Description And Explanation Of Retrieval Or Group Methods Used

Forensic ballistics and firearm investigation begin when the bullets, cartridges, a weapon, or any combination of the above found at a crime scene. With the evidence, a crime laboratory will explore for clues on some things that might cause a suspect or possible to prove that the things were used in the crime. By contrast, the markings on the bullets or cartridges found at the scene with those discharged from the suspect’s weapon, a ballistics expert will typically confirm if the rounds came from a similar weapon. Just the act of cycling a cartridge through the weapon without firing it will leave permanent scratches on the case that is distinctive to the weapon.

If I were in charge of retrieving bullets at a crime scene I’d first I would have to find a way to remove the bullet out while preserving any possible markings on the bullet. Then the bullets can be placed into a marked container for identification purposes. Then to transport the bullet to the crime laboratory, I’d wrap the bullet in tissue paper and placed in an envelope or pillbox. I would have to be careful with the handling and packaging of the bullet, because I would have to be careful to preserve any trace evidence that might be present on the bullet.

Thoroughly document scenes and gather potential evidences (physical, specimens, documents, photographs, statements etc) to send to crime lab

Do you know what the steps are when it comes to processing firearms evidence? The first step to processing a firearm as evidence is to put gloves on your hands. Then you should take pictures of the gun when you find it at the crime scene. Make sure the picture is as clear as possible because it will be used in the court room. Make sure you included some form of measuring the gun that is in the picture. Next, take the bullets out of the gun and put the bullets in a line. Take a picture of it so the court can see the amount of bullets that was found at the crime scene in each gun. You also need to take pictures of all of the empty bullet shells that you may

Firearms that are left behind at a crime scene can be extremely helpful. This evidence includes not only the firearm itself but also the ammunition used in the firearm, componets that make up the firearms, and the residue that comes out when the

In the event that any firearm is discovered at a crime scene there are certain steps that need to be done in order to properly collect any type of firearm evidence. If there is any kind of firearm found at the scene it should be rendered safe immediately. For safety is the first priority at any crime scene. Forensic technicians should assign an evidence number to the firearm, photograph orientation and close-up view’s, and take measurements of the firearm’s location prior to collecting it. In order to deem a semiautomatic pistol safe, the forensic technician should be wearing latex gloves an unload the weapon as follows; (Tina Young, 2011)

Along with everything else in Forensics, you want to make sure you wear the proper gloves and facemask to avoid contamination of evidence. Make sure the weapon is unloaded before you submit into the lab. In the case of a revolver you want to make sure to note stating which chamber was in the firing position.

This paper will tell some basic ways of collecting the evidence and how to preserve the evidence without contamination. It also tells how to remove a bullet from surroundings as well as a deceased body.

Other important procedures of handling firearm evidence include recording the serial number of the firearm and it matches the number on the photo, the make, the model, and caliber of the weapon. The bore of the gun should never be cleaned as well as the chamber and the cylinder before a firearm is submitted. Guns must be placed in strong cardboard or wooden boxes to avoid shifting in transit. A weapon should never be picked up by placing a pencil or other object at the end of the barrel. The best way to avoid contamination of evidence is by wearing gloves and a face

Firearms in the United States have always been very controversial, no matter what regulations we have put in the past, there is always something new. When a firearm is found at a crime scene, it is most likely the weapon or one of the weapons used to commit the crime or a killing. Firearms evidence is usually encountered in crimes against persons such as homicide, assault and robbery; but may also be found in other crimes such as burglary, rape, and narcotics violations. The first step into processing the firearm would be taking pictures and videos of the area and position the firearm was found at. The firearm is not to be touched with any bare hands or moved before pictures are taken. Safety is always the first concern if a gun or firearm goes off on anyone if the safety isn’t on. If the firearm is considered or known to be unloaded, it may be picked up with gloves on, and transported safely where it needs to go. If it is loaded, it should then be unloaded, with care taken to preserve all types of possible evidence.

Integrity of Evidence The FBI Crime Lab has come a long way since it opened. All began in the 1920’s, when a person named J. Edgar Hoover recognized the importance of scientific analysis in criminal matters (Forensic Science Communications, 2007, para. 1). Ever since that moment the crime grew a lot. The use of technology to solve crimes increased tremendously overtime.

The book gives a general overview of the field of forensic science. The sections of the book include “The Scene of the Crime; Working the Scene--The Evidence; Working the Scene of the Body Human;

The main provision in all cases is the avoidance of including fingerprints to evidence, or of ruining the ones already existing at the time. Once the crime scene has been carefully recorded and each of the evidence located have been annotated, then the process of gathering and analyzing can commence. The crime scene investigator will start by collecting the most delicate and easily prone to be lost evidence. Locating latent fingerprints at the crime scene requires use of techniques that makes it ideal for visibility. Investigators will use a several of methods to visualize the print, however it will depend on the surface that print is being lifted from. All non-movable and fixed items at a crime scene sustained to be handled on the scene using one of

In any case, during the initial canvass of the crime scene, documentation is made to identify where evidence is and the type of evidence found. After it is recorded in an evidence log the collection of evidence can begin. You will want to start with collecting “the most fragile or most easily lost evidence” (Shiro, n.d.). Throughout the collection process you will want to keep evidence in order by documenting in the log where it is and taking photographs of each item. If additional items are found underneath the other evidence, this should be documented in the log and “photographs should also continue to be taken if the investigator is revealing layers of evidence which were not previously documented because they were hidden from sight” (Shiro,
