From this type of profiling an offender can be categorized as organized nonsocial offenders and disorganized asocial offenders. The killing from theses two types of offenders would produce two different crime scenes, one of complete chaos and plenty of evidence all over and another with little evidence and more controlled. A major benefit from using this type of profiling is that it let investigators know what kind of offender they will be dealing with so they know how to proceed with the case and interrogate them. A limitation from this type of profiling can be that too much attention is paid to the physical evidence and not on the nonphysical (Holmes & Holmes,
A victim survey is where people get asked what crimes have happened to them over a particular period of time. This is different from the British Crime Survey (BCS) or the Crime survey for England and Wales (CSEW) -which is an annual victimisation survey that is carried out by the Home Office; it tries to find out about crime that has not been recorded by the police. Both of these types of survey and therefore types of statistics that you can collect, these differ to the statistics produced from the police because of many ways. One example is that the statistics that come from the police just come from reported crime whereas victim surveys come from people’s experience of crime. Another example of how statistics from the police and statistics from victim surveys are different is because not all victims report crime to the police for many reasons and therefore create what’s called “the dark figure” (The number of crimes that go un-reported, we have no idea how big or small this number is).
Crime Reporting and Reporting Crime: Uniform Crime Reports vs. National Crime Victimization Survey Vanicia Carr Roosevelt University Abstract The Uniform Crime Reports (UCR) and the National Incident-Based Reporting System (NIBRS) are two reports in which the Federal Bureau of Investigation uses to measure crime across the United States. Through traditional methods of collecting crime data to new and improve ways of collecting data the UCR/NIBRS program has been an important part of the FBI crime reporting, however, the program falls short on crimes not reported. With the development of the National Crime Victimization Survey data is collected on unreported crime. Weakness and strengths are presented on each program, with particular emphasis on domestic violence. The strengths of the NCVS outweighed the UCR/NIBRS program in measuring domestic violence.
Through the four steps of the scientific method an investigator can put the pieces together and solve the investigation in a thorough and complete fashion. A criminal investigation refers to the process of collecting information (or evidence) about a crime: (1) determine if a crime has been committed; (2) identify the perpetrator; (3) apprehend the perpetrator; and (4) provide evidence to support a conviction in court (JRank, 2010). These four steps would be how the scientific method would fall into criminal investigations. This can be taken into consideration as to what investigators used when trying to identify and solve the Green River Killings in the Seattle and Tacoma, Washington area between
* Elevation sketch – portrays a vertical plane rather than horizontal for things such as bloodstain patterns. * Exploded view – consists of a combination of the first two sketches. * Perspective sketch – depicts the scene or item of interest in a 3-dimensional sketch. Writing a crime scene report: Identify the crime, included the time and place of the crime (provide the address), include the names and contact information of everyone involved, describe the scene (as above), describe injuries that were sustained and organize the report in an appropriate manner.
The lead profiler on any case can be someone from within or outside the department depending on the skill levels available internally and preferably, a teamwork approach to case analysis would create a continuing dialogue that would not entirely hinge on the opinion of one investigator or profiler. While it is desirable to narrow the suspect list down to a workable size for the investigators, it is also necessary to prevent personal whims from causing tunnel vision and causing the exclusion of viable suspects. The four basic skills necessary for good Investigative Criminal Profiling - investigations, forensics, psychological assessment and the application of cultural anthropology - are necessary to a complete an accurate profile. It should be recognized that experts should be consulted to fill in the gaps. A homicide investigator with limited skills in profiling might combine his skills with that of a professional profiler and as a team, increase the success of the
The criminal justice funnel refers to the process through which the number of criminal matters pending is decrease until only a small percentage of cases need to be resolve by trial advocacy and incarceration.

The management of the courts must be efficient and up to date so that the criminal caseload can be adjudicated fairly, appropriately, and promptly. In many systems, judicial officers are involve in the day-to-day administration of courts, yet it is recognize that too heavy an administrative burden on judicial officers may result in a loss of efficiency. the manner in which the court system is structure and run affects the extent to which members of the public obtain access to the justice system.
This first step requires complete background information on the victim, all available forensic information, and any and all crime scene and case information gathered thus far by the police. However, it is vital that none of the case information pertaining to possible suspects is included, this information could subconsciously bias the profiler, and cause the profile generated to directly point to one of the selected suspects. For the background information, the report should cover domestic setting, employment, reputation, habits, fears, physical condition, personality, criminal history, family relationships, hobbies, and social conduct. The forensic data should also be very in depth including autopsy reports, toxicology reports, autopsy photographs, photos of wounds, the ME's findings, estimated time of death, cause of death, type of weapon, and suspected sequence of delivery of wounds (dragonnet 6). All of this information can allow the investigator to determine factors such as, the degree of control by the offender, how risky it was for the offender to hit his target, his emotional state, and the offender's experience and sophistication as a
Senior Capstone in Criminal Justice: CRJS400-1303B-02 Unit 2 Group Project Individual Portion Margaret Burnett Pro. Ferguson Tire Tread Analysis Unknown tire tracks are pretty much treated the same way as footwear impressions when found at a crime scene. But, the focal point is to preserve any impressions to be later examined by forensic experts. Before they are moved or handled at a crime scene, they have to be photographed, and taken from various angles showing the visible details of the impression and its position in relation to the remainder of the crime scene. These photographs are a backup procedure because they provide a point of comparison only when analyzing the actual preserved impression.
Each and every firearm is created differently thus creating its own identity making it rather easy to link a bullet to a firearm. From the creation of the firearm to the identification of the bullet all aspects are looked at by forensic scientists to determine the sequence of events that occurred leading up to the crime. Throughout history the nature of forensic ballistics has grown from comparing the nature of the bullet while in motion to the science it is today that includes all identifications processes. In the world of forensic ballistics or firearms identification there are many important factors that need to be looked at when attempting to fit
