WHY TO INVESTIGATE
 SUCCESS OR FALIURE
 SEARCH BARE TRUTHS

PURPOSE
 WHAT HAS HAPPENED
 HOW IT HAPPENED
 WHO THE PERPETRATOR IS

MOTTO
 EVERYTHING AT THE SCENE PRIOR TO
EXPLOSION IS STILL IN EXISTENCE
UNLESS IT HAS BEEN VAPORIZED BY
EXPLOSION

TO WHOM TO DEPUTE
 CAPABILITY TO THINK THROUGH THE
SITUATIONS
 ABILITY TO STICK TO TASK
 INTELLIGENT, TALENTED, HONEST AND
TRUST WORTHY
 FREE HAND TO SELECT TEAM

SCHEMATIC ARTIST-DUTIES
 SKETCH AS PER TECHNIQUE
 DIMENSIONS OF EACH EVIDENCE
 CROSS CHECK MEASUREMENTS
 RECORD OF NECESSARY INFORMATION

Evidence custodian
 To collect evidence

Why it is required
 The only bare truth is
 EVIDENCES COLLECTED
 The best analytical method will be useless if
samples are not properly collected

What is Evidence
 Clues left at the site
 Residue of fire, debris, arson ,explosives
etc.
 Physical material collected from the site

 ANYTHING THAT CONNECTS THE
CRIME TO THE CRIMINAL

EVIDENCE COLLECTION
 WHAT TO COLLECT
 HOW TO COLLECT
 SAFETY PRECAUTIONS
 HOW TO LABEL AND PACK
 HOW TO FORWARD

CLASSIFICATION OF EVIDENCE
 MOVABLE EVIDENCE
 IMMOVABLE EVIDENCE
 CIRCUMSTATNTIAL EVIDENCE

 SECONDARY
FRAGMENTS
 PIECES OF INITIATING
DEVICES
 SPLINTERS
 SHATTERES OBJECTS
 PARTS OF DEVICES LIKE
