When a bullet is retrieved, it is marked with the investigators’ initials at the tip or base. It is very important that the initials do not cover any striations that the bullet may have.…
In light of sniper shootings being on the rise for instance in the Washington area, four states are taking serious consideration in a new technology of creating a ballistic fingerprinting system enabling law enforcement the ability to trace shell casings found at crime scenes back to the maker and or buyer of the fire arm used. As of now Maryland and New York are the sole two states that are using such a database, however only a small amount of fire arms have been recorded so far which is seriously impeding the possibilities and achievements one…
In this case study I will examine the forensic evidence (limited to the main ballistic evidence), that was presented in the criminal trials and the forensic evidence that was introduced by the prosecution.…
The first step I would take in order to transport the weapon to the lab is to make sure the firearm wont discharge accidently on the way to the lab. To do this I need to unload the gun and take all the ammunition out. I would then mark the weapon information about the case number, the firearm's serial number, and the investigator's initials that collected the evidence.…
The last process is to collect and package the evidence in the proper containers. The evidence that is the most important is that evidence that is fragile and can be contaminated easily. This might include fingerprints and blood evidence that could break down quickly. All evidence should be put in separate containers so that the evidence does not get contaminated by another piece of evidence. Firearms should be…
Crime scene investigators oversee a myriad of complex crime scenes such as armed robberies, home invasions, homicides, sexual assaults, and other property crimes. The CSI created a crime scene perimeter before investigating. CSI is responsible for collecting, documenting, securing, and properly storing all of the evidence found at a crime scene. Processing a crime scene can be a tedious process that takes several hours, and CSIs must pay careful attention to every detail to avoid overlooking critical evidence. The entire scene can and will be photographed, either by the CSI, as the evidence is collected. CSIs must follow strict protocols for collecting trace evidence such as hair, fibers, glass, paint, or dirt in order to maintain integrity of the chain of evidence. They record each item that found, including its location and any other pertinent information, and catalog and seal the item for transportation to the lab.…
After the shooting, the rifle purchased by Oswald was found on the sixth floor of the Depository building. (Polidoro 8) Investigators had found the rifle to have hand and palm prints of Oswald on the rifle, as well as fibers from the t-shirt he was wearing that day. (Report of the Presidents Commission..) Do to all the evidence at the location where the rifle was found, other researchers and investigators have done test trials. By doing tests and reenacting the crime scene, they found that the window where the rifle was found in front of on the sixth floor of the Depository Building is a position where Oswald would be able to shoot Kennedy hitting him from behind. (Report of the President Commissions…) Not only are the testing’s accurate but Oswald was also…

In the criminal justice investigation process forensic science and the scientific method are used. The collecting of the evidence is a very important procedure and should be done with…
3. If I were in charge of retrieving bullets at a crime scene, the steps I would take to retrieve the bullet and take it to the crime lab would be marking my initials on the tip or base of the bullet, wrap it in tissue paper and placed in an envelope or pillbox, and be careful to preserve any trace evidence.…
In forensic science ballistics, the study of motion, examines the dynamics, angular movement, and effects of projectile units such as bullets, missiles, and bombs. There are many applications of ballistics within a criminal investigation.…
At the end of the 20th century, gun crime had risen dramatically, this caused problems for forensic scientists as they were an anonymous way to kill someone. One high profile murder case would cause this to change. On the 20th of January 1928, Mr Frederick Browne was arrested on suspicion of robbery. When the police searched his property, they found a type of revolver called a Webley. For several months they had been looking for a Webley revolver that was used to murder a police officer. At the murder scene, which was a car, a gun cartridge from the murder weapon was found. The police sent the cartridge to Robert Churchill, who was an expert in ballistics, he realised that the cartridge belonged to a webley revolver. He put the cartridge under…
Ofc. Peavy advised that the gun has a stovepipe, and he identify the gun as a Smith & Wesson SD 9mm VE, serial number (HFC1500). Ofc. Peavy turned the gun over to Ofc. Skinner until PCSO Forensics arrive on the scene.…
According to Welner (2011) approximately two-thirds of the homicides committed in the United States involve the use of a firearm. Forensic pathologists are able to distinguish the subtle differences between contact gunshot wounds, near contact gunshot wounds, medium range gunshot wounds, and distant gunshot wounds. This process involves both technology and experience to determine various relevant details about the incident such as direction, range, sequence of fire pattern, the path traveled between entry and exit wounds, the likelihood of survival after sustaining a gunshot, the make and model of the gun, and the specific…
Investigation: To first start off the process of criminal justice, a crime is reported and evidence is gathered from the crime scene to help investigators reconstruct and determine what exactly happened. They will also start to establish a list of possible suspects for the crime committed.…
