Forensic
Forensic science, also known as criminalistics, is the application of science to criminal and civil laws, mainly—on the criminal side—during criminal investigation, as governed by the legal standards of admissible evidence and criminal procedure. Forensic science is a broad field that includes; DNA analysis, fingerprint analysis, blood stain pattern analysis, firearms examination and ballistics, tool mark analysis, serology, toxicology, hair and fiber analysis, entomology, questioned documents, anthropology, odontology, pathology, epidemiology, footwear and tire tread analysis, drug chemistry, paint and glass analysis, digital audio video and photo analysis. Forensic scientists collect, preserve, and analyze scientific evidence during the course of an investigation. While some forensic scientists travel to the scene of the crime to collect the evidence themselves, others occupy a laboratory role, performing analysis on objects brought to them by other individuals.

Expert Witness
An expert witness, particularly in common law countries such as the United Kingdom, Australia, and the United States, is a person whose opinion by virtue of education, training, certification, skills or experience, is accepted by the judge as an expert. The judge may consider the witness's specialized (scientific, technical or other) opinion about evidence or about facts before the court within the expert's area of expertise, to be referred to as an "expert opinion". Expert witnesses may also deliver "expert evidence" within the area of their expertise. Their testimony may be rebutted by testimony from other experts or by other evidence or facts. History The forensic expert practice is an ancient profession. For example, in ancient Babylonia, midwives were used as experts in determining pregnancy, virginity and female fertility. Similarly, the Roman Empire recognized midwives, handwriting experts and land surveyors as legal experts. The codified use of expert witnesses and th ...

Song Ci
Song Ci (; 1186–1249) was a Chinese physician, judge, forensic medical scientist, anthropologist, and writer of the Southern Song dynasty. He is most well known for being the world's first forensic entomologist, having recorded his experience examining bodies for judicial cases in the ''Collected Cases of Injustice Rectified'' (''Xi Yuan Ji Lu''). Song Ci was born into a bureaucrat family in Jianyang (in modern Fujian Province). He served as a presiding judge in the high courts of the Song dynasty for several terms. During his post at a criminal court in Hunan Province, Song Ci personally examined the crime scenes each time he encountered a difficult case of homicide or physical assault. Song Ci combined historical cases of forensic science with his own experiences and wrote the book ''Collected Cases of Injustice Rectified'', the oldest known evidence of forensic entomology, with an eye to avoiding miscarriages of justice. The book was esteemed by generations of forensic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Collected Cases Of Injustice Rectified
''Collected Cases of Injustice Rectified'' or the ''Washing Away of Wrongs'' is a Chinese book written by Song Ci in 1247 during the Song Dynasty (960-1276) as a handbook for coroners. The author combined many historical cases of forensic science with his own experiences and wrote the book with an eye to avoiding injustice. The book was esteemed by generations of officials, and it was eventually translated into English, German, Japanese, French and other languages. It is the first ever written book of forensic science. Content Different versions of the book exist, but the earliest existing version was published during the Yuan Dynasty, containing fifty-three chapters in five volumes. The first volume describes the imperial decree issued by the Song Dynasty on the inspection of bodies and injuries. The second volume contains notes and methods on postmortem examinations. The third, fourth, and fifth volumes detail the appearances of corpses from various causes of death and meth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polygraph Test
A polygraph, often incorrectly referred to as a lie detector test, is a device or procedure that measures and records several physiological indicators such as blood pressure, pulse, respiration, and skin conductivity while a person is asked and answers a series of questions. The belief underpinning the use of the polygraph is that deceptive answers will produce physiological responses that can be differentiated from those associated with non-deceptive answers; however, there are no specific physiological reactions associated with lying, making it difficult to identify factors that separate those who are lying from those who are telling the truth. In some countries, polygraphs are used as an interrogation tool with criminal suspects or candidates for sensitive public or private sector employment. US law enforcement and federal government agencies such as the FBI, DEA, CIA, NSA, and many police departments such as the LAPD and the Virginia State Police use polygraph examinat ...

Drowning
Drowning is a type of suffocation induced by the submersion of the mouth and nose in a liquid. Most instances of fatal drowning occur alone or in situations where others present are either unaware of the victim's situation or unable to offer assistance. After successful resuscitation, drowning victims may experience breathing problems, vomiting, confusion, or unconsciousness. Occasionally, victims may not begin experiencing these symptoms until several hours after they are rescued. An incident of drowning can also cause further complications for victims due to low body temperature, aspiration of vomit, or acute respiratory distress syndrome (respiratory failure from lung inflammation.). Drowning is more likely to happen when spending extended periods of time near large bodies of water. Risk factors for drowning include alcohol use, drug use, epilepsy, minimal swim training or a complete lack of training, and, in the case of children, a lack of supervision. Common drowning lo ...

Confession (law)
In the law of criminal evidence, a confession is a statement by a suspect in crime which is adverse to that person. Some secondary authorities, such as Black's Law Dictionary, define a confession in more narrow terms, ''e.g.'' as "a statement admitting or acknowledging all facts necessary for conviction of a crime," which would be distinct from a mere admission of certain facts that, if true, would still not, by themselves, satisfy all the elements of the offense. The equivalent in civil cases is a statement against interest. History This specific form of testimony, involving oneself, is used as a form of proof in judicial matters, since at least the Inquisition. The value of confessions, however, are discussed, and law generally request cross-checking them with objective facts and others forms of evidence ( exhibits, testimonies from witnesses, etc.) in order to evaluate their truth value. Confessions were first developed in the Roman Catholic Church under the Sacrament of Pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ambroise Paré
Ambroise Paré (c. 1510 – 20 December 1590) was a French barber surgeon who served in that role for kings Henry II, Francis II, Charles IX and Henry III. He is considered one of the fathers of surgery and modern forensic pathology and a pioneer in surgical techniques and battlefield medicine, especially in the treatment of wounds. He was also an anatomist, invented several surgical instruments, and was a member of the Parisian barber surgeon guild. In his personal notes about the care he delivered to Captain Rat, in the Piémont campaign (1537–1538), Paré wrote: ''Je le pansai, Dieu le guérit'' ("I bandaged him and God healed him"). This epitomises a philosophy that he used throughout his career. These words, inscribed on his statue in Laval, are reminiscent of the Latin adage '' medicus curat, natura sanat''. Early life Paré was born in 1510 in Bourg-Hersent, near Laval, then part of the province of Maine, in northwestern France. As a child he watched, and was fir ...

Pathology
Pathology is the study of the causes and effects of disease or injury. The word ''pathology'' also refers to the study of disease in general, incorporating a wide range of biology research fields and medical practices. However, when used in the context of modern medical treatment, the term is often used in a narrower fashion to refer to processes and tests that fall within the contemporary medical field of "general pathology", an area which includes a number of distinct but inter-related medical specialties that diagnose disease, mostly through analysis of tissue, cell, and body fluid samples. Idiomatically, "a pathology" may also refer to the predicted or actual progression of particular diseases (as in the statement "the many different forms of cancer have diverse pathologies", in which case a more proper choice of word would be " pathophysiologies"), and the affix ''pathy'' is sometimes used to indicate a state of disease in cases of both physical ailment (as in ca ...

Strangulation
Strangling is compression of the neck that may lead to unconsciousness or death by causing an increasingly hypoxic state in the brain. Fatal strangling typically occurs in cases of violence, accidents, and is one of two main ways that hanging causes death (alongside breaking the victim's neck). Strangling does not have to be fatal; limited or interrupted strangling is practised in erotic asphyxia, in the choking game, and is an important technique in many combat sports and self-defense systems. Strangling can be divided into three general types according to the mechanism used: * Hanging—Suspension from a cord wound around the neck * Ligature strangulation—Strangulation without suspension using some form of cord-like object called a garrote * Manual strangulation—Strangulation using the fingers or other extremity General Strangling involves one or several mechanisms that interfere with the normal flow of oxygen into the brain: *Compression of the carotid arteries or ...

Entomology
Entomology () is the scientific study of insects, a branch of zoology. In the past the term "insect" was less specific, and historically the definition of entomology would also include the study of animals in other arthropod groups, such as arachnids, myriapods, and crustaceans. This wider meaning may still be encountered in informal use. Like several of the other fields that are categorized within zoology, entomology is a taxon-based category; any form of scientific study in which there is a focus on insect-related inquiries is, by definition, entomology. Entomology therefore overlaps with a cross-section of topics as diverse as molecular genetics, behavior, neuroscience, biomechanics, biochemistry, systematics, physiology, developmental biology, ecology, morphology, and paleontology. Over 1.3 million insect species have been described, more than two-thirds of all known species. Some insect species date back to around 400 million years ago. They have many kinds of ...

Manner Of Death
In many legal jurisdictions, the manner of death is a determination, typically made by the coroner, medical examiner, police, or similar officials, and recorded as a vital statistic. Within the United States and the United Kingdom, a distinction is made between the cause of death, which is a specific disease or injury, versus manner of death, which is primarily a legal determination versus the mechanism of death (also called the mode of death) which does not explain why the person died or the underlying cause of death and can include cardiac arrest or exsanguination. Different categories are used in different jurisdictions, but manner of death determinations include everything from very broad categories like "natural" and "homicide" to specific manners like "traffic accident" or "gunshot wound". In some cases an autopsy is performed, either due to general legal requirements, because the medical cause of death is uncertain, upon the request of family members or guardians, or ...
