4. 1. INTRODUCTION
• Disaster reason even tree chocolates all over certain without
any warning.
• A mass disaster is a catastrophic event of such a magnitude
or severity that cause heavy loss to human life and property.

6. 2. TYPES OF DISASTERS
Mass disaster could be of the following types:
• Natural – floods, cyclones, earthquakes, drought.
• Accidents – rail, air, road, sea, fire etc.
• Industrial – gas leaks, explosions .
• Man made – roits, war, terrorist attack.

7. 3.Management of Mass disaster
• Coordination
• Infectious disease risk
• Body recovery
• Storage of dead bodies
• Identification of dead bodies
• Information management
• Long term storage and disposal of dead bodies
• Communication and the media
• Support to families and relatives

8. • Team work is one of the keys to success
in disaster management
A well coordinated team consists of:
• Police service
• Ambulance service
• Fire service
• Forensic examiners team
• Social worker and volunteers

9. Forensic examiners team consist of:
• Forensic pathologist
• Forensic odontologist
• Fingerprint experts
• Ballastics experts
• Other experts, relevant to the nature of the disaster.

10. 4.ROLE OF FORENSIC TEAM
A.IDENTIFICATION OF VICTIMS :
To identify each and every portion of the remains recovered from the disaster site
provided.
1. That there is sufficient intact DNA Present to obtain a DNA type
2. A reference sample is available for comparison purposes from a surviving
family member of some variable personal item containing biological material.
• Identify the cause of death
• Assist in reconstruction of the cause of disaster

11. B. Examination of scene of
disaster
• Barricade the disaster site
• Take photographs of the site
• Prepare a sketch plan of the site, showing parts of the wreckage and position of the
bodies.
• Search for blood strain, fingerprint, identity card, remain of explosive material in
case of explosions.
• Locate each body and label it with a “mass casuality card”, giving it serial number.
• Mutilated bodies and fragmentary remains should also be labelled and numbered.

13. 1.Introduction
Why identify remains?
• Help reconstruct the crime scene by determining everyone that was
present.
• For the official death certificate to be issued requires positive proof
that the remains were found and identified.
• Giving the victim’s family members closure and information.

14. 2.By photographers
3.Examination of clothing
4.External examination
5.Radiographic examination
6.Diagnosis of the types of
injuries
7.Dental examination
8.DNA profiling or
fingerprints
9.Histological examination

15. C. CAUSE OF DEATH
• Compile the salient gross post-mortem finding of majority of bodies.
• Study the special investigation results and correlate with the morbid
findings.
• Give opinion as to the cause of death based on the above and nature of
disaster.

16. D. CAUSE OF DISASTER
• Medical opinion,in this regards can only be partial and contributory to other
investigations.
• However, an opinion regarding the cause of disaster may be given in the case of
aviation disaster, train mishap and vehicular accidents,based on the following data:
(a) Autopsy finding of the body of pilot/driver
1. Evidence of organic disease, like coronary occlusion, cerebrovascular accident
or any other disease which could produce sudden collapse or blunting of
mental faculties
2. Evidence of gun-shoot injuries (air piracy).

17. 5. CASE STUDY
*Mumbai bomb blasts in 1993
• Bomb blast in 1993 was one of the worst and most cruel acts of
terrorism the world would have recorded.
• A series of bomb-blast took place at 12 different places killing and
disabling hundred of people within a span of one hours
• The explosive RDX was mainly placed in a car or vehicles and
detonated by pencil times.

18. • The exhibits collected from the 12 crime places were more or less
similar in nature namely debris from craters, ceiling,walls scrapping,
damaged vehicle parts, broken glass pieces, burnt cloth piece, mental
piece used as missile.
• About 25 different cases were received in the forensic science lab
mumbai.
• It is believed that the perpetrators were under world criminal groups.
