Forensic Sciences: Biotechnology Strategies And Methods

Their job is to find out if someone had poisons or drugs in their system by testing the blood of the person and eventually test other organs for the presence of drugs or poisons. They also need to calculate the total amount of drugs or poisons in the person system and understand how this could have affected them. After they need to write down a report that could be used in court with the forensic toxicologist being present as an expert witness. Describe the roles and responsibilities of a DNA lab

Now psychological profiling which is also known as behavioral criminal personality and criminal profiling is a method that investigators use to develop a profile of a murder, rapists as well as other violent criminals who have not been caught by police officers yet for a crime they committed. On the other hand offender profiling is the belief that it may be possible to work out the characteristics of an offender by simply examining the characteristics of their offences. Therefore, the investigator would use all of the available information they have found about a crime, a crime scene or a victim to build a profile of the criminal or offender. Therefore, crime scene profiling would be when an investigator takes the physical evidence, that was collected and properly analyzed by specialists from a crime scene and systematically reconstruct the scene of the crime in order to get a strategy that will help them to capture the

Furthermore, the most important sources of crime information in U.S criminal justice system are the FBI’s Uniform Crime Reports (UCR) and the BJS’ National Crime Victimization Survey. Keywords: research methods, survey methods, sampling, types of surveys Introduction During a research exercise the data collected can be either qualitative or quantitative gathered from observations. Examples of quantitative data recorded in numerical values are survey research, field research, evaluation

A suspect with the same blood type as evidence does not make a person guilty, but if the suspect had a type O blood and the evidence was type B it clearly was not that particular suspect. These two examples are still used in cases to help persuade the guilt of a

Create rough sketch of crime scene to identify all the possible locations where evidence can be find IV. Photographic and video recording planning 1.2 Documenting the scene and evidence The state of crime scene must be properly documented in order to record the conditions of crime scene and physical evidence. There are 4 major tasks in documenting crime scene which involve note taking, photography, sketching and videography.

While a few theories are not as regular, others have developed and are utilized as a part of numerous criminal reviews today. Cutting edge criminologists consolidate the most important aspects of sociology, psychology, anthropology, and biological theories to advance their comprehension of criminal behavior. Rational choice theory, psychological, biological, and strain theory are used to analyze the

Forensic evidence is science applied to answering legal questions. Like it states in paragraph three it draws together math, physics, chemistry, biology, and anthropology to help in legal proceedings. Somethings that are example of forensic evidence are fingerprints, weapons, and bloodstains. Forensic evidence is used mostly in violent crime that go to court. Another good thing about forensic evidence is that unlike witnesses the evidence will not get confused or become frightened like it is stated

According to Andrews and Bonta (2010) the psychology of criminal conduct ( PCC) can be defined as an approach to scientifically understand the criminal behavior of individuals through a systematic approach. Additionally, the psychology of criminal conduct is considered to be interdisciplinary, and considers all aspects of science that will assist in the further comprehension of an individuals criminal behavior, and the causes of criminal behavior (Andrews and Bonta , 2010). Andrews and Bonta ( 2010) stated that the psychology of criminal conduct can be considered a subfield of criminology and psychology due to common beliefs and common interests with both disciplines. Furthermore, the psychology of criminal conduct can be described as using

Furthermore, everything should have been labeled and placed on an evidence log to ensure that it was the DNA from the actual crime scene. Although, it could have been Mr. Simpson DNA if the proper protocol had been followed they may have been able to get a guilty verdict on the double murder as well as a life sentence. I feel that given all of the fact and evidence in the case that the court did make the right decision. Unfortunately, if the evidence has been contaminated it cannot be used in court and that makes a big difference in a case. Therefore, this case showed the nation that if the evidence does not fit the crime than there is no possible way to find someone guilty of a crime because there is no physical evidence to prove that they actually committed the

DNA profiling is a method that is becoming more popular in criminal investigations because of how the method can guarantee a DNA match. Unlike other methods, DNA profiling can take a DNA sample of a suspect and give an identity, because with DNA profiling the method uses all types of records to find the identity, not just the records of past criminals. The use of all of these different records helps in case the suspect’s match is a guarantee and not just someone with a past criminal record, whose DNA is similar to that of the actual suspect (Pros and Cons). Another reason why DNA profiling is becoming more and more popular in criminal investigations is because DNA profiling can use a wide range of DNA samples. In other methods of finding a DNA match,

From Crime Control to Crime Management: DNA and Shifting Notions of Justice. " The Genetic Imaginary"The test was inconclusive for the man with whom the woman acknowledged having intercourse. In vacating May 's conviction and getting a new trial, Judge Roger Crittenden concluded the results of the tests that are of such decision, value, or force that it would probably change the result if a new trial should be made. May was released from the Kentucky State Penitentiary at Eddyville. One of the main reasons DNA analysis can be helpful to forensic scientists is that in some of the tissues, mitochondrial DNA is in excess and compared to DNA.

As we gone further along in history we can now detect DNA, DNA from dental, saliva, cameras, and facial sketches. “DNA databases have been raised using arguments from biomedical ethics; these databases are used in a complete Different context from other biomedical tools. Because they are used in the struggle against crime, the decision to create or store cannot be left by the individual. Genetic profile Instead, this decision is made by officials of society.” Annemie Patyn and Kris Dierickx Shows the pivotal role evidence has on solving crimes.

The project’s intake and evaluation staff research each case to determine whether DNA testing could be conducted to prove individuals innocence as well as guilt. When the Innocence Project started the groundbreaking use of DNA technology it allowed them to free innocent people and prove that wrongful conviction can happen in the criminal justice system. The Innocence Project’s Strategic Litigation department created in 2012, works along with the legal system and courts to acknowledge the many leading cases of wrongful convictions. The department’s three attorneys use multiple strategies to make judges, policymakers and other attorneys aware of the inaccuracy of forensic science. They also acknowledge that sometimes witness can be unreliable.

Forensic scientists and investigators can employ numerous forensic techniques to help solve this crime. These can include using biological examination in terms of detecting and identifying bloodstain pattern analysis, analyse ballistics and fingerprints. Guns are known to produce a distinct bloodstain pattern, which is the High-Velocity Impact Spatter where tiny droplets are caused by blood travelling at high speeds. By using this knowledge that investigators have about guns, they can track down and reconstruct the crime scene using biological examination.

The job I am going to discuss that is within the criminal justice system is a criminal profiler. For those who are unclear about what a career in criminal profiling entails, an author by the name of Brent Turvey evaluates the job clearly as follows, “a discipline that will necessitate the careful evaluation of physical evidence, collected and properly analyzed by a team of specialists from different areas, for the purpose of systematically reconstructing the crime scene, developing a strategy to assist in the capture of the offender, and thereafter aiding in the trial” (Fintzy, 2000, n.p.). This type of career generally requires a background in forensics and psychology. A criminal profiler is responsible for figuring out a suspect’s motivation for committing crime and creating a suspect profile. Therefore, criminal profilers are motivated to find the suspect, and also figure out why crime was committed.
