The crime scene technician must interview the first officer at the scene or the victim to ascertain the "theory" of the case. Basically what allegedly happened, what crime took place, and how was the crime committed. This information may not be factual information but it will give the crime scene technician a base from which to start. Examine the crime scene as the second step in the protocol. Examine the scene for what?
When responding to any type of crime scene it is important to remember that anything seen on the way to the known scene as well as on site can possibly be evidence that you will be using later. However when dealing with crimes that are done on computers it takes a certain type of skill to insure that all the possible evidence is gathered correctly so it is acceptable for a court room. In this we will describe the process of computer forensics as it pertains to the collection of computer evidence. Also the type of training required of investigators before they are proficient at the process. There are also specific photographs that need to be taken at the crime scene to ensure a couple different things.
Once the behavioral profile is done, the profiler can then compare this to other criminals or mental patients with the same basic characteristics. It is generally very difficult to get professional hands-on experience on how to be a profiler. Police have been able to catch a wide array of people using profilers, including serial killers. Once criminals have been taken into custody, profilers can learn even more about the criminal mind and can find possible motives, verify motives, and/or assess the defendant's state of mind. The police psychologist does more hands-on work with officers and victims as opposed to criminals.
A insurance company might use an investigator to analyze a car accident to determine whether or not the company will pay for the damages that was done to the car. A law enforcement agency might use an investigator to analyze the crime scene of a homicide or even a robbery to help get evidence to find or prosecute a suspect. A Crime Scene Investigator will have to write reports, take photographs of the crime scene and evidence, sketch of the crime scene, collect evidence, like bullets, weapons, shoe prints, fingerprints, etc. There are several steps you will need to do to become a Crime Scene Investigator. The first thing you need to do is get your high school diploma or G.E.D.
When a performance is rewarded, a subject will produce more of it and naturally when a performance is not rewarded, a subject will produce less of it. It is also known that the government rewards crime labs verifying unknown substances to be illegal narcotics, for finding a driver’s blood alcohol content to be over a certain number and determining a package of drugs is over a certain weight so a heavier charge can be imposed. Police often share their suspicions regarding suspects with lab workers before forensic examinations are performed. This introduces prejudice to lab personnel in areas such as fingerprint examination and chemical testing for accelerants in arson investigations. Some lab examiners feel they are part of the prosecution
The photographs should saw the scene as you found it. 2. Major crime photography a. First discuss the crime scene, evidence and photographs needed with their investigators at the scene. b.
Careful, thorough investigation is key to ensuring+ the potential physical evidence is not tainted or destroyed or potential witnesses overlooked. I am sure many agencies have programs in crime scene processing, the level of training and resources available varies from jurisdiction to jurisdiction.” (Reno, 2000) Assembling a set of guidelines and conducting preliminary investigation for criminal cases are best described by the FBI. The initial responding officer(s) shall promptly, yet cautiously, approach and enter crime scenes, remaining observant of any persons, vehicles, events, potential evidence, and environmental conditions. A FBI report issued in 2005 details that general crimes are outlined into three graduated levels of investigative activity. These activities are the checking of initial leads, preliminary inquiries, and full investigations.
Government agencies use these reports to document crime and do further research on crime in the nation. After a few years of reporting with the first program created, the UCR or Uniform Crime Reporting Program, another program had evolved from that having the FBI designated to coordinate the latest program, NIBRS or the Nation Incident Based Reporting System. With the UCR you could not differentiate between misdemeanor and felony crimes, so the NIBRS was created to gather more in depth and detailed crime data. The NIBRS collects detailed data on every single crime occurrence. Along with those programs came the NCVS or National Crime Victimization Survey, this survey is a self-reporting survey which victims report their own incidents.
One article stated that: Almost every day photography provides new evidence of its value as a powerful weapon in the war against crime. More and more departments are coming to realize that—even in routine incidents—simple pictures taken with simple cameras can make an impressive difference in Court. Furthermore, police departments are continually finding new ways to use photography, both as a tool for investigation and as a means to record data quickly and accurately (RCMP Website, 2002, paragraph 1,2 ). Before a detailed examination of the crime scene is made or before any items are moved or even touched, the crime scene should be photographed. The photographs should be taken to clearly and accurately depict the actual scene, the path taken by the criminal
You cannot out beat the new law enforcement technologies. I watch a lot of criminals show, and I’m always trying to figure out how they are finding out the information. I always thought they were just a group of intelligent individuals, but it’s the technology. If you don’t know about the new technology it will be my pleasure to inform you in the next few paragraphs. The Enclosed Space Protection System and the High Definition Surveying are two new technologies that law enforcement is using.
