Forensic profiling

Discussion Bennel’s study examines the effective use of offender profiles during a criminal case. There is strong criticism toward the use of profiling in the justice system because of the ambiguity that surrounds many of the statements made by experts in profiling. Multiple personality traits made up of vague statements are frequently taken into perspective as part of these outlined criminal behaviours. The aforementioned ambiguity creates doubt in what may constitute an aspect of the…

Psychological profiling has had a long history within the criminal justice field including the FBI. Many believe that this type of profiling has no usefulness in solving crimes, however the more that is learned about how a criminal thinks the better equipped to solve crimes sooner and prevent new crimes. Psychological profiling can be used to limit the amount of suspects for a given crime. While a psychological profile will help to solve a crime, having a solid crime scene examination is a…

Criminal profiling is hands down one of the most beneficial forms of offender identification tools that law enforcement has at their disposal. Education on the different forms of criminal profiling is important for both the general public as well as law enforcement. Further, proper use of criminal profiling is a leading method by which law enforcement can reduce recidivism. Knowledge on how each type of profiling is conducted is important because misuse or a misguided procedure for…

Before the 19th century, witness testimonies were viewed as the ‘smoking gun’ during court proceedings. In the 1930s, French criminologist and forensics pioneer Dr. Edmond Locard outlined his theory of exchange in the American Journal of Police Science (Solanki, 2013). Locard’s exchange principle was derived from the concept that if one makes contact with another person, place or thing, physical materials are inevitably exchanged. Therefore, when applied to a crime scene, a criminal cannot…

Otto Schneider Grade 10 Biology Ms Ruebe D Assessment - DNA Technology DNA Profiling Forensic Identification Forensic Identification refers to the use of forensic science to identify objects from trace evidence found on them. Trace evidence is used to reconstruct crimes or accidents. DNA profiling is a method in forensic science which can identify individuals by their DNA profiles. DNA profiles are encrypted sets of letters that represent a person’s DNA makeup. These sets can be used as a…

Intro The technique of DNA profiling was first discovered in 1985 by Sir Alec Jefferys, a Leicester University geneticist. The work that he did in the laboratory led to the discovery of the technique for genetic profiling, which revealed a pioneer method of biological identification. A humans DNA can be found in hair, saliva, blood, and other various human properties. Sir Alec Jeffreys knew that what he had done was going to be revolutionary. After his discovery, he said “My life changed on…

of blood. Hence, the use of DNA as a tool for forensic investigation cannot be overstated as almost all the cells in the body are haploid, excluding gametes. Additionally, several types of biological material are useable in forensic science for DNA analysis and…

In the dead of night, a blood-curdling cry for help could be heard from several blocks away; however, no one is around to hear. A woman runs frantically for her life. She runs this way and that but fails to realize that she is trapped in a maze of houses and alleyways . She yells for help, but like the last time, no one comes to rescue her. The realization hits her as she finds herself trapped between the wall and her killer. Terrified, she turns to face her end. Just as she does, a shot rings…

Today, DNA profiling is well used all over the world. DNA profiling was developed by the geneticist of the Leicester University in 1985. DNA profiling is the process where a specific DNA pattern, called a profile, is obtained from a person or sample of bodily tissue (“DNA profiling Biotech Learning Hub”). By learning DNA profiling, it enable us to identify individuals. It is really common to use DNA profiling now and a lot of people starts to use the technology. While supporters of using DNA…

Forensic DNA is the process of using and collecting DNA from crime scenes to solve criminal investigations and to ensure accuracy and fairness in the Criminal Justice System. DNA profiling has grown significantly in the past years and has been extremely useful in identifying suspects, criminals and other people involved in the crime. If the suspect is unidentifiable, DNA evidence is compared to a DNA database to identify the criminal. DNA testing has both advantages and disadvantages many of…
