified on comparing the measurements of the head, of the extended arms, the length of the left foot, and that of the left middle finger.
The photographic proof for each individual consists of two portraits side by side, one of which is taken full face, the other in profile of the right side. On the back of the photographic card is recorded with rigorous precision all personal markings or peculiarities.
