the platysma and sterno-mastoid, are likely to be ruptured only when con-
siderable violence has been used in hanging. The inner and middle coats
of the carotid arteries may be found lacerated with extravasation of blood
within their walls, if there has
been a sudden drop as in judicial
hanging. Similarly, fracture or
dislocation of the upper cervical
vertebrae together with com-
pression or laceration of the
spinal cord may be noticed. In
rare instances, the processes of
the thyroid cartilage may be
fractured, but the hyoid bone is,
as a rule, not fractured.
The epiglottis is frequently con-
gested. The^ mucous membrane
of the trachea is found to be red
and congested containing a fine
bloody froth in some cases. Very
rarely, it is found to be lacerated

s.-^;rhe medico-legal questions likely to arise in
a case of hanging are
1. ^JQiether death was caused by hanging.
2. Whether the hanging was suicidal, homicidal or accidental.
1. Whether Death was caused by Hanging. — In India, it is a common
practice to kill a victim, and then to suspend the body from a tree or a rafter
to avert suspicion. It is, therefore, necessary to find out if hanging was the
cause of death in a suspended body.
Jhe_jpresence of a ligature-mark alone is not diagnostic of death from
hanging, inasmuch as, being a purely cadaveric phenomenon, it msfy be
produced if a body has been suspended after death. Casper x has illustrated
by experiments that a mark similar to one observed in persons hanged alive
can be produced if suspended within two hours or even a longer period after
death. Besides, a similar mark may also be produced by dragging a .body,
along the ground with a cord passed round the neck soon after death. ^S(>w-
ever, one can safely say that death was due to hanging, if, in addition to
the cord mark, there were trickling of saliva from the mouth, ecchymoses
and slight abrasions about the ligature-mark, laceration of the intima of
the carotid arteries with extravasation of blood within their walls and the
post-mortem signs of asphyxia, and if there were no evidence of the signs
of a struggle, fatal injuries, or poisoning.
