When a bullet is fired from a rifled firearm, the rifling leaves marks on the bullet. Those marks are unique to that gun, and no other gun makes exactly the same marks. If a bullet (or fired cartridge casing) is recovered from a crime scene, and we suspect that YOUR gun was used to commit this crime, then a sample bullet is fired from your gun, and compared to the crime scene bullet. A comparison microscope is used to compare the bullets, or marks made on the fired cartridge case by the extractor and firing pin.
On the sight of the wound, there may be a scar...
YES
If the distance between the person shooting at the criminal and the criminal is large enough, then the criminal can hear the bullet and pull the trigger before the bullet strikes him (depends on his reaction time. If the distance is too small for the criminal to react before the bullet, the chance of his pulling the trigger with a bullet in his head is small.
Trace evidence in criminal investigations was shown by Dr. Edmond Locard in the early 20th Century.
Example sentence - The detective would trace the steps of the criminal activity to help solve the case.
In some criminal circles, placing a bullet in a coffin is a symbolic gesture meant to convey a threat or a warning to others. It signifies that the deceased individual may have been killed as a result of their involvement in criminal activities or as a consequence of crossing certain individuals within the criminal underworld. The bullet serves as a reminder of the potential consequences of betraying or opposing the gangster's code of conduct.
Tracer ammunition contains pyrotechnic composition at the base of the bullet, which ignites upon firing to create a visible trace of the bullet's trajectory in flight. This allows shooters to track the path of the bullet and make adjustments if needed. Tracer rounds are primarily used for training purposes or in military applications.
you cant trace the address of any mobile no. directly... if someone is giving it then that will be the criminal offence according to Indian government...
It means you better watch out because they're coming for you. And chances are, if you are the criminal, by having posted this question on the internet, they can trace exactly where you are and can easily arrest you.
Yes, forensics experts can use a process called ballistics analysis to match a fired bullet to the gun that fired it. This involves examining unique markings left on the bullet by the barrel of the gun, such as striations or rifling marks. By comparing these markings with test-fired bullets from a suspected gun, investigators can determine if there is a match.
If the glass fracture resulted from when a bullet hit the car windshield, police can predict the bullet type and therefore the kind of gun used. If they trace the purchase of that type of gun, this narrows their suspects. they may also be able to say something about a bullet's trajectory, or they may be able to determine from which side the glass was impacted.
Locard's principle of exchange is important in criminal investigation because it states that every contact leaves a trace, allowing investigators to link suspects, victims, and crime scenes through the transfer of evidence. By identifying and analyzing these trace materials, investigators can reconstruct events, establish connections, and ultimately solve crimes. This principle emphasizes the significance of collecting, preserving, and analyzing physical evidence in criminal investigations.
