INTRODUCTION
This project deals with the procedure followed in ballistics section of forensic science lab where cases duly reported in which firearms are involved. Some of these cases will be studied in detail also their lab examination. Before entering into the topic it is important to picture a brief idea about what is ballistics and what is a firearm. Ballistics is a science specifically mechanics that deals with the launching, motion and behavior of a projectile both in air and on the target as well as effect due to the launched projectile on the target. On this basis ballistics is divided into three major parts
1. External ballistics
2. Internal ballistics
3. Terminal ballistics, respectively.
This projectile includes especially bullets, missiles, drop down rockets, etc. The device that is used to fire or launch these projectiles, it is a firearm. A firearm is a device to hurl a projectile or projectiles. The force is supplied by the creation and expansion of gases usually from the burning of powder charge. In air rifles and pistols the projectiles are hurled by the expansion of compressed air.

The frequent and reckless use of firearms by extremists’ elements in some areas of the world has assumed an almost new dimension. A firearm expert has, therefore, to play an increasingly important role in criminal investigation. To meet the challenge posed by trigger happy anti-social elements, the science of “FORENSIC BALLISTICS” covers the science of identification of firearms and ammunition – application of this science to solve problems connected with incidents in criminal investigation. Whereas ‘BALLISTICS’, a branch of ‘Applied physics’, means the science of motion of projectiles, the word ‘FORENSIC’ is synonyms to legal and is, therefore, more appropriate in this context. The phrase ‘Forensic Ballistics’ was first coined by Colonel Goddard of the United States Of
In the forensic investigation, there were 6 pieces of forensic finding used in Timothy McVeigh trial. The first set of the finding was the earplugs that he wore to silent the noise of the explosive. Meanwhile, there was a trace of residue found in his jean pockets along with two t-shirts and a knife with the sheath. Therefore, due to the positive mixture founded on McVeigh, the prosecutor believe that McVeigh was involved in making a bomb from a mixture of ammonium nitrate and fuel oil. It was believed after, Timothy McVeigh also participated in placing the barrel of bomb ingredients in the back of the rental Ryder truck.
This first analysis paper will be based on the case of The Murder of Stanley Van Wagner. This case involves a husband, Stanley Van Wagner, who was found dead on May 15, 2015, with bullet shot wounds. The perpetrator involves Stanley’s wife, Amy, who was charged with the murder of her husband. All of the inculpatory evidence found at the scene where Wagner was found, points to Amy as the murderer, that is from the gun that was used, a .380 caliber handgun. After some investigating, it was found that Amy had a registration for the exact same type of handgun.
With ballistics, they observed the ammunition and could project where the victims where, when they were shot and where the criminal was placed. They can also check the ammunition and weapons and trace them to their exact location of the sale and who sold it. Well the only testimonial evidence was all the interviews that happened after the crime, which helped the sheriff’s office put together what had happened. They could not be used to convict the criminals because they committed suicide before they were arrested. The only evidence that was used to convict someone was the ballistics report which helped the police see who sold the guns to Dylan and
When Roger’s was initially arrested for the murder of Joshua Tucker on the night of June 5th, 2014 they needed to test for gunshot residue (GSR) on his hands and clothing. It is unclear as to whether or not they did but for the case of this paper we shall say they did. While collecting evidence of GSR you need to make sure the suspect does not have a chance to wash his or her hands. Doing so can and will hinder the investigation because they would have the chance to remove evidence.
Gun control has been a controversial issue for many years. Many citizens believe that if gun control is strictly enforced it would reduce the threat of crime. People have the right to bear arms for protection, or even just the pleasure of hunting and recreational activity. With the recent events involving firearms and mass shootings, people are skeptical whether to increase or decrease gun laws. Americans have a constitutional right to own handguns and stricter laws and licensing will not effectively save lives.
“A monday shooting at a Los Angeles police station was stopped in seconds by an officer carrying a weapon.” (stockman 6). Rifles have been a key tool in law enforcement for years upon years. “The spree ended when the killer was confronted by a military police officer with a weapon.” (stockman 3).
Weapons are deemed as a significant element for military strategies all over the world. Overtime, these illicit weapons distributed to police forces have caused injuries some at minor at levels and whilst some are deemed at extreme levels. Electronic stun devices and other less-lethal weapons are marketed as offering unmitigated benefits to both police and public safety, with this statement there are various problems also associated with these devices such as unnecessary injury and deaths. There are various intentional injuries that police officers are affected by whilst working, the prevalence of injury in the force is rather high. By the 1800s, after departments and police departments distributed weapons and demanded the use of force that
In modern society, guns are seen as a form of control. Those who have guns are able to overpower those who do not. This trend was set when guns were first invented and has stayed the same throughout history. The one place where guns are not a symbol of power and control is in literature, specifically “The Old Gun” and Hamilton. In Mo Yan’s short story “The Old Gun”, the protagonist is a hungry boy who does not even know how to use the titular firearm.
“Moore later showed law officers where to find the gun. Grooves in the gun were similar to markings found on the fatal bullets, though an expert testified that the particular grooves were fairly common and could be found in other weapons” (Wuornos v. State, 1994). The gun evidence alone would not be sufficient enough to
The murder case of Leanne Holland exposed the ways in which forensic science were both a help and a hindrance to the conviction and subsequent overturning of the verdict, against Graham Stafford. The body of 12-year-old Leanne Holland was found battered and partially naked in scrub 30m off Redbank Plains Rd on September 26, 1991. She went missing on Monday morning on September 23, 1991. According to descriptions, she was last seen wearing a long-sleeved purple jumper, black skirt and no shoes as she headed towards shops just 500m from her Alice St home in Goodna.
At a news conference, Michael Bouchard of the U.S. Bureau of Alcohol, Tobacco and Firearms told reports the rifle “has been forensically determined to be the murder weapon”. Investigators were able to match Muhammad’s rifles to 11 of the 14 shootings by a series of ballistic tests. First the bullets were recovered from the victims. When the rifle was found they were able to match them up by the markings or rifling impressions pattern on the fired ammunition by the barrel of the rifle. The rifling pattern in the barrel that fired a particular bullet can be determined by counting the number of groove or land impressions around the circumference of the bullet.
A weapon in the wrongs hands is the maximum danger humanity can face. Nowadays, violence and delinquency in society are viewed as the maximum problem solver. Humanity is full of chaos; hate and envy seize our souls. Guns are the ultimate security for some citizens but for others, these add to a feeling of defenselessness. Throughout history, any topic related to guns means a plethora of problems.
Thus, I recognized that gun ownership is a serious social problem. This problem surely threatens ordinary people’s lives in the United States. To handle this problem, I did some research about the
Title: Gun Safety Rules and Tips Guns are inherently dangers and should be handled with care. Improper use, storage and care of firearms leads to unintentional deaths, injury or damage. If you are a firearm owner, a potential gun owner or a curious about the use and effects of guns, then learning about gun safety is essential. Gun safety rules are the recommendations given to minimize or eliminate accidental or negligent discharge and the consequences of malfunctioning firearms. They also impart knowledge on properly storing firearms.
2. Disassemble the gun – You have to dismantle your firearm in order to clean it thoroughly. However, you should always follow the instructions provided by the gun manufacturer. This is important since taking a gun apart carelessly may result to problems in assembling it later. Rifles and semi-automatic handguns often need to be stripped into their main parts (slide, barrel, magazine, frame, etc.).
