What information can a forensic entomologist provide at the death scene?

Posted in Forensic Entomology & DNA Barcoding by paibiopai on November 23, 2009

Forensic entomologists are commonly called upon to determine the postmortem interval or “time since death” in homicide investigations.  More specifically, the forensic entomologist estimates a portion of the postmortem interval based on the age of the insect present.  This entomological based estimation is most commonly called the “Time Since Colonization”.  Based on the factors in a particular investigation, this may, or may not, closely approximate the entire postmortem interval.  In either case, it is the duty of the Forensic Pathologist, Medical Examiner, or Coroner to estimate the postmortem interval, and the Forensic Entomologist may assist them in providing information on the “time since colonization”, which can ultimately be used to substantiate a portion of the postmortem interval.

The forensic entomologist can use a number of different techniques including species succession, larval weight, larval length, and a more technical method known as the accumulated degree hour technique which can be very precise if the necessary data is available.  A qualified forensic entomologist can also make inferences as to possible postmortem movement of a corpse.  Some flies prefer specific habitats such as a distinct preference for laying their eggs in an outdoor or indoor environment.   Flies can also exhibit preferences for carcasses in shade or sunlit conditions of the (more…)

Common Insects found as Entomological Evidence -forensic entomology-

Posted in Forensic Entomology & DNA Barcoding by paibiopai on November 23, 2009

Acari

The Acari, or mites as they also are called, are small organisms, usually less than a mm in length. Mites occur under the dead body in the soil, during the later stages of decay. Many mites are transported to the body via other insects, such as flies or beetles. Other mites are soil dwelling forms which can be predators, fungus feeders or detritus feeders. Most species will be found in soil samples from seepage area under the body.

Aranea

The Aranea or spiders are predators on insects occurring on bodies. No species is specific to the carrion fauna, and will have limited or no value in estimation of the PMI.

Diptera

The order diptera contains insects with one pair of wings, the second ones modified to halteres. About 100,000 species are known to science, many more awaits discovery. Among the flies we find many members of the carrion fauna. The larvae of flies lives in very different habitats, also aquatic.

 

 

 

 

 

NEMATOCERA

Trichoceridae

Trichocera sp.

or winter-gnats as they also are called because the common species Trichocera regelationis, T. saltator, T. maculipennis, etc, fly abundantly in the winter months, although they occur at lower frequencies throughout the year. The adults resemble small crane-flies. The larvae are saprophagous and feed on decaying material. Trichocerid larvae constitutes an important part of the carrion fauna during the winter months, when the blowfly fauna are missing.

BRACHYCERA

Stratiomyidae

Larvae of Hermetia illucens is recorded eating on human excrement and human remains. Usually this species occur late in the decomposing process

Using forensic entomology to determine whether the body has been moved after death

Posted in Forensic Entomology & DNA Barcoding by paibiopai on November 23, 2009

After death, a succession of fungi, bacteria and animals will colonize the dead body. The substrate on which the body is lying will also change over time. Leakage of fluids from the dead body will lead to the disappearance of certain insects, and other insects will increase as the time goes. A forensic entomologist can then look for how long the body has been there by looking at the fauna at the body, and also estimate the time the body has been lying there by sampling soil insects underneath the dead body. If there is a difference in the estimates, and the analysis of the soil suggests a short PMI, and the analysis of the body fauna suggests (more…)

Finding the Cause of Death using Forensic Entomology

Posted in Forensic Entomology & DNA Barcoding by paibiopai on November 20, 2009

In a crime investigation, there is not only of great interest to find out when a victim died, but also of interest to find out how the victim died, as this can be used to find the killer.

In some instances the insects themselves are the killers, in other instances the insects occuring on the carrion can shed a light on what happened when the victim died.

Wasps and bees, for example, can inject venom through a sting. Some people are sensitive and allergic to these venoms, and can die if not treated in time. One other important aspect of wasps and bees are their effect on drivers. Many car accidents are probably caused by some wasp, bee or bumble-bee coming through the window, causing hysteria, or a distraction from the road leading to a collision or other accidents. In some cases wasps and bees has been used as murder weapons,  (more…)

What happen after death ? -pathology physiology forensic-

BCSO-What happens after death?

Everybody will die, that is one thing that we are absolutely certain of. What exactly is death, and what happens in the time after death? From a biological point of view, death is a process, not an event. This is because the different tissues and organs in a living body dies at different rates. We can divide death into somatic death and cellular death. Somatic death is when the individual is not longer a unit of society, because he is irreversibly unconscious, and unaware of himself and the world.

Cellular death is when the cells quits respiration and metabolism. When all cells are dead, the body is dead. But all cells do not die simultaneously, except perhaps in a nuclear explosion. Even in a victim of a car bomb, where the body becomes fragmented, individual cells will continue to live for a few minutes or longer. Different celltypes can live for different times after cardiac arrest. Nervous cells in the brain are particulary vulnerable to oxygen deprivation and will die within 3-7 minutes after (more…)

Estimating Time of Death with Forensic Entomology

Posted in Forensic Entomology & DNA Barcoding by paibiopai on November 20, 2009

After the initial decay, and the body begins to smell, different types of insects are attracted to the dead body. The insects that usually arrives first is the Diptera, in particular the blow flies or Calliphoridae and the flesh flies or Sarcophagidae.

The females will lay their eggs on the body, especially around the natural orifices such as the nose, eyes(2), and ears(2). If the body has wounds the eggs are also laid in such. Flesh flies do not lay eggs, but deposits larvae instead.

After some short time, depending on species, the egg hatches into a small larvae. This larvae lives on the dead tissue and grows fast. After a little time the larva molts, and reaches the second larval instar. Then it eats very much, and it molts to its third instar. When the larvae is fully grown it becomes restless and begins to wander. It is now in its prepupal stage. The prepupae then molts into a pupae, but keeps the third larval instars skin, which becomes the so-called puparium. Typically it takes between one week and two weeks from the egg to the pupae stage. The exact time depends on the species and the temperature in the surroundings.

The theory behind estimating time of death, or rather the post mortem interval (PMI for short) (more…)
