Case Presentation I
Deceased Abdul Hafeej aged 54 years was admitted to
the hospital in unconscious state with the history of
ingestion of massage oil named ‘Rogan Phosphorous’

So, according to viscera analysis the death was
declared as Homicidal.

adequate amount in wide mouth
glass bottles, lid should be tightly
closed, labeled and sealed.
Bottles should be filled only 2/3rd
and the remaining 1/3rd is left for
the gases formed in the bottle.
All bottles are then kept in

Case Presentation II
Napoleon Bonaparte after the defeat at
the battle of Waterloo in 1815, was
exiled to St. Helena where six years
later he died a mysterious death.
The British claimed his death to be
due to Stomach Cancer; however the
symptoms described by his personal
physician Dr.Antommarchi were
strongly suggestive of Chronic Arsenic
Immediately after the death of Napoleon, his valet cut
some hair from the scalp and gave it to
Dr.Antommarchi, which were then submitted to
Harwell Nuclear Research Lab in London.
Neutron activation analysis was done, which revealed
fluctuating levels of Arsenic from 4.4 to 33.3 ppm,
while any level above 10 ppm is indicative of significant
Henceforth, this indicates the importance of
preservation of viscera in determining the cause of
