Gene Anthony “Rocky” Morrison (born 1958) was a fraudulent forensic detective who operated over three decades in the Hyde area of Greater Manchester , England , under the title Dr. Gene Morrison .
85-437: Memorable for his trademark sheepskin jacket, during the course of his deception, he managed to trick not only members of the public, but also many judges, lawyers and the police themselves, into believing he was a genuine expert in forensic science . During his trail held in 2007, he insisted on being referred to as Doctor throughout the entire trial, and the jury were supposedly reduced to laughter on many occasions throughout
170-460: A prisoner by means of pressure, torture (including enhanced interrogation techniques ) or other forms of duress , whether physical or psychological. Depending on the level of coercion used, a forced confession is not valid in revealing the truth. The person being interrogated may agree to the story presented to him or even make up falsehoods himself in order to satisfy the interrogator and discontinue his suffering. However, despite developments in
255-417: A confession includes: any statement wholly or partly adverse to the person who made it, whether made to a person in authority or not and whether made in words or otherwise. A confession may be admitted in evidence so long as it is relevant to any matter in issue and not excluded under the court's discretion. The court must exclude evidence: The court may exclude evidence: Under section 76 , following
340-417: A criminal leaves a trace. Alexander Lacassagne, who taught Locard, produced autopsy standards on actual forensic cases. Alphonse Bertillon was a French criminologist and founder of Anthropometry (scientific study of measurements and proportions of the human body). He used anthropometry for identification, stating that, since each individual is unique, by measuring aspects of physical difference there could be
425-613: A database. By the turn of the 20th century, the science of forensics had become largely established in the sphere of criminal investigation. Scientific and surgical investigation was widely employed by the Metropolitan Police during their pursuit of the mysterious Jack the Ripper , who had killed a number of women in the 1880s. This case is a watershed in the application of forensic science. Large teams of policemen conducted house-to-house inquiries throughout Whitechapel. Forensic material
510-452: A false confession is, it has been shown that confessions can affect other pieces of evidence and the way they are presented, which can affect a judge or jury's perception of guilt. Through debunking these myths it can be demonstrated that confessions cannot be the be-all-end-all in a criminal investigation, and the criminal justice system should implement more tactics and procedures that prevent false confessions from occurring. In English law
595-443: A flaw in the bullet that killed the victim and was able to trace this back to the mold that was used in the manufacturing process. The French police officer Alphonse Bertillon was the first to apply the anthropological technique of anthropometry to law enforcement, thereby creating an identification system based on physical measurements. Before that time, criminals could be identified only by name or photograph. Dissatisfied with
680-499: A major breakthrough and came to have tremendous importance in forensic science. The test was further refined for forensic use by the Swiss chemist Maurice Müller in the year 1960s. Forensic DNA analysis was first used in 1984. It was developed by Sir Alec Jeffreys , who realized that variation in the genetic sequence could be used to identify individuals and to tell individuals apart from one another. The first application of DNA profiles
765-541: A method to record them with printing ink. He established their first classification and was also the first to identify fingerprints left on a vial. Returning to the UK in 1886, he offered the concept to the Metropolitan Police in London, but it was dismissed at that time. Faulds wrote to Charles Darwin with a description of his method, but, too old and ill to work on it, Darwin gave the information to his cousin, Francis Galton , who
850-409: A more profound examination reveals that forensic intelligence represents a genuine and emerging inclination among forensic practitioners to actively participate in investigative and policing strategies. In doing so, it elucidates existing practices within scientific literature, advocating for a paradigm shift from the prevailing conception of forensic science as a conglomerate of disciplines merely aiding
935-609: A now well-known feature of crime scene examination. He used analytical chemistry for blood residue analysis as well as toxicology examination and determination for poisons. He used ballistics by measuring bullet calibres and matching them with a suspected murder weapon. Hans Gross applied scientific methods to crime scenes and was responsible for the birth of criminalistics. Edmond Locard expanded on Gross' work with Locard's Exchange Principle which stated "whenever two objects come into contact with one another, materials are exchanged between them". This means that every contact by

#17328762442781020-521: A personal identification system. He created the Bertillon System around 1879, a way of identifying criminals and citizens by measuring 20 parts of the body. In 1884, over 240 repeat offenders were caught using the Bertillon system, but the system was largely superseded by fingerprinting. Confession (law) In the law of criminal evidence , a confession is a statement by a suspect in crime which
1105-477: A question unreliable centers on whether it is likely to have made an innocent person confess, or even (equivalently) to have made a guilty person confess to more than their actual crime. "Anything said or done" is not limited to the actions of the police, but does not include things said or done by the accused. However, the circumstances existing at the time do include the accused's own mental state and capacities. The court may exclude evidence under section 76A of
1190-478: A representation by the defendant or upon the court's own motion, evidence tendered by the prosecution must not be admitted if it was or may have been obtained : Whether or not evidence was obtained in such circumstances will be decided by a judge sitting without a jury in a voir dire . Oppression includes torture, inhumane and degrading treatment and the use or threat of violence. Oppression imports "some impropriety... actively applied in an inappropriate manner by
1275-628: A revengeful or brooding condition of the mind, or that religious mania may have been the original disease but I do not think either hypothesis is likely". Handbook for Coroners, police officials, military policemen was written by the Austrian criminal jurist Hans Gross in 1893, and is generally acknowledged as the birth of the field of criminalistics. The work combined in one system fields of knowledge that had not been previously integrated, such as psychology and physical science, and which could be successfully used against crime. Gross adapted some fields to
1360-442: A scientific article "Confession Evidence: Commonsense Myths and Misconceptions" by Saul M. Kassin , five myths in the confession evidence system were identified. These myths are 1) trained interviewers can detect truth and deception; 2) Miranda protects the accused from interrogation; 3) people do not confess to crimes they did not commit; 4) police, prosecutors, judges, and juries can distinguish true and false confessions; and 5) it
1445-425: A suspected sample with hydrogen sulfide and hydrochloric acid . While he was able to detect arsenic as yellow arsenic trisulfide , when it was shown to the jury it had deteriorated, allowing the suspect to be acquitted due to reasonable doubt. Annoyed by that, Marsh developed a much better test. He combined a sample containing arsenic with sulfuric acid and arsenic-free zinc , resulting in arsine gas. The gas
1530-504: Is a statement against interest . 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
1615-597: Is a common technique used in the field of Forensic Science. Chromatography is a method of separating the components of a mixture from a mobile phase. Chromatography is an essential tool used in forensic science, helping analysts identify and compare trace amounts of samples including ignitable liquids, drugs, and biological samples. Many laboratories utilize gas chromatography / mass spectrometry (GC/MS) to examine these kinds of samples; this analysis provides rapid and reliant data to identify samples in question. A method for detecting arsenious oxide, simple arsenic , in corpses
1700-413: 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
1785-505: Is attributed to the book of Xi Yuan Lu (translated as Washing Away of Wrongs ), written in China in 1248 by Song Ci ( 宋慈 , 1186–1249), a director of justice, jail and supervision, during the Song dynasty . Song Ci introduced regulations concerning autopsy reports to court, how to protect the evidence in the examining process, and explained why forensic workers must demonstrate impartiality to

He was called by the prosecution in a murder trial to give evidence as a chemist in 1832. The defendant, John Bodle, was accused of poisoning his grandfather with arsenic-laced coffee. Marsh performed the standard test by mixing
1955-507: Is derived directly from English decisions and legal principles. There are some differences including the Charter of Rights and Freedoms that give an accused person more rights. The crown must prove beyond a reasonable doubt that the accused confessed voluntarily or the confession will be excluded from evidence by the judge. The legal term voluntary has a different meaning than the everyday meaning of voluntary. The crown will be looking to prove

It is a broad field utilizing numerous practices such as the analysis of DNA , fingerprints , bloodstain patterns , firearms , ballistics , toxicology , microscopy and fire debris analysis. Forensic scientists collect, preserve, and analyze evidence during the course of an investigation. While some forensic scientists travel to

The paper highlights two recent European courses as exemplars of educational endeavors, elucidating lessons learned and proposing future directions. The overarching conclusion is that the heightened focus on forensic intelligence has

In the case of trained interviewers, many interrogation teams are practiced in the " Reid technique ", which identifies behavioral cues common for a guilty suspect including slouching, fidgeting, and avoiding eye contact. These cues have not been empirically validated to demonstrate deception in scientific studies. In terms of
2295-513: Is thought that these tests had some validity since a guilty person would produce less saliva and thus have a drier mouth; the accused would be considered guilty if rice was sticking to their mouths in abundance or if their tongues were severely burned due to lack of shielding from saliva. Initial glance, forensic intelligence may appear as a nascent facet of forensic science facilitated by advancements in information technologies such as computers, databases, and data-flow management software. However,
2380-443: Is used to test theories conceived by the police, for example, or by the investigator himself. All of the techniques advocated by Holmes later became reality, but were generally in their infancy at the time Conan Doyle was writing. In many of his reported cases, Holmes frequently complains of the way the crime scene has been contaminated by others, especially by the police, emphasising the critical importance of maintaining its integrity,
2465-542: The Bertillon system and a fingerprint advocate at Police Headquarters, introduced the fingerprinting of criminals to the United States. The Uhlenhuth test , or the antigen–antibody precipitin test for species, was invented by Paul Uhlenhuth in 1901 and could distinguish human blood from animal blood, based on the discovery that the blood of different species had one or more characteristic proteins. The test represented
2550-450: The Police and Criminal Evidence Act 1984 . Following a representation by the defendant or upon the court's own motion, evidence tendered by a co-defendant of a defendant's confession must not be admitted unless the co-defendant proves on the balance of probabilities that it was not obtained: The common law rules on the admission of confessions are preserved, and apply so long as the statement

2720-602: The ad hoc methods used to identify captured criminals in France in the 1870s, he began his work on developing a reliable system of anthropometrics for human classification. Bertillon created many other forensics techniques, including forensic document examination , the use of galvanoplastic compounds to preserve footprints , ballistics , and the dynamometer , used to determine the degree of force used in breaking and entering . Although his central methods were soon to be supplanted by fingerprinting , "his other contributions like
2805-516: The mug shot and the systematization of crime-scene photography remain in place to this day." Sir William Herschel was one of the first to advocate the use of fingerprinting in the identification of criminal suspects. While working for the Indian Civil Service , he began to use thumbprints on documents as a security measure to prevent the then-rampant repudiation of signatures in 1858. In 1877 at Hooghly (near Kolkata), Herschel instituted
2890-495: The occult largely ceased to influence the court's decisions. Two examples of English forensic science in individual legal proceedings demonstrate the increasing use of logic and procedure in criminal investigations at the time. In 1784, in Lancaster , John Toms was tried and convicted for murdering Edward Culshaw with a pistol . When the dead body of Culshaw was examined, a pistol wad (crushed paper used to secure powder and balls in
2975-500: The prosecution or the defense. While any field could technically be forensic , certain sections have developed over time to encompass the majority of forensically related cases. The term forensic stems from the Latin word, forēnsis (3rd declension, adjective), meaning "of a forum, place of assembly". The history of the term originates in Roman times, when a criminal charge meant presenting
3060-411: The state television . Notable victims includes Wang Yu , a female human rights lawyer, and Swedish NGO worker Peter Dahlin , and Gui Minhai , a Chinese-born Swedish book publisher. Confession evidence can be considered, arguably, the best piece of evidence of guilt in the criminal justice system. However, false confessions do occur, therefore there must be some flaws in the interrogation process. In
3145-630: The 20th century, notably the Universal Declaration of Human Rights , which greatly reduced the legal acceptance of forced confessions, these are still practised and accepted in some jurisdictions. The People's Republic of China has been shown to systematically employ forced televised confession, often in an extrajudicial context, against Chinese dissidents and workers of various human rights group in an attempt to discredit, smear and suppress dissident voices and activism. Scripted confessions, obtained via systematic duress and torture, are broadcast on

As the rational values of the Enlightenment era increasingly permeated society in the 18th century, criminal investigation became a more evidence-based, rational procedure − the use of torture to force confessions was curtailed, and belief in witchcraft and other powers of
3315-484: The Miranda warning, it has been found that innocent suspects are more likely to waive their rights than those who are guilty, so therefore Miranda rights in most cases do not protect accused innocents from interrogation (article 1). Through the use of minimization, when an investigator justifies the crime with possible excuses to make it easier to confess to, and the use of the false evidence ploy, mentioning evidence that proves
3400-527: The absence of threats, direct or veiled, by the police. Threats will almost certainly render the confession involuntary. This can include threats to arrest or interrogate other persons close to the accused. Promises or inducements made in the form of a quid pro quo (like a confession in exchange for ignoring a more serious charge) will also often result in an inadmissible confession. Generally, police are allowed to lie by claiming to claim to have evidence, like DNA evidence that does not exist. If police lies cause
3485-465: The book on forensics stating that all wounds or dead bodies should be examined, not avoided. The book became the first form of literature to help determine the cause of death. In one of Song Ci's accounts ( Washing Away of Wrongs ), the case of a person murdered with a sickle was solved by an investigator who instructed each suspect to bring his sickle to one location. (He realized it was a sickle by testing various blades on an animal carcass and comparing

The case would be decided in favor of the individual with the best argument and delivery. This origin is the source of the two modern usages of the word forensic —as a form of legal evidence; and as a category of public presentation. In modern use,
3740-480: The cause and manner of death . Ambroise Paré , a French army surgeon , systematically studied the effects of violent death on internal organs. Two Italian surgeons, Fortunato Fidelis and Paolo Zacchia, laid the foundation of modern pathology by studying changes that occurred in the structure of the body as the result of disease. In the late 18th century, writings on these topics began to appear. These included A Treatise on Forensic Medicine and Public Health by

Haque and Bose were Indian fingerprint experts who have been credited with the primary development of a fingerprint classification system eventually named after their supervisor, Sir Edward Richard Henry . The Henry Classification System , co-devised by Haque and Bose,
3910-404: The confession is reliable. On the other hand, even without torture, various cases of averred false confessions demonstrate that, in itself, one person's confession is not a sufficient proof. False memory (including memory biases , etc.) or privileges granted under plea bargaining might lead to such false confessions. A forced or coerced confession is a confession obtained from a suspect or
3995-467: The confession. However, many miscarriages of justice in Japan are due to police forcing a false confession. On one hand, confessions obtained under torture have often been considered to be not objective enough, since the use of such means may lead to the suspect in confessing anything. However, when the confession reveals secrets only known to the perpetrator (such as the location of the body or murder weapon),

When it was compared with Rojas' prints, it was found to be identical with her right thumb. She then confessed to the murder of her sons. A Fingerprint Bureau was established in Calcutta ( Kolkata ), India, in 1897, after the Council of the Governor General approved a committee report that fingerprints should be used for
4165-537: The criminal justice system, as well as policing and intelligence missions, underscore the necessity for the establishment of educational and training initiatives in the field of forensic intelligence. This article contends that a discernible gap exists between the perceived and actual comprehension of forensic intelligence among law enforcement and forensic science managers, positing that this asymmetry can be rectified only through educational interventions The primary challenge in forensic intelligence education and training
4250-442: The criminal justice system. Instead, it urges a perspective that views forensic science as a discipline studying the informative potential of traces—remnants of criminal activity. Embracing this transformative shift poses a significant challenge for education, necessitating a shift in learners' mindset to accept concepts and methodologies in forensic intelligence. Recent calls advocating for the integration of forensic scientists into
4335-437: The dates of the murders did not coincide with a single boat's movements, and the transfer of a crewman between boats was also ruled out. At the end of October, Robert Anderson asked police surgeon Thomas Bond to give his opinion on the extent of the murderer's surgical skill and knowledge. The opinion offered by Bond on the character of the "Whitechapel murderer" is the earliest surviving offender profile . Bond's assessment

In that same year, Francisca Rojas of Necochea was found in a house with neck injuries whilst her two sons were found dead with their throats cut. Rojas accused a neighbour, but despite brutal interrogation, this neighbour would not confess to
4505-502: The first person to be exonerated using DNA. Jefferys confirmed that the DNA profiles were identical for the two murder semen samples. To find the perpetrator, DNA samples from the entire male population, more than 4,000 aged from 17 to 34, of the town were collected. They all were compared to semen samples from the crime. A friend of Colin Pitchfork was heard saying that he had given his sample to
4590-574: The manner of the mutilations. The alibis of local butchers and slaughterers were investigated, with the result that they were eliminated from the inquiry. Some contemporary figures thought the pattern of the murders indicated that the culprit was a butcher or cattle drover on one of the cattle boats that plied between London and mainland Europe. Whitechapel was close to the London Docks , and usually such boats docked on Thursday or Friday and departed on Saturday or Sunday. The cattle boats were examined, but

If so, (2) is that matter of sufficient relevance to justify its introduction in evidence? If so, (3) would the admission of the evidence have such an adverse effect on the fairness of the proceedings that the judge ought not to admit it? Canadian common law on confessions

In Warwick 1816, a farm laborer was tried and convicted of the murder of a young maidservant. She had been drowned in a shallow pool and bore the marks of violent assault. The police found footprints and an impression from corduroy cloth with a sewn patch in the damp earth near

This Institute was followed by many similar institutes all over the world. In 1909, Archibald Reiss founded the Institut de police scientifique of the University of Lausanne (UNIL) , the first school of forensic science in
4930-571: The newfound prestige of forensics and the use of reasoning in detective work was the popularity of the fictional character Sherlock Holmes , written by Arthur Conan Doyle in the late 19th century. He remains a great inspiration for forensic science, especially for the way his acute study of a crime scene yielded small clues as to the precise sequence of events. He made great use of trace evidence such as shoe and tire impressions, as well as fingerprints, ballistics and handwriting analysis , now known as questioned document examination . Such evidence
5015-429: The patterns left on bullets and cartridge casings after being ejected from a weapon. When fired, a bullet is left with indentations and markings that are unique to the barrel and firing pin of the firearm that ejected the bullet. This examination can help scientists identify possible makes and models of weapons connected to a crime. Henry Goddard at Scotland Yard pioneered the use of bullet comparison in 1835. He noticed
5100-493: The police claiming to be Colin. Colin Pitchfork was arrested in 1987 and it was found that his DNA profile matched the semen samples from the murder. Because of this case, DNA databases were developed. There is the national (FBI) and international databases as well as the European countries (ENFSI: European Network of Forensic Science Institutes). These searchable databases are used to match crime scene DNA profiles to those already in

A novel educational challenge is articulated for forensic science university programs worldwide: a shift in emphasis from a fragmented criminal trace analysis to a more comprehensive security problem-solving approach. In 16th-century Europe, medical practitioners in army and university settings began to gather information on

Others are involved in analysis of financial, banking, or other numerical data for use in financial crime investigation, and can be employed as consultants from private firms, academia, or as government employees. In addition to their laboratory role, forensic scientists testify as expert witnesses in both criminal and civil cases and can work for either
5780-405: The suspect guilty (which actually does not exist), many innocent people end up confessing to crimes they have not committed. Most people cannot recognize a false confession, because confessions are trusted and a jury or judge would see confessing to a crime in which the suspect did not commit as something against self-interest, which in most people's minds does not make sense. In terms of how harmless

This was reaffirmed on 5 May 2010 by the Supreme Court of India in
5950-770: The term forensics is often used in place of "forensic science." The word " science ", is derived from the Latin word for 'knowledge' and is today closely tied to the scientific method , a systematic way of acquiring knowledge. Taken together, forensic science means the use of scientific methods and processes for crime solving. The ancient world lacked standardized forensic practices, which enabled criminals to escape punishment. Criminal investigations and trials relied heavily on forced confessions and witness testimony . However, ancient sources do contain several accounts of techniques that foreshadow concepts in forensic science developed centuries later. The first written account of using medicine and entomology to solve criminal cases

In ancient India, some suspects were made to fill their mouths with dried rice and spit it back out. Similarly, in ancient China , those accused of a crime would have rice powder placed in their mouths. In ancient middle-eastern cultures, the accused were made to lick hot metal rods briefly. It

The book also described how to distinguish between a drowning (water in the lungs ) and strangulation (broken neck cartilage ), and described evidence from examining corpses to determine if a death was caused by murder, suicide or accident. Methods from around

In his opinion the killer must have been a man of solitary habits, subject to "periodical attacks of homicidal and erotic mania ", with the character of the mutilations possibly indicating " satyriasis ". Bond also stated that "the homicidal impulse may have developed from

Over 2000 people were interviewed, "upwards of 300" people were investigated, and 80 people were detained. The investigation was initially conducted by the Criminal Investigation Department (CID), headed by Detective Inspector Edmund Reid . Later, Detective Inspectors Frederick Abberline , Henry Moore , and Walter Andrews were sent from Central Office at Scotland Yard to assist. Initially, butchers, surgeons and physicians were suspected because of
