The Science of Death

What happens to our body when we die? • When did our victim die? • A way to find that out would be to investigate how long the body had been at the scene.

What happens to our body when we die? • Decomposition takes place after death. • It is a process that occurs naturally due to environmental factors

2 to 3 days after death….• The first stage after deaths occurs in 4 main phases:1. Algor Mortis Temperature drops to room temperature due to the absence of heat production by the body.

• Use either slide 6 or 7

2 to 3 days after death….• The first stage after deaths occurs in 4 main phases:2. Pallor Mortis Skin tone lightens as there is no more blood circulation.

2 to 3 days after death….• The first stage after deaths occurs in 4 main phases:3. Livor Mortis Due to gravity, blood settles at the lower resting part of the body. This gives a purplish blue appearance at regions where the body is resting on.

2 to 3 days after death….• The first stage after deaths occurs in 4 main phases:4. Rigor Mortis The body is unable to undergo aerobic respiration to produce energy. Muscles undergo permanent contraction (around 48-60 hours) until they start to breakdown

3-4 days after death…• Discoloration of skin spreads through the whole body.• Discoloured veins become visable

5-6 days after death….• Bacteria within the intestines start to respire anerobically.• This produce gases within the body, causing the body to bloat.

2 weeks after death….• Abdomen is fully bloated as internal gas pressure reaches maximum capacity

3 weeks….• Tissues soften due to decomposers acting on the body• Organs and cavities rupture.• Nails fall off

4 week after death….• Soft tissues begin to liquefy and face becomes unrecognizable.
