What are the principles in forensic ballistics?
Principles in forensic ballistics include examining firearms, bullets, and cartridge cases to determine their source or connection to a crime. This involves analyzing the characteristics of these items, such as rifling marks, to match them to a specific weapon. Forensic ballistics also encompasses reconstructing shooting incidents to determine trajectories and angles of bullets.
How do you collect bullets in a crime scene?
Bullets are typically collected at a crime scene using evidence collection protocols such as wearing gloves, using proper tools like forceps or tweezers, and placing each bullet in a separate container to prevent cross-contamination. It is important to document and label each bullet with relevant information like location found and any identifying marks. Law enforcement should follow proper chain of custody procedures to ensure the integrity of the evidence.
How fibers help solve a crime?
Fibers found at a crime scene can provide valuable information such as the type of material, color, and potentially where it came from. By analyzing fibers, investigators can connect suspects to crime scenes or link different crime scenes together. This evidence can help establish a timeline of events and create a stronger case in court.
What is the scope of forensic ballistics?
Forensic ballistics involves the examination of firearms, ammunition, and bullet trajectories to link evidence to a specific firearm. It is used to determine the type of firearm used in a crime, the distance from which a shot was fired, and to match bullets or cartridge cases to a specific gun. This field is essential in investigating shootings and linking firearms to criminal activities.
Why is it important that a crime tech know about wavelengTHS and light energy?
Understanding wavelengths and light energy is important for a crime technician because it allows them to properly analyze and interpret evidence such as fingerprints, bloodstains, and fibers. Different materials react differently to various wavelengths of light, which can reveal hidden or obscured details that are crucial for solving crimes. By knowing how to use different light sources effectively, crime technicians can enhance the quality of their forensic analysis and improve the accuracy of their findings.
How ballistic evidence can help investigate?
Ballistic evidence, such as bullets and cartridge casings, can provide crucial information in a criminal investigation by linking a firearm to a specific crime scene or victim. By analyzing the unique markings left on bullets and casings during the firing process, forensic experts can match them to a specific weapon, helping to identify suspects or corroborate eyewitness accounts. Additionally, ballistic evidence can indicate the type of firearm used, the trajectory of the shots, and can even help reconstruct the events of the crime, enhancing the overall understanding of the incident.
Why does a firearms examiner test fire bullets from a suspects barrel?
because when you buy a firearm it comes with two spend casings to show the fireing pin strike on the primer and if the pin strike is the same as the one on the casing that was used in a crime then they know it was your gun. the only way you can avoid this is to change the fireing pin with a different one.
What might it mean if a crime scene investigation finds five bullet holes uses the trajectory rods and finds two different sets of intersections?
Finding five bullet holes with two different sets of intersections using trajectory rods would indicate that there were at least two shooters involved in the crime. The two different intersections suggest that the bullets were fired from different angles and locations, leading to the conclusion that multiple individuals were responsible for the shooting. This information would be crucial in the investigation to identify and apprehend all perpetrators involved.
Database used to find matches to bullets or firearms found at a crime scene?

What is bullet recovery box?
A bullet recovery box is a heavily reinforced box which is designed to deflect and collect bullets fired into it. They are often used when testing bullets or by crime labs checking ballistics.
Why could chromatography be used in investigating the crime?
Chromatography could be used in investigating a crime because it can separate and analyze complex mixtures of substances, such as drugs, poisons, or chemicals found at a crime scene. By identifying and comparing different compounds in samples, chromatography can provide valuable evidence to link suspects, victims, or locations to a crime.
HOW IS TRIGONOMETRY USE IN CRIME INVESTIGATION?
Trigonometry is used in crime investigations to analyze crime scenes and reconstruct events. For example, investigators can calculate angles and distances to determine the trajectory of bullets, assess the positions of witnesses, or map the locations of various evidence. This mathematical approach aids in creating accurate crime scene diagrams and can help establish timelines, making it a vital tool in forensic analysis. Additionally, trigonometric principles can assist in understanding the physical dynamics of incidents, such as falls or collisions.
Can on bullet be an evidence of crime even if you had no gun?
Yes, it can and it has. If a witness can be found that has seen a suspected gun fired at another place or time and those previously fired bullets can be recovered, they can be compared positively or negatively to the bullets used in a crime. This situation has occurred in a number of real cases and was effective evidence in court against a defendant who had disposed of the gun used in the crime when the gun could not be found.

What do forensic sciences do?
Dead bodies, gunshot bullets, knives, scares probably anything that has to deal chemically with a crime scene.
What is the name of the study of bullets and how they are fired?
There is no such thing as the "study of bullets", except, perhaps, as a historian. However, one may study the effectsof bullets using "ballistics", and a person who does so for a living would be called a "ballistics expert"; someone who is trained to do such at a crime scene or laboratory may also be called a "forensics specialist", but the word "forensics" has nothing to do with bullets.
Can there be more than one crime scene?
Yes, there is the primary crime scene and the secondary crime scene. For example, if a body was found in a trash can but there is no evidence that the person was killed there then it means the person was killed somewhere else. The primary crime scene is where the person was killed and the secondary crime scene is where the body was dumped.
