VARIOUS STAGES
OF
DECOMPOSITION---
7 STAGES OF
DECOMPOSITION:
1.IMMEDIATE STAGE
2. LIVOR MORTIS
3. RIGOR MORTIS
4. PUTREFICATION
5. ENTHAMOLOGY
6. MUMMIFICATION
7. SKELETINISATION
IMMEDIATE STAGE
Begins immediately after death
All physiological function stops
LIVOR MORTIS
Begins after 20-30 min of death
Blood settles down under gravity
Cause purplish discoloration
RIGOR MORTIS
•Initiates after 12-24 hrs
•Stiffening of body muscles
•Stiffness disappear after 36 hrs
PUTREFICATION
Time line : 2-3 days /2-3 weeks
Liquefaction of most organs
Abdomen begins to swell
Discoloration of abdomen
ENTAMOLOGY
Eggs are lied within 2 hrs
Life cycle of a fly from egg to maggot
to fly takes from 2-3 weeks
MUMMIFICATION
Initiates from 5 – 15 days
Flesh eventually turn similar to wax
Completed within a span of 3-12
months
SKELETONIZATION
Soft tissues dried and
decay
Parts of skeleton are visible
CONCLUSION
There are 7 stages of
decomposition
Timeline of each stage varies from
country to country
It may be also influenced by
topography and environmental
conditions
