The weight of the body is multiplied by 1.3 (70x1.3=91kg)
Second line (blue) is drawn from center of circle trough the intersection with nomogram’s diagonal line (gray) all the way to the outer circle (95% confidence) and read the number ate intersection with 90kg line)
The discoloration of the body after death due to the gravitational settling of blood.
30 minutes after death
The skin gets purple and waxy
The lips, finger- and toe-nails fade to a pale color or turn white as the blood leaves.
The hands and feet turn blue
The eyes start to sink into the skull
HIPOSTASIS (LIVOR MORTIS OR LIVIDITY)
3-4 hours after death the stiffening of the body becomes apparent and the whole body becomes completely rigid after about 12 hours
Rigor mortis completely disappears after about 36 hours
Wounds permitting invertebrates easier access to internal body tissues
Surface burning causing skin to crackand thereby allowing easier access of invertebrates and oxygen to internal tissues
Suffering from septicaemia or myiasis before death
Body exposed to the environment above ground
Body resting on soil
How do forensic scientists determine the time of death?
The eyes of a victim can hold answers to the time of death, as a thin cloudy film is developed over the eye within 3 hours after death has occurred.
The digestive system and gut contents of a victim can provide important clues to the time of death of a victim. After 3 hours, the food then leaves the stomach and heads toward the small intestines. 6 hours after eating a meal, the food will have traveled half way through the small intestines and begin moving through the large intestine. Where the victim's small intestine is empty, it suggests that the victim ate his or her last meal approximately 8 hours before death.
Forensic Entymology Flies and maggots also provide an approximate time of death, very useful for cases where the body has been long dead. Only certain insects will feed and lay eggs on a dead corpse and forensic entomologists study these insects, their larvae cycles and thereafter can determine whether a body has been dead for just one day or up to 3 or 4 weeks.
Proteins and carbohydrates in the Blowflies e.g. Bluebottle flies, Syrphidae flies deceased body begin to break down. 4-7 days
Body is starting to decay and causes the Fly larvae and beetle e.g. Rove Beetles abdomen to inflate because of the gases inside.
Decay is well and truly setting in; the Ants, cockroaches, beetles and flies abdomen wall begins to break down. 19-30 days
The decaying body enters a stage know Beetles and mites e.g. Springtail beetle, Acari, as 'post-decay'; in wet, humid conditions, Nematocera (present only during the winter months), the body is sticky and wet; in hot dry Brachycera conditions, the body is dried out .
31 and over days The bones, skin and hair that remain no longer give off a powerful stench and smell just like the soil surrounding it.
