...Topics Crime Scene Investigator In: Other Topics Crime Scene Investigator 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. Before the job of CSI can begin, there has to be a crime committed. 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 of evidence play an important part in finding out valuable information towards solving a case. The most important aspect of evidence collection and preservation is protecting the crime scene...

...On occasion crime scene investigators or lab personnel may have to testify in an array of courtroom proceedings, these range from preliminary hearings, pretrial motions, and the trial itself (Buckles, 2007.) It is important for the investigators to be well prepared and follow a methodical plan of investigating and evidence gathering before the process of going to trial even begins (Buckles, 2007.) Initial court appearance does not require the presence of investigators or lab personnel; however, when the time comes to present the evidence to the judge to establish probable cause that a crime was indeed committed and the defendant was the perpetrator of the crime the presence of the personnel and investigators are then required (Buckles, 2007.)...

...* Dayani Herrera * Week 2 Assignment The Chain of Custody Process Limiting Access to the Evidence * When a piece of evidence is collected, there are numerous individuals who will have access to it before the case goes to trial. The investigator, evidence technician, property officer, laboratory technician, prosecutor and defense attorney all may have custody. Each individual in this chain has a responsibility for the safe-keeping and preservation of the evidence while it is in their possession. Initial Collection * Before any evidence is removed from the crime scene, there should be an evidence custodian designated as the person in charge of initiating and maintaining all evidence. This person needs to document the crime scene location, as well as his time of arrival. There should also be a crime scene log established, witness list and documentation of identification, arrival and departure times of all law enforcement crime scene personnel. Record Keeping * The investigator who handles the evidence initially should affix her name, badge number and assignment to the package containing the evidence. When the evidence leaves the officer's possession, a record should be made in her case notes identifying to whom the evidence was given, the date and time, and the reason it was turned over. A signed receipt should be obtained from the person accepting the evidence and another signed receipt should be obtained when the item is returned. When the item...

...Crime Scene Reconstruction Devry University Kemisha Askew October 20, 2012 The topic I am writing about is Crime Scene Reconstruction. Crime Scene Reconstruction is the use of scientific methods, physical evidence, deductive reasoning and their interrelationships to gain explicit knowledge of the series of events that surround the commission of a crime. Crime Scene Reconstruction looks at the physical evidence and attempts to determine “What Happened? And how did it happen?” The reason why I have selected this topic is because I find it intriguing how physical evidence is broken down, evaluated, and reconstructed to actual tell how a crime occurred and what happened in the process. There are many television shows I watch daily that portray the crime scene investigation process in a certain light this is another reason why I chose this topic. I’d like to find out firsthand what actually goes on in the reconstruction process versus fictional exploitations of it on television. Crime Scene Reconstruction looks at the physical evidence and attempts to determine “What Happened? And how did it happen?” A similar method that is used is Criminal Profiling. Criminal Profiling is the application of psychological theory to the analysis and reconstruction of the forensic evidence that relates to an offender’s crime scenes, victims and behaviours. Crime Scene Reconstruction is the use of scientific methods, physical evidence, deductive reasoning and their interrelationships to...

...A Forensic Nightmare Shepherd Leach CRJ311 Dawn George March 25, 2013 The Enrique Camarena case was one of many mistakes on the part of the corrupt Mexican government. Evidence was improperly collected, scenes were contaminated and much evidence was lost or destroyed. The United States did what they could do and collected what they were able to collect to try and solve his murder and the murder of another agent. This paper will discuss the evidence that was collected, the steps that the investigators followed the many mistakes that were made and what was done well and what could have been done better. In the end the case was tried and the right people were convicted and the mystery solved. The case begins in February of 1985 with a man being shoved into the backseat of a small car from in front of a restaurant where Mr. Camarena was to meet his wife for lunch. This is also when the first of the mistakes in this case were made. A couple of well known drug traffickers were detained as suspects and then allowed to go, only to have it come out later that the Primer Comandante of the Mexican Federal Judicial Police was paid a six figure bribe for allowing the drug traffickers to go. The forensic evidence found in the case of Enrique Camarena was that of a small piece of burial sheet, a piece of rope, a portion of a pillowcase, lab reports, hair, fingerprint and soil samples and some fibers from a nylon rug or carpet. Most if not all the evidence was...

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...

...Search Patterns When a crime has been committed and investigators need to search for evidence, there are different search patterns that investigators can choose from. These search patterns include spiral, line, zone, and grid (Siegel & Mirakovits, 2013). Depending on the crime scene, the investigator will choose from one of these search patterns that will best utilize the search for evidence. When an investigating team needs to search for evidence in a field where the field is overgrown, a grid search is a good search to utilize. When a field is overgrown, the searches may have to crawl on their hands and knees to locate any evidence and perform a thorough search. A grid line search consists of searchers following a line pattern and then following another line pattern that is perpendicular to the first line pattern (Lee, Palmbach, & Miller, 2001). The grid search pattern is a good search to utilize because it allows two different searchers, or the same searcher, to search the same area twice. Therefore, the searchers a more likely not to miss any evidence that needs to be collected. A con to the grid line search is that it is very time consuming and if the boundaries to be searched are not well established, than the search will not be very thorough (Lee, Palmbach, & Miller, 2001). The grid line search was chosen for this scenario because a thorough search can be accomplished by having two different searchers look over the same area. If one searcher...

...procedures are utilized today to help investigators solve our everyday mysteries when it comes to crimes? In addition, what forensic aspects in the video “Welcome to Homicide” were used to finally get a confession of murder? This paper will discuss these topics and elaborate on some of the key evidence that was used to close this particular case. First, let’s begin with where and when forensics is aid to have gotten its start. The basic sciences began to develop in the late 18th century, and many of the early developments in forensic sciences took place during the 19th century (Gaensslen & Larsen, 2013). People long ago did not have technological and scientific advancements that we take for granted in the forensic sciences today. Instead, they mostly relied on forced confessions and testimonies of witnesses. This, naturally, allowed for many criminals to walk free while a lot of innocents were wrongfully convicted. The first known instance of forensics being used was in the year 1248. A Chinese man, called a death investigator, used experimentation to determine that a victim's fatal blow had resulted from the strike of a sickle (Dirkmaat, 2012). What we think of today as forensic science may have been born in China, but truly developed in Europe during the 1700's. German medical experts, Swedish chemists, and Italian surgeons wrote books, developed theorems, and practiced routines that would eventually mature and grow into the crime scene investigation techniques that...

...physical crime scene procedures. In this model, each digital device is considered a digital crime scene, which is included in the physical crime scene where it is located. The investigation includes the preservation of the system, the search for digital evidence, and the reconstruction of digital events. The focus of the investigation is on the reconstruction of events using evidence so that hypotheses can be developed and tested. This paper also includes definitions and descriptions of the basic and core concepts that the framework uses. 1 Introduction Since the first Digital Forensic Research Workshop (DFRWS) in 2001 [Pal01], the need for a standard framework has been understood, yet there has been little progress on one that is generally accepted. A framework for digital forensics needs to be flexible enough so that it can support future technologies and different types of incidents. Therefore, it needs to be simple and abstract. On the other hand, if it is too simple and abstract then it is difficult to create tool requirements and test procedures for each phase. For this paper, we have examined the concept of an investigation to determine what is required. The result is an event-based framework that can be used to develop hypotheses and answer questions about an incident or crime. Hypotheses are developed by collecting objects that may have played a role in an event that was related to the incident. Once the objects are collected as evidence, the investigator can...
