It's 3AM. You are on call for the Violent Crimes Response Unit. You arrive on the scene of a missing person case. No one has seen the home owner in about a week and the Homicide Sergeant has asked you to examine the home for anything indicating that a crime may have occurred. You walk into the bathroom and smell the strong odor of bleach. Someone did some heavy cleaning in here recently. But they missed a spot. On the mirror of the bathroom, you see a faint, light brown streak. It could be dried blood. What

o Wipe - bloodstains caused by an object being moved across a preexisting bloodstain.
BPA professionals can also determine where certain bloodstains came from. For example, if a spatter stain is located on a vertical surface, a BPA expert can measure that stain and use a scientific formula to determine where in the room the blood was first put into motion. Thus, they can determine where a victim or suspect was standing, kneeling, or lying when they were injured.

Real World Example: In 1985, Graham Backhouse was accused and convicted of trying to murder his wife with a car bomb, framing his neighbor for it, and then killing his neighbor. While a large amount of forensic evidence was used in this case, one piece of the case file involved BPA. Backhouse claimed that he had a violent struggle with his neighbor, which resulted in him being stabbed and cut. Examiners noted that the bloodstains on the kitchen floor, where this alleged attack occurred, were actually blood drops, made by a wound that would be consistent with cutting one's own
Bloodstain pattern analysis (BPA) is one of many specialties in the field of forensic science; the science of bloodstain pattern analysis use scientific knowledge from other fields to solve problems. BPA also uses the scientific method to examine bloodstain evidence at a crime scene where blood is present by gathering information, observing, documenting, analyzing, evaluating, and technical or peer reviewing. A bloodstain pattern analysis job is to collect, categorize and interpret the shape and distribution of bloodstains within a crime scene (Peschel, 2011). Bloodstain patterns can reconstruct a crime scene and then determine the crime as an accident, homicide, or suicide; the blood can also identify the location, quality and intensity of an external force. The purpose of a BPA’s is to determine bloodstain patterns and to recreate the action that caused the blood.

A forensic evaluation is a comprehensive and elaborate process that incorporates collection, analysis, and integration of information form multiple sources. Child welfare related evaluations are one of the most complex types of forensic evaluations requiring expert opinion and recommendations on matters pertaining to child custody and visitation, parental fitness and termination of parental rights, and evaluation of adoptive and foster parents. The primary purpose of these evaluations is to inform the court and facilitate decision-making process in child welfare cases. During a child custody evaluation the main doctrine to uphold is the “best interest of the child.” The safety of the child is of paramount consideration. This along with well-being
Forensic Psychology is a specialized practice by psychologists in areas of clinical psychology, counseling psychology, school psychology, and neuropsychology. You will be engaged regularly as an expert and primarily proposed to offer professional psychological expertise to the judicial system.
Overall, though, I believe that Stein is the closest scholar here-mentioned to have accounted for the explanation behind these controversies. The main mistake made by many modern scholars lies in the planning and the research – too much effort is spent on seeking to explain this opposition between the Proculians and the Sabinians in terms of two internally coherent law schools which differ entirely and have held controversies stemming from a specific occurrence. I have personally, as a student of the Roman law, found it difficult in reading the sources and differing theories from scholars to do just this – because, as Scarano Ussani stated, nowhere, in the mass of research that has been done, have any definitive results been reached. As afore-mentioned, I ruled out the political explanation for the purpose of answering this question, and the social explanation does not add a great deal to the debate for me. The theories supporting the social standpoint as addressed in this essay are among the worst for choosing to ignore many of the hard facts in order to make their theory fit better. This leaves only the philosophical and methodological explanations. The philosophical explanation is a reasonably sound one, although as explored above, I do believe that its significance has been largely exaggerated. There is no doubt over the fact that philosophy has played an influential role - even if you only look at Gaius’ ius gentium which contains a certain level of Stoic influence, but as mentioned above there are major differences which have been overlooked slightly in those arguments. The methodological explanation is another seemingly logical one, and the most reliable of all theorems explored in this essay, in my opinion, as it i...
In order to understand how to compile evidence for criminal cases, we must understand the most effective types of evidence. This topic is interesting because there are ample amounts of cases where defendants have gotten off because of the lack of forensic evidence. If we believe forensic evidence is so important and it affects our decisions, then maybe we need to be educated on the reality of forensic evidence. If we can be educated, then we may have a more successful justice system. If we have a more successful justice system than the public could gain more confidence that justice will be served. In order to do this, we must find what type of evidence is most effective, this can be done by examining different types of evidence.
Forensic Science, recognized as Forensics, is the solicitation of science to law to understand evidences for crime investigation. Forensic scientists are investigators that collect evidences at the crime scene and analyse it uses technology to reveal scientific evidence in a range of fields. Physical evidence are included things that can be seen, whether with the naked eye or through the use of magnification or other analytical tools. Some of this evidence is categorized as impression evidence2.In this report I’ll determine the areas of forensic science that are relevant to particular investigation and setting out in what method the forensic science procedures I have recognized that would be useful for the particular crime scene.
Forensic evidence can provide just outcomes in criminal matters. However, it is not yet an exact science as it can be flawed. It can be misrepresented through the reliability of the evidence, through nonstandard guidelines, and through public perception. Forensic science can be dangerously faulty without focus on the ‘science’ aspect. It can at times be just matching patterns based on an individual’s interpretations. This can lead to a miscarriage of justice and forever alter a person’s life due to a perceived “grey area” (Merritt C, 2010) resulting in a loss of confidence in the reliability of forensic evidence.
Use of Forensic Science in Cuban Criminal Justice I have always wanted to travel to Cuba because I love the culture and wanted to know more. I have always heard that the doctors in Cuba are some of the best in the world and recently the Cuban scientists have developed a new technique used in forensic science and, since forensic science is my mayor, I am interested in learning more about forensic science in Cuba. I am studying Cuba to know why forensic science has become such a large importance within the Cuban criminal justice system and why Cuban forensic scientists are leading internationally in the forensic science field.
As far back as 1832, James Marsh was the first to use forensics at trial to give evidence as a chemist in 1832. Since that time forensic science and evidence has come a long way in various ways and technology to help in determine if the suspect is guilt or not, through such things as DNA testing, blood, and fingerprints. The first forensic police crime lab was created in 1910. The contributions of Dr. Edmond Locard, a French scientist and criminologist, proposed that “everything leaves a trace”. This principle is still valid today as it was so many years ago. No matter how small, the specialized trained technicians and investigators can take these methods and go to a crime scene to get evidence. “Forensic science is the application of sciences such as physics, chemistry, biology, computer science and engineering to matters of law.” (Office of Justice, 2017) These different sciences can help achieve and assist in solving a case. Forensic science has also the ability to prove that a crime was committed, it can find the elements of the crime, it can help place the suspect at the scene and whether the suspect had any contact with the victim. However, in the last several years the techniques and with the use of technology the evidence that forensic science uncovers can also exonerate an innocent individual who has been falsely accused of the
According to the American academy of forensic science, the forensic sciences form a vital part if the entire justice and regulatory system. Forensic science is an enticing career having to do with science and criminal justice, a large variety of schooling is needed to start this job Despite the fact that it can be a dangerous environment it can be an exciting profession to pursue. There are many different fields in forensic science that you can study or major in but they all have the same objectives.
We do have known what forensics is. Forensics that we know is an application of various sciences to answer questions that are important to legal system in which it may be related to a crime. Forensics generallu covering something or methods of a scientific nature and also the rules established from the facts of the event, to do an introduction to physical evidence. This is just a usual forensics. Nowadays, forensics is not just like that, digital devices are everywhere today, helping people to communicate with other people globally, not just between town. We can use that to do some forensics thing too, and find the evidence. It is called Digital Forensics.

“The word ‘forensics’ means “connected with the courtroom”; so forensic science is, therefore, concerned with gathering hard evidence that can be presented in a trial” (Innes 9). Forensic science is a science that is applied specifically to legal matters, whether criminal or civil. “Few areas in the realm of science are as widespread and important as forensic science” (Hunter 12). Forensics is the one science that is most commonly used in everyday life. It is also a branch of science that incorporates other branches of science such as biology, chemistry, and etc. Since it is used almost every day “No one can dispute the importance of the contributions to society made by forensic science; the ability to solve crime is undeniably important” (Hunter 13). Forensic science has given criminal investigation a new edge. “Advances in science have opened the door for more effective evidence discovery, howev...
Forensic science includes all types of different science such as: physics, chemistry, biology, computer science and engineering to matter of law. A forensic scientist is a specialist in a field of science who applies their knowledge to the purposes of law. The job as a Forensic Scientist not only has many details and facts you have to remember but you also need items of evidence that are relevant in order to examine the scene correctly.
