1

when does early postmortem occur

within the first 48 hours of death

2

stages of early post mortem

-algor mortis
-livor mortis
-rigor mortis

3

algor mortis

when the temperature of the body cools to the temperature of the environment

happens more quickly if nude or in a warmer environment

4

livor mortis

the bodily fluids sink to the bottom, causing body to turn the colour of a bruise

occurs 2 hours after death

5

rigor mortis

muscles begin to stiffen about ten minutes after death due to lack of oxygen

facial muscles first then rest of body

process complete in 24 hours

2 days until decomp

6

STAGES OF DECOMPOSITION STATE:

-early post mortem
-putrefaction
-black putrefaction
-butyric putrefaction
-dry decay
-skeletonization

7

define decomposition

breaking down of the body's biological and chemical elements,

body decomp is affected by heat weather location, insect and animal activity, clothing and exposure to elements

8

tapophony

the study of what happens to remains after death

helps answer the questions when where and how the person died as well as who killed them

9

early post mortem

-cells and organs stop receiving oxygen
Release enzymes and bacteria into the body
-enzymes break down the internal tissue
-insects break down body from outside
-they enter the body and lay eggs-->maggots

Body still human

10

Putrefaction

-insects continue to break down body
-causing buildup of gases--> bloating--> bursting of some body parts-->smell of death--> relaease of hair mat-->internal organs leak put of body as thick black liquid

11

Black Putrefaction

Body collapses due to buildup of gases

12

Putrefaction

-insects continue to break down body
-causing buildup of gases--> bloating--> bursting of some body parts-->smell of death--> relaease of hair mat-->internal organs leak put of body as thick black liquid

13

Black Putrefaction

Body collapses due to buildup of gases
Remaining flesh turns black and emits fume due to bacterial activity

Purge fluid releases which causes a dark greasy stain around body

14

Butyric fermentation

Remaining tissue ferments and dries into bone

Part of body in contact wit ground gets mouldy

15

Dry decay

Body is now dry and decays slowly, eventually everything disappears and only bone is left

16

Types of injuries

Antemortem
Perimortem

17

Antemortem

Broken bones have callouses on them and depending on callus growth age of break can be determined
