  • Forensic pathology
  • It is the application of the knowledge of

  • Post-mortem examinations, deducing the cause of
    death by looking at the state of internal organs,
    estimating the cause of death by doing
    histo-pathology of internal organs, etc. involves
    a thorough knowledge of pathology

Medical Jurisprudence
  • Medical jurisprudence means legal aspects of
    practice of medicine.
  • For instance, a physician while prescribing
    medicines for his patients is guided by certain
    rules and regulations.
  • If he is negligent towards his patients, he may
    have to face the law.

    another doctor.
  • He is also expected to see him out of turn. If he
    follows these guidelines, he is said to have
    observed proper medical etiquette

Case Study
The autopsy
  • Autopsy was done on the dead body of the thirty
    years old lady, who was noticed hanging from the
    bough of a keekar tree in a forest. The
    deceased was a divorced lady.
  • A shawl was tied around her neck, which belonged
    to the deceased.
  • As a slip-noose was used, ligature was in contact
    with the skin throughout the full circumference
    of the neck.

The cause of Death
  • There was mark of saliva dribbling from the left
    angle of her mouth. Except over the uppermost
    part of the right side of the neck ligature mark
    was faint and deficient on the back and sides. It
    was believed to correspond to the ligature
    material as soft as shawl. There was evidence of
    bruising on and around carotid vessels on the
    right side.
  • She had abrasions on the upper front of her both
    legs and also over right side lower outer front
    of the abdomen. There was no bony injury in the
    air passages like the fracture or dislocation of
    the hyoid or thyroid indicative of manual
  • Cause of death by all standards was hanging.

The missing earrings
  • Doubt of homicide gained footings because father
    of the deceased held that earrings, that the
    deceased was always wearing, were missing from
    her ears. So much so the rumor of missing earring
    had converted in to news of recovery and seemed
    to have reached police ears while autopsy was
    going on.
  • Police expected autopsy doctors to provide some
    vital clues regarding the nature of hanging.
    Dismissing earrings based homicide theory autopsy
    team apprised police, true her ears were without
    any earring but there was no fresh or recent
    injury in her ears.
  • Ligature mark was believed to be the result of
    hanging, from a low point, for little period and
    in such a position that her legs were touching
    the ground. How could the body examination
    exclude that she could not and did not hang
    herself still appeared mysterious to the autopsy

The Recovery of new evidence
  • Absence of earring in the ears of the deceased
    was not given much credence till it was recovered
    from the killers.
  • Villagers handed over two boys to the police who
    were found selling the earrings of the deceased.

The confession
  • They confessed that one of them raped her. They
    then rendered her unconscious during throttling.
  • They also confessed of having created a scene of
    hanging. According to them in her efforts to
    escape she even fell and sustained some injuries
    on the front of her legs. Just because she
    removed her earrings herself to offer them for
    letting her go there was no injury on her ears.
  • They suspended her for two reasons. First they
    had doubt that she had not died and was still
    alive. They were so skeptical about her death
    that even after hanging her, one of them came
    back to the scene after sometime to make sure
    that she was really dead.
  • Another reason for hanging her, they told, was
    that they knew by creating a scene of hanging,
    even if she was noticed no one would suspect
  • A divorced young lady in the village would have
    several reasons to commit suicide.
