The state of the eyes, if not too decomposed, may still become a sign of identity. For instance, the color of the iris, an arcus senilis, a pterygium, a cataract or an operation for the same, an iridectomy, etc., are signs that occasion may utilize.
The TRUNK may show, as it has in several instances, incised wounds that caused death before the mutilation. Besides, the organs therein contained may by their weight, dimension, and tissue alteration indicate the progress of age and of degeneration. Modifications of the circulatory and respiratory apparatus are obviously characteristic. As age advances the only organ whose weight increases with the number of years, the heart, may become hypertrophied or dilated; its coronary arteries may undergo an alteration; the pericardium thickens, and in fact arterial atheroma and degeneration generally may begin between thirty-five and forty years. It should, however, be borne in mind that these signs of senility may come much later or even not at all. In a man of eighty-four years Tourdes found no notable tissue lesion; in another of one hundred and four Lobstein found no trace of ossification of the arteries of the trunk and upper extremities, and in Thomas Parr, aged one hundred and fifty-two years, Harvey found absolutely no lesion of this kind. Although toward eighty years the heart increases in weight in both sexes, the opposite has been observed in exceptional cases. Placing the average weight of this organ in the adult at 266 grams for men, 220 for women, it will be found that progress in weight gives toward the eightieth year an increase of 90 grams for men and 60 for women. Yet a case of cardiac atrophy is reported in a woman of eighty whose heart weighed but 170 grams.
Diminished weight of the lungs becomes accentuated with years. Especially is this the case after pseudo-melanosis and senile emphysema. The state of the lungs of stone-cutters and miners and various thoracic and abdominal diseases may likewise become signs of identity. A cirrhosed liver, an enlarged spleen, a senile kidney, and the like, are sufficiently obvious in their bearings on this question.
Like the trunk, the ARMS AND LEGS, in cases of the class under consideration, show but few traces of disfigurement other than the fact of their having been disjointed. The manner in which the sections were made and the proceedings employed for the disarticulation would equally affirm an experienced hand or the reverse. Such facts have of late years assisted in the discovery and condemnation both of a farmer and of a medical student, and also in the case of the cook already mentioned, who cut off her child’s arm after the manner of carving the wing of a fowl. The existence of deformity, injury, and disease in the limbs should, of course, claim attention, but their relativity in an investigation of the kind is too apparent to require further comment.
Mutilation of the GENITAL ORGANS is not so common. Persons familiar with border warfare have observed the savage custom of cutting off the victim’s penis and placing it in his mouth. In more civilized communities the culprits are generally women in whom hatred and ferocity prompt an act that marks the evident satisfaction sought by the destructive instinct. Sometimes, however, the genital organs have been cut from the cadaver of a woman, presumably for the purpose of concealing traces of rape that may have preceded the murder. The signs furnished by the female genital organs as to virginity, maternity, and the menopause are so easily demonstrated at the necropsy as to become positive proofs of identity. The uterus loses both in size and weight with age. This along with hard, atrophied, and germless ovaries attests the stoppage of menstruation. The question of identity may turn on the age at which menstruation ceases, as happened in an action of ejectment in the case of Doe on the demise of Clark vs. Tatom. The period known as change of life, when the uterus and ovaries lose their function, though placed at forty-five and fifty years, is quite uncertain. In spite of averages, menstruation is occasionally continued to seventy and upward.[585]
The signs furnished by the genital organs of the male are of less importance. Atrophy and diminished weight of the testicles and rarity or absence of the spermatozoids are indications of senility; although spermatozoids have been observed at ninety-four years. The structure of the spermatic cord at different periods of life from the last of intra-uterine to the first of extra-uterine life, in puberty, and in old age, is accompanied by characteristic modifications of development and regression, which are of interest on the question of medico-forensic diagnosis of identity, as shown by Dr. Pellacani.[586]
Congenital deformity of the genital parts, as epispadias or hypospadias; marks of circumcision, useful in India to identify Mussulmans above eleven years; traces of disease that may have left extensive cicatrices, as phagadenic chancre, suppurating buboes, etc., may also furnish characteristics of evidential value.
ENTIRE CADAVER DEAD BUT A SHORT TIME.
In the case of a body that has been dead a short time only, recognition from the features, even by the nearest relatives, is often a matter of the greatest difficulty. The change produced in the color and form of the body, especially after drowning, is a formidable obstacle to identification by likeness and general type of face. Pages could be filled with the mere mention of the multiplied instances of mistaken identity of the living, many of whom have been punished because they had the misfortune to resemble some one else. How much more careful, then, should be the medical examination of the remains in the progress of decay, with the distortion and discoloration of the features, and the consequent change or destruction of the peculiar expression of the countenance by which human features are usually distinguished and identified.
