2 What is Forensic ballistics? Forensic ballistics attempts to establish the true facts in a shooting crime Forensic ballistics attempts to establish the true facts in a shooting crime Ballistic evidence includes Ballistic evidence includes Firearms Firearms Bullets Bullets Cartridge cases Cartridge cases

3 Major Types of Ballistic Evidence Bullet holes Bullet holes Bullet damage Bullet damage Bullet trajectories Bullet trajectories Gunshot wounds Gunshot wounds

4 Internal Ballistics Internal Ballistics studies all of the processes inside a firearm. Internal Ballistics studies all of the processes inside a firearm. Most common responsibilities are: Most common responsibilities are: Examining firearms in case of accidental discharge Examining firearms in case of accidental discharge Examining homemade devices called zip guns Examining homemade devices called zip guns The microscopic examination of fired bullets and cartridge cases The microscopic examination of fired bullets and cartridge cases

5 External Ballistics External ballistics studies the projectile of the bullet from the gun to target. External ballistics studies the projectile of the bullet from the gun to target. Two common types of external ballistics are: Two common types of external ballistics are: Calculation and reconstruction of bullet trajectories Calculation and reconstruction of bullet trajectories Establishing the maximum range of a given bullet Establishing the maximum range of a given bullet

6 Terminal Ballistics Terminal ballistics is the study of the projectiles effect on the target. Terminal ballistics is the study of the projectiles effect on the target. The target can be any solid or living object The target can be any solid or living object When the target is human or animal this is often referred to aswound ballistics When the target is human or animal this is often referred to aswound ballistics

7 Types of Terminal Ballistics Determination of distance between firing and target Determination of distance between firing and target Establishing whether a particular wound was caused by a fired bullet Establishing whether a particular wound was caused by a fired bullet Determining the caliber and type of projectile that caused the wound Determining the caliber and type of projectile that caused the wound Identifying exit/entrance by examining holes in targets or wounds Identifying exit/entrance by examining holes in targets or wounds Examination of ricochet possibilities on targets and fired projectiles Examination of ricochet possibilities on targets and fired projectiles
