Evidence Integrity And Evidence Continuity Essay

Why is it important to secure the crime scene? What do you think would be the most difficult part of doing this?

Forensic science is defined as the practice of utilizing scientific methodologies to clarify judicial inquiries. The field of forensic science contains a broad range of disciplines and has become a vital aspect of criminal investigations. Some forensic disciplines are laboratory-based; while others are based on an analyst’s interpretation of observable patterns (Kourtsounis, 2009). According to the Innocence project’s website; in greater than fifty percent of wrongful convictions, the use of invalidated or improper forensic techniques played a role in cases; which were later

It’s important that all evidence is identified so that forensic scientist can examine it and take

The popular television show, CSI: Crime Scene Investigations has been on the air for 12 years, and it has brought forth the behind-the-scenes actions of criminal investigations, even if its portrayals are not always scientifically accurate. This has caused an interest in the forensic sciences that has led most people to a skewed view of how a criminal investigation actually works. The reality of a criminal investigation is that it is generally more tedious and difficult than the theory of criminal investigation would have you believe. By examining the forensic and investigative procedures of the case of Pamela Foddrill, it is apparent that the theory of criminal investigation was not representative of the procedures concerning examination

Tashanna N Garcia is currently enrolled in the Masters of Criminal Justice, with a concentration in Forensic Science, program at Saint Leo University. Tashanna comes from a military background where she served as an officer in the United States Marine Corps. Her military training was essential to her transition into law enforcement, where she spent the last ten years working for two police departments as a patrol officer and then for the Alabama Department of Public Safety as a Traffic Homicide Investigator for the State Troopers. Tashanna hopes to return to the law enforcement field in an administrative capacity and has a passion for forensic disciplines. Correspondence concerning this paper should be addressed to Tashanna N Garcia,

The Louisiana State Police Crime Laboratory was developed to provide the highest quality of professional forensic services to the State of Louisiana. The commitment of the agency includes applying sound scientific principles in all analyses, being responsive to our customers, conducting our operations in a fair and objective manner, and being a leader in advancing forensic science. The mission of the laboratory is to assist all of the local, state, and federal law enforcement agencies in Louisiana in the investigation of criminal activity (Office of Public Safety Services, 2015). The agency is also committed to providing accurate and timely scientific analysis of items of physical evidence and reporting the results of those analyses to appropriate entities in the criminal justice community.

Forensic science can be defined as the relationship between law and science; it answers the questions of how, why and who committed the crime, with the input of multiple actors. However, there are currently problems with

In this position paper I have chosen Bloodsworth v. State ~ 76 Md.App. 23, 543 A.2d 382 case to discuss on whether or not the forensic evidence that was submitted for this case should have been admissible or not. To understand whether or not the evidence should be admissible or not we first have to know what the case is about.

Throughout my educational journey, my interest and attention was always captivated by classes which had even the slightest tendency towards Forensic Psychology. Yet, my passion remained unconscious until I took a class of Criminal Law in Business, class which seemed to hold the answer for the consuming question “What am I going to study at University?” From there, I began putting the puzzle pieces together, determined to find the source of the spark- Law, Criminology, Forensic Science all seemed to bring me closer to the right one for me: Forensic Psychology. Reading the first few lines of the field description was enough to assure me that there is no other subject could fascinate, intrigue and motivate me to give by best to apart from this. I became infatuated with the evidence that evil in a human being can be so incandescent, transparent and mischievous that it could bring down any barrier of normality. I became absorbed by its power to grow into the mind and punish the

Forensic evidence has been shown to be reliable due to many factors of evidence such as DNA, blood, fingerprints, etc.; however, many cases have shown that

May and Powles view evidence as ‘something’ which tends to prove or disprove something else. In the context of a trial this consists of information placed before the court for the purpose of proving or disproving facts in issue. Beecher-Monas states that in a system based on the rule of law and which aspires to ‘truth’, the accuracy and reliability of such information is essential. The mechanisms available to the court to determine the latter, centre on the presentation of evidence under oath, cross-examination and the observation of witness demeanour .

Criminal Forensics solves murders or death and brings comfort to families. Criminal Forensics is needed throughout the world. It answers the question, “What happened?” The most important part of criminal forensics is when the murder or case gets solved. The reason that this is the most important part is because this is what the case is about. The case is about figuring out what happened to the person, and if they were murdered, it is about getting someone in handcuffs. These people need justice and if it not given then who will give it. Criminal forensics is the key part in solving any case. It brings comfort to families who desperately need it. Most importantly it answers the question,

There are many tangible circumstances that tend to prove or disprove some facts in all criminal or civil cases. Under rule 41(b) “A warrant may be issued under this rule to search for and seize any (1) property that constitutes evidence of the commission of a criminal offenses; or (2) contraband, the fruits of a crime, or things otherwise criminally possessed; or (3) property designed or intended for use or which is or has been used as the means of committing a criminal offense; or (4) person for whose arrest there is probable cause, or who is unlawfully restrained” (John N. Ferdico, 1999). Evidence is one of the single most important pieces of a criminal trial. It is used to determine a defendant’s guilt or innocence.

Today, more than ever, the quality of evidence in criminal cases is scrutinized because of contamination. Contamination is the introduction of something that physically corrupts a substance at a crime scene that was not previously there; it comes in many forms and most often times comes from the humans who investigate a crime scene. It is imperative that prevention of cross-contamination is implemented when gathering evidence. Several of the more sensitive forensic techniques such as trace analysis, bloodspatter interpretation, and DNA comparison are not being used to their fullest potential. Items of physical crime scene evidence are not always visible to the naked eye and may be easily overlooked so deliberate and methodical approach to collection and preservation of evidence is essential. Prosecutors have lost cases due to crime scene contamination; this could be prevented by simple and productive behaviors. The U.S. Supreme Court, in a leading case on physical evidence, stated:

Forensic science involves the use of science to solve criminal and civil crimes but mostly lies on the side of criminal investigations. It makes it possible to identify the criminals based on the DNA traces they leave behind. It involves analyses of blood, DNA and other evidences and later on uses the findings as evidence in the court of law. It helps in solving the various crimes in the world and this has been the greatest contributor to the growth of the sector. Cases that were previously considered impossible due to lack of evidenced tracing to the victim can now be solved using forensic science evidences. The essay aims at analyzing the different aspects of forensic science that are used in the process of solving criminal activities. It will also look at the different cases that forensic science was used to solve crimes in a court of law.
