Legal case of post-morterm

 


Legal cases

  1. Poisoning
  2. Drowning
  3. Electric current/ electrocution
  4. Accidents
  5. Burns
  6. Eaten by or attack by wild animals

 

Protocol for legal case

ü  When legal case is there we need to follow common protocol for the legal protocol

ü  Panchanama – request letter from police,

ü  If you don’t have some necessary materials you may send demand note to police

ü  All necessary arrangement should be make available by the police in legal matter

ü  Collection of material protocol

ü  If carcass is completely autolized – need to carry the postmortem examination and collect what ever available in that dead body.

ü  Collect material as per the norms

o   In salt

o   In glycerin phosphate buffer

o   Alcohol/ spirit etc

ü  Seal it and hand over to police.


1.   Poisoning

ü  Mostly sudden death are there

ü  Congestion of all mucous membranes, serosae, mucosae, pin point hemorrhages on vital organs

ü  Left chamber of heart generally empty

ü  Don’t write name of any specific toxins unless you have laboratory report with you from authorized laboratory

ü  The lesions were suggestive of hypovolemic shock caused due to toxemia; however the final cause of death can be drawn after the report of forensic laboratory.

ü  This is to be write in any legal case, when you have sent the samples to forensic labs.

ü  E.g. urea poisoning, insecticide / pesticide


2.   Drowning

ü  You get dead body of animal floating in water

o   Well/ river/ pond etc.

ü  Need to differentiate based on lesions observed.

ü  Many people says – water, algae, sink in water etc. etc. sink test done by some peoples

ü  Just understand the mechanism of death when water / liquid enter into trachea/ respiratory tract.

ü  Basic inflammation rule- reaction of live tissue to the irritant.

ü  Lesions:

o   eyes are opened,

o   Trachea severely congested, edematous, hemorrhages in lungs, red colored froth in trachea and bronchi, emphysema of lungs at margins, pin point hemorrhages on endocardium, mesenteric blood vessels are engorged with blood.

o   Change in osmotic pressure in lung tissues, ruptured capillaries – blood in alvelolar lumens + mixed with water- hemolysis of blood– extensive movements of lung –churning of air and water- produce red colored froth

ü  If animal die before reach to water – no above lesions- clear water without redness,no emphysema no inflammations



Trachea severely congested, edematous, hemorrhages in lungs, red colored froth in trachea





3.   Electric current/ electrocution

ü  Entry point -exit point

ü  Many times no direct contact of live wire

ü  Circumstantial evidences need to be noted carefully (live wire on wet soil )

ü  180 Ampere current is sufficient to cause death in cow.

ü  Storms with electrocutions should be there

ü  Signs and lesions are observed in one animal but other animals did not showed any external lesions

ü  Electric spark – heavily charged electrons at centre, but areas around the spark is charged with electros and all the death phenomenon is observed due to these electrons.

ü  Around 20 to 25 feet area around the spark is charged with electrons.

ü  Spark may fall on one animal but animals around that spark are also found dead.

ü  Once electron enter into body all the conducting mechanisms is get increase thousand fold times- heart conduction, nerve impulses, voluntary and involuntary nerve tissues

ü  Disparity between heart and lung synchronization

ü  Hypovolemic shock and death.

ü  Eyes are open

ü  External marks may be / may not be present.

ü  Hemorrhages and blood clots in bronchus.

ü  Severe emphysema of lungs, hemorrhages

ü  Change in shape of heart scanty of blood clots in heart chambers.

ü  Mesenteric blood vessels are engorged

ü  This is true in all species including human  being.


 Mesenteric blood vessels are engorged


Change in shape of heart scanty of blood clots in heart chambers.


4.   Accidents


ü  Road accident- dead before accident of died  due to accident. (wild animals)

ü  Some tribal communities kill the animals by poisoning and throw them on high way

ü  Again same logic of inflammation

ü  Fractured portion will have inflammation around the surrounding tissues- musculature/ blood clots and inflammatory line

ü  The lesions were suggestive of hypovolemic shock due to mechanical injury.

ü  No need to write truck/ car/ bike etc.

ü  As can’t be diagnosed on post mortem lesions.

5.   Burns

ü  If carcass is burn completely and only char/ char coal is there

ü  One line report – carcass is completely charred due to burn.

ü  But problems with incompletely burned  carcass, many time to destroy the evidence  peoples are doing such things

ü  They may poison the animal and try to burn it  and want to show that died in burn.

ü  Again same basic logic of inflammation is to be applied- zone of inflammation, exudation etc.

ü  Eyes are bulged out, mouth cavity swollen and many carbon particles in the cavity, trachea will be edematous, inflamed and carbon particles in to the deeper portion of trachea  and bronchi.

ü  If all these lesions are there – then burn

ü  Absent – no burn.  

 

6.   Eaten by or attack by wild animals


ü  Many times to get compensation from govt. farmers throw their dead animals in jungle areas and will complaint to you that his animal  has been attacked by wild animals.

ü  As you reach to carcass you will get only part of skeleton.

ü  Ideally you need to say that -the organs are missing hence cause of death cannot be drawn. (Political issues)

ü  If whole body is there with injuries at neck/ jugular veins/ back

ü  You may say that animal by died due to hypovolemic shock caused due to hemorrhages, and these hemorrhages might be occurred due to unknown canines / wild animals. (Need all circumstantial evidences from forest department- foot print matching etc.)
