    Study Notes

    Forensic Ballistics Overview

    • Branch of forensic science that deals with the examination of firearms, ammunition, and related evidence.
    • Primarily used in criminal investigations to determine the origin and trajectory of bullets.

    Key Concepts

    1. Firearms Identification

      • Process of matching bullets and cartridge cases to specific guns.
      • Based on unique markings left by the firearm on the ammunition.
    2. Ballistic Evidence

      • Includes bullets, cartridge cases, gunshot residues, and firearms.
      • Analyzed for comparison and to establish connections between crime scenes, victims, and suspects.
    3. Types of Ballistics

      • Internal Ballistics: Study of the processes within a firearm when it is fired.
      • External Ballistics: Examines the flight of the projectile through the air until it hits a target.
      • Terminal Ballistics: Focuses on the effects of the projectile upon impact with a target.
    4. Trajectory Analysis

      • Involves calculating the path a bullet took.
      • Factors include angle of entry, distance, and environment.
      • Can help reconstruct crime scenes.
    5. Gunshot Residue (GSR)

      • Tiny particles expelled when a firearm is discharged.
      • Collection and analysis can indicate whether a person fired a weapon or was near a discharged firearm.

    Techniques and Tools

    • Comparison Microscope: Used to compare bullet and cartridge case markings side by side.
    • 3D Laser Scanning: For detailed mapping of crime scenes and bullet trajectories.
    • Chemical Tests: To detect gunshot residue on hands or clothing.
    • Testimony from forensic ballistics experts can be crucial in court.
    • Evidence must be collected and preserved following strict protocols to maintain chain of custody.

    Limitations

    • Variability in manufacturing processes can lead to challenges in identification.
    • Environmental factors can affect trajectory and GSR evidence.

    Importance in Criminal Investigations

    • Aids in linking suspects to crimes.
    • Provides critical evidence in cases of homicide and violent crimes.
    • Supports reconstruction of events leading to a shooting incident.

    Forensic Ballistics Overview

    • Forensic ballistics encompasses the examination of firearms, ammunition, and relevant evidence in criminal investigations.
    • Aims to identify the origin and trajectory of bullets to aid in solving crimes.

    Key Concepts

    • Firearms Identification

      • Matches bullets and cartridge cases to specific firearms through unique markings.
    • Ballistic Evidence

      • Comprises components like bullets, cartridge cases, gunshot residues, and firearms for analysis and connection of crime scenes, victims, and suspects.
    • Types of Ballistics

      • Internal Ballistics: Investigates firearm processes during discharge.
      • External Ballistics: Examines projectile flight until impact.
      • Terminal Ballistics: Analyzes projectile effects upon reaching a target.
    • Trajectory Analysis

      • Calculates the bullet's path, considering angle of entry, distance, and environmental factors, instrumental for crime scene reconstruction.
    • Gunshot Residue (GSR)

      • Consists of minute particles released when a firearm is fired; its collection and analysis determine if a person fired a weapon or was near a discharged firearm.

    Techniques and Tools

    • Comparison Microscope: Utilized for side-by-side analysis of bullet and case markings.
    • 3D Laser Scanning: Provides detailed mapping of crime scenes and bullet trajectories.
    • Chemical Tests: Detects gunshot residue on individuals’ hands or clothing.
    • Testimony from forensic ballistics professionals is vital in court proceedings.
    • Protocols for evidence collection and preservation are critical to maintaining chain of custody.

    Limitations

    • Variability in firearm manufacturing processes can complicate ammunition identification.
    • Environmental conditions may influence trajectory and gunshot residue evidence.

    Importance in Criminal Investigations

    • Establishes links between suspects and criminal activity.
    • Offers essential evidence for homicide and violent crime cases.
    • Aids in reconstructing events surrounding shooting incidents.
