Crime Scene Investigating and Processing
Throughout the course of this paper I am going to talk about crime scene investigating, as well as, crime scene processing. I will talk about what a crime scene is what makes it a crime scene. That happens at a crime scene, also, what to look for at a crime scene. I will talk about who is involved in processing a crime scene and when or if other jurisdictions need to be brought in.
The first thing that happens when there is a crime being reported is the police are notified by the dispatcher. The police then record the time and the subject of the call. They also need to be sure to record who made the call and what was said during the call. Lastly the police need to be sure to record the dispatchers name and or number. Police going to a call have to be very alert and watch for fleeing suspects, witnesses or victims and the way to the call. They have to record their route to the scene and their time of arrival. Police should always park away from the scene and the evidence. Finally they want to be sure to notify the dispatcher when they arrive at the scene (http://www.rcmp-learning.org/copp/encopp/s_crime/htm).
Once the police have arrived at the scene, they first have to verify the problem. They have to record the time and the situation. They also need to be sure to record how they learned about the crime or who told them. They would also want to record the appearance of suspects. Then they would want to notify the dispatcher of the situation (http://www.rcmp-learning.org/copp/encopp/s_crime.htm).
Another very important priority for the police when they arrive at the crime scene is to give emergency aid if necessary, to all victims, witnesses, or suspects. Officers need to call for medical help immediately but they still need to give the appropriate aid until medics arrive. Sustaining life and minimizing injuries is a top priority of all officers. They are never to assume a person is dead unless the body is already in rigor mortis, or the body is decomposing, or the trunk or head is severed. If there is a death the medial examiner needs to be called immediately (http://www.rcmp-learning.org/copp/encopp/s_crime.htm).
After the situation has been assessed, everything is recorded, and the injured or dead have been cared for the crime scene needs to be protected. This is a major responsibility of the first officers...

... for physical evidence you have to look for items that vary in size. They can range anywhere from large objects to minute substances. It is very important to understand what types of evidence can be found at various types of crime scenes. There will be some things that are not found at the crime scene, however. When investigating a burglary you need to know to look for tool marks on a door or a broken door or window. A forcible rape you want to look at bruises semen stains or witnesses that may have heard screaming. Things like this are very important for an investigator to know to look for (Bennett & Hess, 71).
As you can see there are many different steps in investigating crime scenes. It is very important that an officer follow the proper steps in an investigation. Failure to do this can result in a suspect to go free, possible charges against the department. This is for the protection of the victims, witnesses and the suspects.

In criminal justice, detectives need many skills that help capture the suspect. One of the important skills is finding and presenting evidence. This is significantly important because according to the Criminal Justice
The police are just one agency within the Criminal Justice System All of the agencies within the Criminal Justice System work together. Another agency in the Criminal Justice System is The Ministry of Justice, of whom are responsible for other parts of the justice system such as the courts, prisons and probation services. For example, the police are responsible for keeping the peace and for the investigation of crime, they also collect evidence and arrest suspected offenders. In case of an emergency, the public is able to call ‘999’ and ask for the police to be sent out. Once at the scene the police then makes a decision, if the case is minor, then the police decide whether to caution them, or take no further action. They can also issue a fixed penalty notice, or they can refer to the Crown Prosecution Service for a conditional caution. If it is a more serious case, they send the papers to the Crown Prosecution Service for them to decide on the prosecution. Once sent to the Crown Prosecution Service it is ...
There are many forms of intercommunication that law enforcement officers’ use. One is the radio system that’s placed in their car, the writing on the car is even a type of communication, the dispatcher, and police reports, and these are just a few. Officers used their radio system to connect with each from car to car, so they can call for backup and described the crime scene to each other. The writing on a police car is almost a giant warning or a giant sign that law enforcement is near and ready to protect. The dispatcher as the name already says is the person who tells which officers to go to which citizen distress call or which crime scene. Police reports may be one of the most important though this can make or break a criminal case. They include evidence found, witnesses statements, assumed time of death

Crime scenes are known to have many clues left behind. The obvious would be a the body or bodies, clothing, and sometimes even the murder weapon. While these are great way to solve a case there's another kind of evidence; trace evidence. Trace evidence are small pieces of evidence that are laying around a crime scene. There are many types of trace evidence some of them include metal filings, plastic fragments, gunshot residue, glass fragments, feathers, food stains, building materials, lubricants, fingernail scrapings, pollens and spores, cosmetics, chemicals, paper fibers and sawdust, human and animal hairs, plant and vegetable fibers, blood and other body fluids, asphalt or tar, vegetable fats and oils, dusts and other airborne particles, insulation, textile fibers, soot, soils and mineral grains, and explosive residues. Although these are the most common found elements, they are not the only ones. The Trace Evidence Unit is known to examine the largest variety of evidence types and used the biggest range of analytical methods of any unit. materials are compared with standards or knowns samples to determine whether or not they share any common characteristics. In this paper I will discuss the different kinds of trace evidence and how crime scene investigaros use it to solve cases and convict criminal.
The criminal justice system has changed a lot since the good old days of the Wild West when pretty much anything was legal. Criminals were dealt with in any fashion the law enforcement saw fit. The science of catching criminals has evolved since these days. We are better at catching criminals than ever and we owe this advancement to forensic science. The development of forensic science has given us the important techniques of fingerprinting and DNA analysis. We can use these techniques to catch criminals, prove people's innocence, and keep track of inmates after they have been paroled. There are many different ways of solving crimes using forensic evidence. One of these ways is using blood spatter analysis; this is where the distribution and pattern of bloodstains is studied to find the nature of the event that caused the blood spatter. Many things go into the determination of the cause including: the effects of various types of physical forces on blood, the interaction between blood and the surfaces on which it falls, the location of the person shedding the blood, the location and actions of the assailant, and the movement of them both during the incident. Another common type of forensic evidence is trace evidence. This is commonly recovered from any number of items at a crime scene. These items can include carpet fibers, clothing fibers, or hair found in or around the crime scene. Hairs recovered from crime scenes can be used as an important source of DNA. Examination of material recovered from a victim's or suspect's clothing can allow association to be made between the victim and other people, places, or things involved in the investigation. DNA analysis is the most important part of forensic science. DNA evidence can come in many forms at the crime scene. Some of these forms include hair; bodily fluids recovered at the crime scene or on the victim's body, skin under the victim's fingernails, blood, and many others. This DNA can be the basis of someone's guilt or innocence; it has decided many cases in the twentieth century. As the times continue to change and the criminals get smarter we will always need to find new ways to catch them. Forensic science is the most advanced method yet, but is only the beginning. As the field of science grows so will the abilities of the
Once the officers arrive on scene and talk to the homeowner or business owners they must now for their and the citizens safety get the scene secured in a timely manner. Generally, it is not necessary to go to far lengths to secure a burglary scene because most times the burglar is already gone away from the scene of the crime but they still need to secure the scene just to be safe. They first need to ask the victim to avoid touching anything inside of their home or business, and try to keep them in an undisturbed portion of the scene such as the garage or in the kitchen where its likely the offender did not go through. Traffic through the building should be minimized. This is very important so that when the crime scene team arrives on scene they are able to dust for prints and look for clues that will help them head in the right direction to catch the assailant. In some cases the victims may have already been through their

Crime fighting is incredibly time consuming and can be immensely complicated. As I mentioned before, shows will often lead the viewer on to think that one person does all the work at a crime scene. In reality, the process goes more along these lines: When a call is made that needs assistance, a uniformed officer will be the first one on scene. He will do his job of securing the area and making sure any other threats have been neutralized. If he needs, he will call for detectives to come and investigate as well as interview any witnesses in the area. Shortly thereafter, crime scene units will show up and help in recovering physical evidence such as prints or traces of DNA. Following all of these different units and people arriving, the scene and evidence needs to be photographed, documented, and chronicled. Every single member of the team will record his or her own take on the scene by filling out paperwork (Fact vs. Fiction). The bottom line here is that television is
We have already established that for the police to be involved, the crime has to be committed. Once the crime is committed, someone has to report about the crime being committed and when the report has been made, the police begin its job and starts investigating that report to determine if a crime have been committed. O...
Collecting evidence from a crime scene is a crucial aspect of solving crimes. Before evidence can be seized, there must first be a court order approving the search of the crime scene and the seizure of the evidence found at the scene. Standard protocol for officers is for them to always use latex gloves, avoid plastic bags, double wrap small objects, package each object separately, and to collect as much evidence as possible. It is better to have too much evidence than to not have enough. There are countless amounts of evidence that can be found at a crime scene.
A basic level police officer job is usually driving around on patrol looking for any sort of crime or illegal activity that is going on. A police officer’s day is usually not as dangerous and exciting as shown on tv or movies. Most officers spend their time patrolling neighborhoods or on traffic duty. They are required to patrol areas on foot, motorcycle, bicycle, or in a police car. This helps them complete their tasks for the day. Police officers need to become familiar with the area they are assigned and know any existing conflicts. Officers always need to be prepared to get a call for service at any point in the day. Police officers experience many different types of situations such as injuries, public disturbance, or a serious crime. Basic occurrences they are called to include assaults, domestic disputes, robberies, car accidents, fires, and noisy parties. When arriving at these scenes officers need to take control of the situation properly and immediately. Police officers are not always on the job alone. If there is any situations containing an injury the officers notify first aid to help the inju...

When someone calls the police department after a crime is committed, officers in the area respond to the call. They take statements from parties involved in the incident as well as any witnesses to get additional information and statements. Police officers are also trained in CPR and emergency response systems and show up to aid injured people." (Kokemuller, 2012). Officers must have a short memory while on the job because situations can switch quickly, and they must be able to focus on the current scene.
Reporting a crime could save lives. Every minute that passes, the chance of a crime victim getting help, or the criminal being caught, lessans. In the article, Thirty-Eight Who Saw Murder Didn’t Call the Police”, Martin Gansberg explains, “It was 3:50 by the time the police received their first call, from a man who was a neighbor of Miss Genovese. In two minutes they were on the scene.” In this article it tells a story of a woman who was murdered outside of her home, and how many neighbors heard the altercation but decided not to call the police. If someone who heard her being stabbed the first time would have called the police, there would have been a higher chance of her surviving. Even if the neighbors did not physically see the murder happening, many heard the disturbance. Witnessing or hearing a disturbance calls for you to report it to the authorities. A couple told the police, “We thought it was just a lovers quarrel.” Even if there was uncertainty, calling the police to be safe is crucial in today's age with crime.
