DNA profiling

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…

more reliably analyse DNA from crime scenes and use this information to find and detain suspects. Through composing a detailed portfolio of an individual’s DNA there would be no question in determining if the suspect was present at the crime scene. Function – This innovation served the function of locating similarities in the DNA of relatives to help in early detection of genetic diseases. It also helps to…

Criminal Profiling: More than Movie Magic Aspects like age, marital status, ethnicity, and identifying characteristics are what define a typical criminal profile and are crucial in catching serial criminals. Criminal Profiling has made a debut in the media with shows like Criminal Minds and novels like Sherlock Holmes, but the science behind profiling is often left to the imagination to create the idea of a profiler as a magical and all-knowing being, when in reality they are highly trained…

science to law by analyzing DNA for legal evidence. DNA profiling is the predominant application and forensic science, DNA profiling allows us to take more than one sample of an unknown DNA specimen and determine if it has the same genetic match. Moreover, DNA profiling is to help determine and solve crime scenes such as murders, assaults, and rapes. The technique used for analyzing DNA is restriction fragment length polymorphism testing. It restricts the enzyme, which cuts DNA at specific…

As stated previously, Douglas and Ressler interviewed serial murderers to develop theories and categories of different types of offenders. Most notably, though, is their idea of the organized versus disorganized offender that the main theory of profiling is based on. According to Douglas and Ressler, organized crimes are committed by those who show no remorse and have carefully planned their every move, which is why little evidence is found at the crime scene. In contrast, disorganized crimes…

According to Kitaeff (2011), some things that play a role in scientific model of criminal profiling include the following: • Signature - Does the suspect do something each time that reveals something about them. For example if they leave a bible, or place a blanket over the victim. • Modus Operandi - Pattern to the crime such as the victim always…

The National Institute of Justice’s article “Extending Time to Collect DNA in Sexual Assault Cases” explains the use and shortcomings of DNA profiling in identifying a suspect in a sexual assault case. DNA profiles require the use of short sequences that repeat a number of times, called short tandem repeats (STRs). With the current DNA profiling method, many jurisdictions protocols require to collect the samples within three days of the sexual assault. However, a viable analysis is still…

wonder if DNA is the most effect way to catching a criminal (Steen). Without the use of it there would not be the freeing or those accused of a crime and proving of their innocence. In today’s society the use of deoxyribonucleic acid, known as DNA; is the basic building block of life and has aided in identifying criminals and solving major crimes (Houck and Siegel). But on the other hand DNA has also proven many individuals to be innocent of a crime. The information that inside of one’s DNA set…

According to the article “DNA Technology and Crime” “In 1992 lawyers Barry Scheck and Peter Neufeld created the Innocence Project, a legal organization aimed at overturning wrongful conviction through DNA profiling. Since then, more than two hundred criminal convictions have been overturned in the United States alone.” The Innocence Project is needed to help turn over wrongful convictions that were made. The article “DNA Technology and Crime” stated in their article “ DNA was first studied in…

Biological Evidence DNA can be transferred to evidence directly or indirectly. This exchange of information between objects is based on the Locard Exchange Principle. The Locard Exchange Principle states that information is exchanged whenever two items come into contact with each other (Houck and Siegel 54). The direct transfer of DNA can be described as DNA that is “transferred from a source to a location with no intermediaries” (Houck and Siegel 55). The indirect transfer of DNA “involves one…
