An autopsy, also called a post-mortem examination, is a detailed and careful medical examination of a person's body and its organs after death to help establish the cause of death. The word autopsy is derived from a Greek word autopsia meaning 'seeing for oneself'. An autopsy is usually carried out within 48 hours after the death of a person. There are three levels of autopsy Complete - in which all body cavities are examined (including the head ) Limited - which may exclude the head Selective- where specific organs only are examined.

The-csi-effect and District Accreditation. Body burners: The forensics of fire - science-in-society - 22 May 2009. THE fire started with a match held under a cotton blanket close to the man's waist. Within 2 minutes, the flames had spread across the single bed he was lying on and were consuming his cotton sweatshirt and trousers. Around a dozen onlookers were at the scene - including police, fire investigators and death investigators - yet all they did was watch. That was, after all, their job. The "victim" had in fact died some time ago, having previously donated his remains to medical research. His body had reached a unique team led by Elayne Pope, a forensic scientist at the University of West Florida in Pensacola. “The Lindow Man” Forensic entomology.
Forensic Art. Forensic art is a law enforcement artistic technique used in the identification, apprehension, or conviction of wanted persons. Forensic art encompasses several disciplines including composite art, image modification, age progression, post-mortem reconstruction and demonstrative evidence. However, composite art is traditionally the most commonly known discipline of forensic art. The art of composite drawing has been used by police agencies throughout history. When one recalls the Old West, the classic wanted poster with a drawing of a "Bad Guy" comes to mind.
Composite Art is an unusual marriage of two unlikely disciplines, police investigative work and art. In the past twenty years, the discipline of composite art has evolved into forensic art.

Forensic Science, Crime Scene Investigations and Pathology at Explore Forensics (UK) The eyes have it (2/5/2008) Researchers can now determine when a human was born by looking into the eyes of the dead Using the radiocarbon dating method and special proteins in the lens of the eye, researchers at the University of Copenhagen and University of Aarhus can now establish, with relatively high precision, when a person was born.
This provides a useful tool for forensic scientists who can use it to establish the date of birth of an unidentified body and could also have further consequences for health science research. The findings are published in the online, open-access journal PLoS ONE on January 30. The lens of the eye is made up of transparent proteins called crystallins. These are packed so tightly together and in such a particular way, that they behave like crystals, allowing light to pass through the lens of the eye so that we can see. A minute quantity of Carbon (C-12) in the carbon-dioxide content of the atmosphere contains two extra neutrons and is therefore called Carbon-14 (C-14).
Forensic Blood Spatter from Sneezing. When working on a crime scene where blood spatter is in evidence, many things have to be done beginning from recording the scene, taking photographs, determining where the blood came from, from whom and how. One specific point that needs to be considered when doing so is to determine and separate bloodstains that may be caused by high velocity force such as that caused by sneezing. At the same time, if there is not a body present or if the body does not show evidence of blood in the nasal area, a history needs to be taken about the victim and how often or forcibly they may have had a nosebleed.
A basic understanding of blood spatter analysis allows those collecting and preserving blood evidence at the scene knows what to look for. If there are several areas of blood evidence, it is important to note and qualify the movement, location, position of persons or objects, the direction blood was traveling, the type of blood pattern, and from that, derive a sequence of events. Sources: Protect yourself from COFEE with some DECAF (Updated) In response to Microsoft's Computer Online Forensic Evidence Extractor (COFEE), which helps law enforcement officials grab data from password-protected or encrypted sources, two developers have created "Detect and Eliminate Computer Assisted Forensics" (DECAF), a counter intelligence tool designed to thwart the Microsoft forensic toolkit. DECAF monitors the computer it's running on for any signs that COFEE is operating on the machine and does everything it can to stop it.
More specifically, the program deletes COFEE's temporary files, kills its processes, erases all COFEE logs, disables USB drives, and even contaminates or spoofs a variety of MAC addresses to muddy forensic tracks. It can be told to disable almost every piece of hardware on a machine and delete pre-defined files in the background. The 181KB DECAF program even has a 'Spill the cofee' mode in which it simulates COFEE's presence to give the user an opportunity to test his or her configuration before actually using it.
