PsychopathyPsychopathy is a mental health condition characterized by persistent antisocial behavior, impaired empathy and remorse, and bold, disinhibited, and egotistical traits. Different conceptions of psychopathy have been used throughout history that are only partly overlapping and may sometimes be contradictory. Hervey M. Cleckley, an American psychiatrist, influenced the initial diagnostic criteria for antisocial personality reaction/disturbance in the Diagnostic and Statistical Manual of Mental Disorders (DSM), as did American psychologist George E.
Offender profilingOffender profiling, also known as criminal profiling, is an investigative strategy used by law enforcement agencies to identify likely suspects and has been used by investigators to link cases that may have been committed by the same perpetrator. Multiple crimes may be linked to a specific offender and the profile may be used to predict the identified offender's future actions. The first offender profile was assembled by detectives of the Metropolitan Police on the personality of Jack the Ripper, a serial killer who had murdered several prostitutes in the 1880s.
DetectiveA detective is an investigator, usually a member of a law enforcement agency. They often collect information to solve crimes by talking to witnesses and informants, collecting physical evidence, or searching records in databases. This leads them to arrest criminals and enable them to be convicted in court. A detective may work for the police or privately. Informally, and primarily in fiction, a detective is a licensed or unlicensed person who solves crimes, including historical crimes, by examining and evaluating clues and personal records in order to uncover the identity and/or whereabouts of criminals.
Forensic psychologyForensic psychology is the practice of psychology applied to the law. Forensic psychology is the application of scientific knowledge and methods to help answer legal questions arising in criminal, civil, contractual, or other judicial proceedings. Forensic psychology includes research on various psychology-law topics, such as jury selection, reducing systemic racism in criminal law, eyewitness testimony, evaluating competency to stand trial, or assessing military veterans for service-connected disability compensation.
Jack the RipperJack the Ripper was an unidentified serial killer active in and around the impoverished Whitechapel district of London, England, in 1888. In both criminal case files and the contemporaneous journalistic accounts, the killer was called the Whitechapel Murderer and Leather Apron. Attacks ascribed to Jack the Ripper typically involved women working as prostitutes who lived and worked in the slums of the East End of London. Their throats were cut prior to abdominal mutilations.
VampireA vampire is a mythical creature that subsists by feeding on the vital essence (generally in the form of blood) of the living. In European folklore, vampires are undead creatures that often visited loved ones and caused mischief or deaths in the neighbourhoods which they inhabited while they were alive. They wore shrouds and were often described as bloated and of ruddy or dark countenance, markedly different from today's gaunt, pale vampire which dates from the early 19th century.
Forensic scienceForensic science, also known as criminalistics, is the application of science to criminal and civil laws. During criminal investigation in particular, it is governed by the legal standards of admissible evidence and criminal procedure. It is a broad field utilizing numerous practices such as the analysis of DNA, fingerprints, bloodstain patterns, firearms, ballistics, and toxicology. Forensic scientists collect, preserve, and analyze scientific evidence during the course of an investigation.
TortureTorture is the deliberate infliction of severe pain or suffering on a person for reasons such as punishment, extracting a confession, interrogation for information, or intimidating third parties. Some definitions are restricted to acts carried out by the state, but others include non-state organizations. Torture has been carried out since ancient times. In the eighteenth and nineteenth centuries, Western countries abolished the official use of torture in the judicial system, but torture continued to be used throughout the world.
Organized crimeOrganized crime (or organised crime) is a category of transnational, national, or local groupings of highly centralized enterprises run by criminals to engage in illegal activity, most commonly for profit. While organized crime is generally thought of as a form of illegal business, some criminal organizations, such as terrorist groups, rebel forces, and separatists, are politically motivated. Many criminal organizations rely on fear or terror to achieve their goals or aims as well as to maintain control within the organization and may adopt tactics commonly used by authoritarian regimes to maintain power.
