The Death Of The Sheriff Department Created A Cold Case Squad

“The examination process typically begins when an examiner receives a suspect firearm, along with bullets (the projectiles) and spent cartridge cases recovered from a crime scene.”

An investigator can learn and benefit from findings of a cartridge or casing by the stringent marks on a bullet that was fired from a firearm. Also, examiners have the power to expound on the purpose and capabilities of a firearm.

Firearms evidence is a key to capturing a shooter. Firearms evidence can be found at different types of crime scenes; from homicide to rape. Forensic technicians can determine the distance of a shot based on power residue, they can compare cartridge cases and bullets to particular guns possibly used at the crime scene and link them to owners, forensic technicians can also determine the sequence of shots fired and trajectories. Gunshot residue found at a crime scene can be matched with that found on suspect’s hands. When a firearm is located at a crime scene, a forensic technician must first of all diagram and photograph it before collecting it. It is important to treat every firearm found as if it were loaded. Every situation must be carefully

Goddard composed an article in 1925 titled “Forensic Ballistics”. This article explained the analysis of firearm evidence by using a comparison microscope. The comparison microscope

One way that this is done is to study the makeup of a firearm which has different elements and markings that are left behind when the firearm is used. The gun barrel itself are different from gun to gun. The barrel is produced from a solid bar of steel that has a hollowed out. The inner surface of the gun barrel are randomly irregular which sets one gun

Evidence of the bullet embedded into the wall behind the counter is actually a fixed or non-moveable item. The investigator will not dig the bullet out at any time. We will cut a portion of the wall around the bullet and send to the lab for further ballistic, touch DNA and possible fingerprinting. Touch DNA would be collected with a buccal swab as previously stated and the superglue fuming method for a possible fingerprint when all other evidence is collected. The piece of wall will securely place into a box, to ensure no movement, sealed and sent to

A case that lasted 4 decades was solved using ballistic forensic science! Ballistic science is all over the world to solve numerous crimes in numerous ways. It is a major part in forensics because in our time now, people are using guns to commit crimes more than ever.

Indescribably, technology has entered every aspect of our life and to no surprise has become almost futuristic as it helps define our crime solving abilities. Forensics actually is the fastest growing criminal justice field in America. Seemingly always in the background, forensics is a major part of our criminal justice systems as a whole. Forensic Science has contributed to our world a great deal in multiple ways, and very significant ways. By the close of the 20th century, forensic scientists had a wealth of high-tech tools at their disposal for analyzing evidence from polymerase chain reaction (PCR) for DNA analysis, to digital fingerprinting techniques with computer search capabilities (Stephanie). To start off, Criminal Investigation is the largest and most known form of Forensic Science. Some of the more known areas include Fingerprinting, Ballistics, DNA Identification, Fiber Samples, Computer Animation, and Documentation analysis.

If there’s dried up blood on some furnishings at the crime scene, the Crime Scene Investigators will attempt to direct the whole section of furnishings to the laboratory. A sofa is not an infrequent piece of substantiation to assemble. A Crime Scene Investigators might uses combs, tweezers, containers as well as a filtered vacuum apparatus to assemble any hair or else fibers at the crime scene. The Crime Scene Investigators hallmarks any hair or else fiber proof in distinct ampules for conveyance to the laboratory. If a Crime Scene Investigators discoveries any guns, ammunitions or casings at the crime scene, she or he should put gloves on, pick up the firearm by the barrel then bags everything unconnectedly for the laboratory. Forensic technologists can recuperate serial figures and

According to five metal residues found from the inner wall of the truck cabin, all five metal residues can be classified into three groups: a deformed full-copper-jacketed bullet, .38 (9 mm); two residues of copper-jacketed bullets, size and class unidentified; two lead residues of the bullet, size and class unidentified. All these evidences are ammunition in accordance with the Firearms Act Ammunition, explosives, fireworks and imitation firearms (No. 3), B.E. 2501 (1958): Section 3

While analyzing this evidence, several units in the crime laboratory will be used like: the document unit, firearms unit, latent fingerprint unit, and biology unit. The document unit will be used for the note found on the crime scene that the victim wrote, it could be analyzed to see if it was legitimately the victims writing or if someone else wrote the note to cover up the murder and make it look like a suicide. The firearms unit will help figure out if that was the murder/suicide weapon. The latent fingerprint unit will try to find a match on the faint fingerprints found on the revolver, whether they belong to the victim, the owner of the gun, or someone else who shot the gun itself. If they cannot find a match they will try to reconstruct the fingerprints to possibly find a close match.

In the last part of the 20th century (1970-1999) saw the greatest and most significant advances in the science of ballistics, due to the ability to fully utilize the vast potential of computers, this has also allowed science and specifically forensic science to develop several useful “tools” for use within firearms laboratories including the current Integrated Ballistics Identification System (IBIS) , which allows for the capturing of digital images of fired bullets which are analyzed to provide possible ‘hits” from the National Integrated Ballistics Identification System (NIBIS) for examination using a comparison microscope, this technology was unheard of just a few years ago. (Hamby, 1999)

One method to determine the marks on a cartridge case is using a comparison microscope. Using the scope you can compare the cartridge cases against fire standards. Scientists first examine the standards in order to determine what firearm is constantly reproducing certain marks. The experts would then compare their findings to the evidence on the cartridge cases to see if they have any matches.

The researcher is confident that these police investigators had experienced to investigate criminal cases which involve the use of firearms and can asses the effectiveness of the application of firearms identification in resolving firearms-related crimes.

What are the different types of ballistics that we study in the field of criminal justice? We study three main types they are: internal, external, and terminal ballistics. Internal ballistics is the interior workings of a weapon and the functioning of its ammunition. External ballistics is the study of the flight of the bullet from the mussel of the gun to the target. Terminal ballistics is what happens to the bullet once it hits the target. We will take a closer look at each one of these throughout this paper.
