...Crime Scenes Crime scene investigation is the meeting point between science, logic and law. Processing a crime scene is and long and tedious process and is the job of crime scene investigators (CSI). CSI has the responsibilities of collecting, documenting, preserving, reconstructing and presenting evidence. It is their job to examine any physical evidence that could remotely shed any light on what happened and who is responsible. There are no typical crime scenes, evidence or investigative approaches and every crime scene should be approached in a systematic sense. According to Robert R. Ogle Jr., a crime scene search is defined as a systematic, methodical search for any physical evidence at a crime scene. When a crime has been committed, law enforcement team members use many scientific methods, along with their natural intuition and skill, to discover who is responsible. In modern crime scenes, finger and shoeprints, hair, blood, bones, and even DNA are used to help solve the puzzle and catch the criminal. Criminals find newer, cleaner, and smarter ways to kill, while the criminal investigators and forensic scientists, find newer, cleaner, and smarter ways to catch the criminal. Investigating a crime scene can take hours, sometimes days. Scene processing is the term applied to the series of steps taken to investigate a crime scene. Although the methods and techniques may differ between the experts involved, their goals are the same: to reconstruct the exact...

For instance, CSI are on call for murder scene investigations to collect and examine evidence. When CSI is contacted, their job begins. Evidence is a major part in any investigation. Without evidence, a case can grow cold quick. Anything can be evidence and when in a crime scene, everything should be treated as such. Evidence has many different categories: trace, firearm, impression, drug and alcohol, document, and biological fluids. All of these categories...

...Trace Evidence at Crime Scene Student’s Name Institutional Affiliation Trace evidence are substances established in very small amounts at the point of crime that can be analyzed and investigated to come up with viable information about the subject under investigation. Such substances may include hair, fiber, glass, glass, metal, paper, paint or botanical sources such as soil, pollen or leaves. Presence of these traces is as a result of the culprits unconsciously coming into contact with the surface (Fish & Braswell, 2011). How long such traces remain at the crime scene depends on the persistence of the substance in terms of its size and shape, amount deposited, actions between deposition and revival, scenery of environment and the amount of time passed. Irregular services tend to collect the evidence more readily than smooth surfaces. Paint can be in term of liquid, fragments, or smears. This usually identified in terms of color, type, texture, layers structure and composition. When paint dries it forms a layer that is thin and hard. It is made up of several constituents that include carriers, pigments, modifiers, extenders and binders. Carriers are the substance that becomes a solid when evaporation takes place usually an organic liquid. Pigment is the substance that gives the paint its color (Fish & Braswell, 2011). It is worth noting that blue and green pigment is usually organic compounds whereas red, yellow and white...

...Criminal Investigation: Final Essay Criminal Investigation 2530 12/3/15 Question 1 The first stage of the criminal investigation process is crime detection. First responding officers must take notes, watch persons leaving/entering crime scene area, scan, assess and reassess for officer’s safety. Officers need to address medical care issue to the people that need it. They must control, identify, and secure initial interviews. They must establish crime scene boundaries. Officers must identify and preserve crime scene evidence like the groceries, handwritten note, phone, bloody shoe print, shoe print in the dirt, fingerprints on the woman, gun bullet, and fingerprints on the purse like in the sample crime scene. Officers would most likely be doing different things at different crimes scenes. They must notify and brief investigators on what happened; and they must review and prepare final documentation. The second stage of the criminal investigation process is the preliminary investigation. Investigators need to: establish a division of labor, obtain information from first responders, interview key individuals like witnesses, conduct a reassessment of the crime scene, canvass the crime scene area, examine the crime scene and process the crime scene. Investigators must also photograph the crime scene, sketch the crime scene, measure the crime scene, search the crime scene, and do a final walk through and release the crime scene for evidence pertaining to the crime scene...

...combination of physical sciences and analytical rigor which lies at its core. Beginning with questions of technical and physical science, the project will examine the manner in which blood spatter analysis is increasingly capable of understanding how human usage of different weapons impacts the static nature of a given crime scene. Moving to questions of interpretation, the project will touch upon the manner in which information technology is improving the rigor and caliber of analysis, and thus leading to greater continuity and replicability in blood spatter analysis. Concluding, it will examine the manner in which the court system is now viewing blood spatter analysis with greater heft because of these developments. Blood Spatter Analysis and Science Beginning with questions of science, the work of Randall (2009) demonstrates how even the most esoteric of weapons can be analyzed using blood-spatter analysis. Focusing on the chain saw and its use as either a murder weapon or tool of dismemberment, Randall (2009) makes it evident that the manner in which the user interacts with the chain saw can have dramatic implications for spatter pattern, and for ultimate crime scene reconstruction. On this basis, this piece of work is crucially important in demonstrating how blood spatter...

...Human Awareness Essay Should all people convicted of a crime have their DNA fingerprints stored on a database? A DNA fingerprint is the same for every cell, organ and tissue in an organism. DNA fingerprinting has many uses, some of which include providing the evidence needed to solve criminal investigations, determining genetic relationships and solving paternity disputes. DNA fingerprinting has many benefits in the use of criminal investigations as it can provide the evidence to solve crimes and current mysteries, can free innocent suspects and can also cut out a great deal of investigation time. However, there are also many negative issues involved in the matter, such as privacy concerns, which may lead to discrimination and the mishandling or misinterpretation of the DNA evidence. Currently, there is a database where the DNA from samples collected at crime scenes is sored, although many believe that all people convicted of a crime should have their fingerprint stored on there. This raises the question “should all people convicted of a crime have their DNA fingerprints stored on a database?” As everybody’s DNA is unique, DNA fingerprinting is rapidly becoming the main source for identifying and distinguishing amongst individuals. The structure of DNA is a double helix shape made up of a phosphate sugar backbone, which consists of a sequence of complimentary bases held together by weak hydrogen bonds. A DNA fingerprint is manufactured by first extracting the DNA from the...

...(2015) asserts that criminal laws refer to the state laws, which make certain actions illegal and punishable by fines or imprisonment. Accordingly, the case of Casey Anthony falls under the criminal and as such, the forensic evidence gathered from the trunk of her car makes her criminally reliable, as the said evidence is admissible in the court of law. The forensic experts from the Federal Bureau of Investigation (FBI) examined a band of hair recovered from her vehicle, which exposed evidence of apparent decomposition. Forensic analysis of the recovered band of hair showed consistence with the band of hair of the deceased. The FBI experts who conducted forensic analysis on the band of hair told the court that the sample had many consistencies in relation to the post-mortem banding. Moreover, microscopic hair examination specialist told the jurors that the root portion of the air was dark and, therefore, consistent with the evidence presented by the FBI. The analyzed evidence showed that the hair was evicted forcibly from the deceased. Further, an investigator of the crime scene testified that that there was an odor smell emanating from Casey Anthony’s car, which indicted that there was decomposition in the car. All this evidence prompted the court to judge Casey Anthony with first-degree murder when the remains of the deceased were found near the home of the defendant’s parents. However, the defense team for Casey Anthony asserted that the deceased accidentally drowned in the...

...examining all available information of a particular offense (Ainsworth, 2001). The aim is not to identify the offender committing the serious crime; the primary purpose is to establish the type of person likely to have committed the offense. John Douglas argues that you need to “think exactly as the criminal does” in order to understand potentially who could be behind these crimes (Douglas and Olshaker, 1995 p, 151). It can be an effective way in order to capture the perpetrator primarily before they strike again and to gain justice and reassurance for victims. It helps to eliminate a huge swath of the population narrowing down police searches of potential perpetrators. The purpose of this essay is to discuss the strengths and weaknesses in relation to both the UK and US approach to criminal profiling and how effective their methods are in practise. Both approaches are not that different with the techniques used but they differ in terms of the rigorous empirical techniques used by profilers in the UK. I will make reference to infamous case studies to help demonstrate the benefits and drawbacks of using...

...to better improve the criminal justice process? Explain. The three components of the criminal justice system are the police, correctional agencies, and criminal courts. The Police are the first step in the judicial system. They are the first responders to any crime scene which goes into the investigation process. The investigation process will then lead to possible arrests; the criminal is then booked and processed. They are given a court date and from that point the case is in the criminal courts domain. Once a suspect is given a court date the Criminal Courts then conduct a fair and impartial trial. The criminal courts are there to protect the rights of anyone facing processing by the justice system. The suspect is then found guilty or not guilty. If the defendant is found guilty they are then transferred from the county jail, where they were being held, to a state prison or correctional facility. The Correctional Agencies are the final step in the criminal justice system. Sometimes this is the end of the road for some offenders and other times appeals are filed and it will go back to the court system. Correctional facilities have different levels: minimum security and maximum security. The severity of the crime will determine which one of the facilities the criminal will end up in. The changes I would make to the system are the communication between the courts and the correctional facilities. I will give a personal experience; my spouse was a youthful offender. His sentence...

...Choose one global crime as a case study and critically evaluate the effectiveness of the transnational policing of this crime. This essay focuses on money laundering and argues the effectiveness of the transnational policing of this crime; money laundering is one of the world’s most prevailing organised crimes. This essay firstly defines policing from contrasting viewpoints of different philosophers as well as identifying modes of the police. I will explore the modes of policing and various definitions of policing; this essay considers definitions and approaches to policing through a transnational concept with influences from prominent figures within the ideology of transnational policing. The conventional process of money laundering is clarified together with implications of the how this global crime effects other crimes as well as society as a whole. Aided with two case studies I give examples of how money laundering takes place; taking into hindsight the effectiveness of the policing of money laundering. This essay also addresses the connection between money laundering and the risk society theory whilst also taking into consideration the contrasting views of domestic police modes and transnational police modes. Through addressing ways in which money laundering is combated through global organisations such as Interpol, I critically address significant notions of the policing of money laundering. Policing is typically understood as a method of crime control; however the...

...Criminologist and forensic psychologists share many similarities although they have a few differences. This essay will attempt to explain these similarities and differences. Criminology is the scientific study of crime and criminals whereas forensic psychology is the interaction of the study of psychology and the law, it is also a branch of applied psychology which is concerned with the collection, examination and presentation of evidence for judicial purposes (Haward, 1953) furthermore they hold a doctorate degree in a field of psychology. The role of a criminologist is to investigate a variety of reasons to why criminals commit crimes. In order to investigate how these crimes are committed, they must consider psychological and social factors furthermore consider if any biological situations could have led the criminal to commit the crime. The role of a forensic psychologist is to provide the legal system with sound psychological information from a sound research base (Grisso, 1987). A forensic psychologist role is similar to a criminologist role to an extent that they also work with prisoners and offenders moreover they also apply the psychological theory to criminal behaviour to figure out what makes criminals commit these crimes. The premium goal of a forensic psychologist is to The first act of psychologist taking part in the justice court was in 1896 when Albert testified at the trial of Munich man accused of murdering three women. Within the United Kingdom the prison...
