Offender profiling

Offender 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. There are multiple approaches to offender profiling, including the FBI's typological method, geographic profiling, and investigative psychology, each utilizing different techniques to analyze offender behavior. Profiling is primarily applied in cases involving violent crimes such as serial murder, sexual offenses, and arson, where behavioral patterns may provide investigative leads. Despite its use in law enforcement, offender profiling remains controversial, with critics arguing that it often lacks empirical validation, relies heavily on subjective interpretation, and may contribute to cognitive biases in criminal investigations. Advances in forensic psychology and data-driven methodologies continue to shape the field, integrating psychological theories with statistical analysis to improve reliability and accuracy. The originator of modern profiling was FBI agent Robert Ressler. He defined profiling as the process of identifying all psychological characteristics of an individual and forming a general description of their personality based on an analysis of crimes they have committed.

History The earliest reference to the use of profiling, according to R.S. Feldman, is Quintilian's essay "Instruction to the Speaker", written in the 1st century AD. It included information about gestures used by people at that time. M. Woodworth and S. Porter believe that the first development on the topic of profiling that should be considered is the notorious Malleus Maleficarum ("Hammer of Witches"), written in the 15th century, since it contains psychological profiles of alleged witches. There is also an opinion that the first "professional profiler", albeit a fictional one, was C. August Dupin, the protagonist of Edgar Allan Poe's short story The Murders in the Rue Morgue (1841), who constructed a psychological portrait of the killer. A factual work related to profiling with a scientific approach was Charles Darwin's book, The Expression of Emotions in humans and animals (1872). It contained only a description of external manifestations, but it was a systemization, and thus the beginning of a scientific study of the subject. An Italian psychologist Cesare Lombroso (1835-1909) was a criminologist who attempted to formally classify criminals based on age, gender, physical characteristics, education, and geographic region. When comparing these similar characteristics, he better understood the origin of motivation of criminal behavior, and in 1876, he published the book The Criminal Man. Lombroso studied 383 Italian inmates. Based on his studies, he suggested that there were three types of criminals: born criminals, degenerate criminals and insane criminals who suffered from mental illness. Also, he studied and found specific physical characteristics; some examples included asymmetry of the face, eye defects and peculiarities, ears of unusual size, etc. One of the first offender profiles was assembled by detectives of the Metropolitan Police on the personality of Jack the Ripper, a serial killer who had murdered a series of prostitutes in the 1880s. Police surgeon Thomas Bond was asked to give his opinion on the extent of the murderer's surgical skill and knowledge. Bond's assessment was based on his own examination of the most extensively mutilated victim and the post mortem notes from the four previous canonical murders. In his notes, dated November 10, 1888, Bond mentioned the sexual nature of the murders coupled with elements of apparent misogyny and rage. Bond also tried to reconstruct the murder and interpret the behavior pattern of the offender. Bond's basic profile included that "The murderer must have been a man of physical strength and great coolness and daring... subject to periodic attacks of homicidal and erotic mania. The characters of the mutilations indicate that the man may be in a condition sexually, that may be called Satyriasis." In 1912, a psychologist in Lackawanna, New York delivered a lecture in which he analyzed the unknown murderer of a local boy named Joey Joseph, dubbed "The Postcard Killer" in the press. In 1932, Dr. Dudley Schoenfeld gave the authorities his predictions about the personality of the kidnapper of the Lindbergh baby. In 1943, at the request of the US Office of Strategic Services, psychiatrist Walter C. Langer developed a profile of Adolf Hitler that hypothesized the Nazi dictator's response to various scenarios, including losing World War II. After the war, British psychologist Lionel Haward, while working for the Royal Air Force police, drew up a list of characteristics that high-ranking war criminals might display. These characteristics were used to identify high-ranking war criminals amongst captured soldiers and airmen. James Brussel was a psychiatrist who rose to fame after his profile of New York City's "Mad Bomber" George Metesky was published in the New York Times in 1956. The media dubbed him "The Sherlock Holmes of the Couch." In his 1968 book, Casebook of a Crime Psychiatrist, Brussel relates how he predicted that the bomber would wear a buttoned-up double-breasted suit, but removed the many incorrect predictions he had made in his profile, claiming he had successfully predicted that the bomber would be a Slav who lived in Connecticut, when in fact, he had actually predicted he would be "born and educated in Germany," and live in White Plains, New York. In 1964, Brussel profiled the Boston Strangler for the Boston Police Department.
